55. Angiosperms are more advanced that gymnosperms because gymnosperms lack which structure found n angiosperm

Here's what I learned:\n\nBoth gymnosperms and angiosperms have vascular tissue and both produce seeds. However, the seeds of angiosperms are surrounded by the wall of the ovary of the flower which forms the fruit, whereas gymnosperms do not possess this structure. Their seeds are described as naked (Gymnosperm from the Greek: gymnos - naked, sperm - seed). Botanists place the angiosperms in the group (division) Angiophyta but the Gymnosperms do not form a coherent group and are separated into four divisions.\n(from http://www.botany.uwc.ac.za/ecotree/gymangio.htm)\n\nI don't really see the wall of the ovary as one of the choices you offer.  I guess the answer is C--fruits.

cell walls give structure.

Your question is flawed some conifers are deciduous i.e larch, dawn redwood, ginko, bald cypress.  Your question should either be... What is difference between evergreens and deciduous plants? or What is the difference between gymnosperms and angiosperms?

Whitch is not a word and if you mean "which", you need to give multiple choices for us. Otherwise say, "what plants contain phloem and xylem?"

Only plants have chloroplasts and cell walls.

Angiosperm Life Cycle\nI. Plant Life Cycles\n\nA. All of us are probably most familiar with the human life cycle. We know that, as adults, most of our cells have two sets of chromosomes, one from our mother and the other from our father. These cells (really the chromosome complement of their nuclei) are called diploid (2N). Special cells undergo meiosis where the chromosome number of the resulting cells are half that of the parent cell. These cells are haploid (1N) and develop directly into gametes (sperm and egg). These gametes fuse during fertilization to produce a zygote which divides through mitosis to form the adult organism. Bear in mind, the two important events in any life cycle (animal or plant) are fertilization and meiosis.\n\nB. In plants, things are a bit different because the products of meiosis (spores) don't immediately become gametes. They divide mitotically to form a completely separate organism! This organism is called the gametophyte and is haploid. The gametophyte may be composed of many cells and be a fully functional plant (such as the green leafy moss) or be composed of only a few cells (as in flowering plants).\n\nC. So how are the gametes formed? The gametophyte produces special structures that make the gametes via mitosis. After fertilization occurs, a diploid zygote forms and grows via mitosis to form the sporophyte which is diploid. This life cycle is called alternation of generations {0256}{0257}{0517}, because the gametophytic and sporophytic stages alternate with each other.\n\nII. Angiosperm Life Cycle {1075}\n\nA. Production of the male gametophyte {0258}. Each anther contains from one to four microsporangia. A microsporangium contains microspore mother cells (microsporocytes) that undergo meiosis producing haploid microspores {0291}{0294}{0295}. Each of the four components of the tetrad {0296} differentiate into pollen grains {0289}. Mitotic divisions result in a mature microgametophyte, otherwise known as pollen. Each pollen grain contains a tube nucleus and a generative nucleus {0290}. When the pollen grain lands on the stigma (below), the generative nucleus divides to form two sperm nuclei. {1086}\n\nB. Production of the female gametophyte {0259}. Inside the ovary are the ovules {0511} that eventually become seeds. The megaspore and later the megagametophyte form inside the ovule. The megagametophyte eventually produces the egg, the female gamete.\n\nInside a young ovule, one cell differentiates into a megaspore mother cell (megasporocyte) {0562}. Meiosis produces four megaspores, but usually only one of these survives. It divides mitotically three times {0563}{0565} giving eight nuclei (in seven cells) {0568}. One cell at the micropyle end of the ovule becomes the egg and the two nuclei in the large central cell function as polar nuclei.\n\nC. Pollination {0260}{0518}{1086}. If the pollen grain is on a compatible stigma, it attaches, germinates and forms a pollen tube which grows through the style tissue on its way to the ovule.\n\nD. Fertilization. When the pollen tube reaches the micropyle opening, it releases two sperm nuclei. One fuses with the egg forming a zygote {0261}, the other fuses with the already fused polar nuclei making a triploid fusion nucleus. This DOUBLE FERTILIZATION is a feature found only in angiosperms. The triploid fusion nucleus divides mitotically to form endosperm which is used as a nutritive tissue for the growing embryo {0615}.\n\nD. Fruits and seeds {0538}. The mature ovule becomes the seed. The integuments become the seed coat that surrounds the endosperm and embryo. The mature carpel (and sometimes associated tissues) becomes the fruit.

There are about 250,000 angiosperm species (flowering plants and trees), and about 80,000 gymnosperm species.  Include the other groupings, and the total comes to about 370,000.\n\nThat said, it is estimated that we have discovered only between 10 and 40% of all known species (and we probably never will discover them given the rate of destruction of habitats such as rain forests.\n\nSo the total is probably between 1.5 and 3.7 milliion, though it's a moot point because we'll never, ever know!

Both are eukaryotic (containing a "true nucleus").  \n\nAnimal Cells lack a cell wall and adjacent cells are connected by junctions (adhesive, gap or tight).  Animal cells contain centrioles (help create microtubules used in mitosis and meiosis) and lysosomes (organelles used to digest wastes and old organelles). During telophase and cytokinesis the cells separate via a cleavage furrow.\n\nPlant Cells contain a cell wall (think of the cell wall as the "skeleton" composed mainly of cellulose) and rely on turgor pressure to keep them upright.  Adjacent cells are connected by channels called plasmodesmata.  You will not find centrioles or lysosomes in a plant cell, but you will find a really cool organelle called a large centrol vacuole.  This organelle is where the water is stored in a cell and it helps maintain the turgor pressure described above.  It also acts as a lysosome, storing chemicals and waste products.  The Central vacuole can also store the pigments you see in flowers as well as poisons used to deter predators.  And of course, in a plant cell you will find the plasts as mentioned by someone earlier.. including the famous chloroplasts (the site for photosynthesis) as well as the chromoplasts (contain pigments) and amyloplasts (specialized for starch storage). During telophase and cytokinesis, the cells are separated by a structure called a cell plate.   \n\nUmmm, that's all I can come up with right now!

to have a good idea have a look at the article below. hoppe it helps... it's a bit long but will have what you need properly explained...\n\n\n\nPollination Adaptations\nFlowers need to be pollinated. Pollination is the process of moving the pollen grain from the anther of a stamen to the stigma of a carpel. There are a few flowers that can self-pollinate all on their own, but this limits them to inbreeding. Most species rely upon some kind of pollination vector to accomplish pollination. The vector can be any agent that can move pollen from anther to stigma. \n\nThere is evidence of water and wind as the pollination vector in certain species, but many species do not depend upon the random or downstream-only pollination pathways offered by these vectors. Indeed such vectors are only useful in situations where large populations of a very limited number of species are present. \n\nMost flowers have evolved to use a "smart bomb" or "magic bullet" vector...animals! These vectors have sensory organs to locate flowers, they have locomotion to get them to the flowers in spite of large spaces between individuals, and they have enough intelligence to remember that they can depend upon a reward if they visit one particular species repeatedly. \n\nAttracting the Pollinator\nIn order to effectively use an animal pollination vector, a flower needs to attract the animal for the first visit. This can be done in one of two ways: visual cues and olfactory cues. \n\nVisual Cues\nSome species use a color pattern known as a "bull's eye" to mark their position in the environment...to stand out against a background of green foliage. Obviously not too many animal-pollinated flowers are leaf-green! \n\na black-eyed susan...recall that there are over 100 species of unrelated black-eyed susans...one of the problems of common names. This one is in the genus, Rudbeckia. Notice its obvious bull's eye target appearance. The bull's eye is black and the yellow ring surrounds it to make it quite noticeable. \n\n\nThe daylily (Hemerocallis) also shows a prominent bull's eye, but notice how the color pattern is reversed. The bull's eye is light in color and the ring around it is very dark. The effect is the same however, the flower is going to be obvious to a potential pollinator flying overhead. \n\n\nIt is important that whatever color pattern is used is within the visible range of colors observable by the pollinator. Colors obvious to one animal may be invisible to another. Gaillardia (painted daisy). This species obviously uses a yellow bull's eye with surrounding red and yellow rings. One gets the appearance of a dartboard just looking at it. The pollinator visiting is butterflies. Butterflies definitely are attracted to red/yellow patterns, and they need the large landing platform provided by this wide flower. \n\n\nOn the other hand, Gaillardia does not limit its pollination to just butterflies. An afternoon of observation will tell you that even more visits are made by honeybees! Bees have no ability to perceive red colors, so how does that red/yellow pattern look to a bee? This requires some mental translation and some special photography for a human to appreciate what a bee might observe. \n\nFirst we need to eliminate red from the image. This can only be accomplished with fancy video work or black-and-white photography.\n\n\nBee vision does not include red, but it does extend into the ultraviolet. In other words, bees see colors that are invisible to us! Our film is not very sensitive to ultraviolet because it has been developed for showing images visible to humans. To correct that and see the ultraviolet patterns in these flowers, we need to use yet another filter. This filter blocks visible light and allows ultraviolet light to expose the film. Below is the ultraviolet image of the same two daisies taken seconds later with both filters in place: \n\n\ncenter of each daisy is totally absorbin

No the plant could not produce starch without chlorophyll. They synthesize the sugar from water and carbon dioxide in a process called photosynthesis.

In angiosperms there is fruit as well as seed formation. \nIn gymnosperm ther is only seed formation but no fruit formation, this is the most important and major difference between them.\nEdit-: The difference I quoted   above   is the major and the fundamental one. The other differences are as follows:- Gymnosperms are all trees, some of them are very tall and massive. The Angiosperms,\n on the other hand, can be trees, herbs as well as shrubs.\n Internally (Anatomically speaking) Gymnosperms  have; Tracheids in xylem and sieve cells in phloem , companion cells are absent. Their xylem walls have bordered pits.\nIn Angiosperms, true vessels i.e. tracheae are present in xylem. Sieve tubes and companion cells are present in phloem. Their xylem walls show simple pits.\nGymnosperms are more ancient than the Angiosperms.\n I only hope that you understand the botanical terminology in the above text.
