1. Chloroplasts: it is the site of photosynthesis.\n \n2. Vacuole: they are storage sites within a plant cell.

The rigid cell wall in plants prevent bursting or shrivelling because, when water enters the cell, the plasma membrane cannot expand past the cell walls. Similarly, in hypertonic situations, the plasma membrane will just tear away from the cell wall. The cell does not lose its shape because the cell walls are still there and in the same shape.

The first thing you will see is the structure of the cells which form tissue. Inside the cell, there's nuclues which contols all the activities in the cell. Protoplasm stands for cytoplasm and nuclues(extra info).

Here is what i could fined but i was unable to find anything on the leaf eperdemal cells.\n\nA red blood cell is - a cell in the blood of vertebrates that transports oxygen and carbon dioxide to and from the tissues\n\nprotozoans - Any of a large group of single-celled, usually microscopic, eukaryotic organisms, such as amoebas, ciliates, flagellates, and sporozoans.\n\nPhloem - the part of a vascular bundle consisting of sieve tubes, companion cells, parenchyma, and fibers and forming the food-conducting tissue of a plant. \n\nMuscle cells - an elongated contractile cell that forms the muscles of the body\n\n Xylem -a compound tissue in vascular plants that helps provide support and that conducts water and nutrients upward from the roots, consisting of tracheids, vessels, parenchyma cells, and woody fibers.

They're talking about the plant cell model...not the actual plant cells.

Plant cells differentiate in many tissues, like leaf, xilem, phloem, root and many others. It's the same for us, an animal cell can differentiate into a liver cell, a brain cell, a skin cell....\nPlants, unlike us, have regions of undifferentiated cells, called meristems. The main meristem of the shoot is at the top, called the terminal bud. Theese cells divide and produce the elongation of the shoot, and as they become more and older they produce new shoot, leafs and stuff.\nOther meristems, axial buds, are kept right in the place where the leaf meets the shoot. When this buds start growing in the same way the terminal buds do, branches arise.\nOther regions of meristematic tissue are right between the phloem (where the sap flows) and the xilem (where the water flows) all along the shoot. This region is called the Vascular Cambium.\n\nNormally, the terminal bud secretes hormones to the sap that keep the other meristematic tissues at rest. This is to avoid a lot of branches beeing produced before the roots can cope with the water demand of a lot of leafs.\nWhen you cut the shoot, the terminal bud dissapears, so the axial buds and even the cambium start dividing and differentiating into new shoots. \nThe reason why this new growth happens near the cut is because this would be the youngest axial buds and cambium, and therefore the most active ones (or the ones that can more readily be activated).

Cell membranes and cytoplasm are structures of all cells--both prokaryotic and eukaryotic.  Prokaryotic cells do not have any of the membrane-bound organelles, such as a nucleus, Golgi body, endoplasmic reticulum, etc.

In a hypertonic solution the water inside the cell leaves, causing the cell to shrivel.  Since a plant cell has a cell wall, the cytoplasm and plasma membrane will shrink away from the cell wall (called plasmolysis).  This decrease in turgor pressure means the plant will wilt.

id say the plants and animals are multi-celled and the others are single-celled. also cell specilization could be a difference.

cell wall - a thick, rigid membrane that surrounds a plant cell. This layer of cellulose fiber gives the cell most of its support and structure. The cell wall also bonds with other cell walls to form the structure of the plant.\n\nYou will find the rest here --> http://www.enchantedlearning.com/subjects/plants/cell/

Hi Erica, \n\nI'd waste both your and my time if I try to answer this question with lots of detail. I'd suggest you go to your textbook, flip a few pages here and there, get a broad idea and then, come back and read this answer. \n\nPlease notice that I'll have to make this answer less complex by generalizing concepts and avoiding some fine details which you can easily read in your textbook.\n\nNow, without wasting much time, here is my answer-\n\n===================\n\nCharacteristics of animal sexual life cycles-\n\n1- Usually, there are two parents- male and female. Both form special haploid cells called gametes by meiosis.\n\n2- Gametes fuse in pairs to form diploid cells called zygotes (fertilization).\n\n3- Repeated mitotic divisions of the zygote forms embryos.\n\n4- And the embryo develops into a new individual.\n\nSooo simple!\n\n====================\n\nCharacteristics of plant sexual life cycles-\n\nIt is same as animal sexual reproduction. Just that the technical terms and the methods of reproduction are a little different in flowering and non-flowering plants. I suggest you to read your textbook for the detailed terminology.\n\nIn plants-\n\n1- Diploid sporophytic cells divide by meiosis to give haploid gametophytic cells.\n\n2- Haploid gametophytic cells from male and female fuse to form the diploid zygote.\n\n3- The zygote then develops into an embryo and then to a full diploid plant body.\n\n* There are lots of finer details like the flowering system in flowering plants: pollens, ovules etc. and sporangia in non-flowering plants. I suggest you to study the life cycles of different bryophytes, gymnospermae and angiospermae to get the idea.\n\n================\n\nCharacteristics of fungal sexual life cycles-\n\n1- It involves fusion of two compatible sex cells/ gametes. The sex organs that produce gametes are called gametangia.\n\n2- The gametangia of fungi are unicellular and are surrounded by a sterile jacket. In fungi, there is a gradual reduction in sexuality from lower to the higher fungi.\n\n3- In the first stage, the cytoplasms of two sex cells fuse with each other but the nuclei do not fuse. The cell is thus called a dikaryon. (Plasmogamy).\n\n4- The nuclei then fuse to form the synkaryon. (Karyogamy).\n\n5- The diploid cell after that, produces haploid nuclei by meiosis.\n\nThere are broadly five types of sexual fusion in fungi.\n\nHere they are-\n1- Planogametic copulation. \nOne or both of the gametes are motile.\n\n2- Gametangial contact. \nThe two gametangia come together and the male gametangia forms a tube through which the male non-motile gamete is sent to the female gametangia.\n\n3- Gametangial copulation. \nThe gametangia themselves fuse together and lose their sexual identities to form zygospore.\n\n4- Spermatization. \nNumerous spore-like minute bodies (spermatia) are sent through various agencies to the receptive hyphae or trychogyne of female gametangium.\n\n5- Somatogamy.\nIn this mode, sex organs are not formed and the fusion occurs two vegetative cells resulting in the formation of dikaryon.\n\n=================\nI hope the above info helps.

Plant cells have a rigid cell wall so during telephase (cytokinesis), they use a different method of divergence ('splitting' of the cell). The process is complicated, so state that plant cells do not cleave like animal cells and that they produce a cell plate from the Golgi apparatus. Also, plant cells don't have centromeres and instead use astral fibres.\n\nBefore mitosis begins, chromosomes are replicated so that their numbers are doubled.\n\nAfter a cell undergoes mitosis, the two new cells are completely identical and have the same DNA. A difference which may occur, but is of little importance, is that one cell may receive more organelles then the other when division occurs by chance.\n\nIt's important for the nuclear membrane to disintegrate during mitosis so that the chromosomes can attach to the spindle fibres and allign at the metaphase plate (or the 'equator'). It's also required so that the chromosomes can be pulled apart from each other during anaphase, and allow the division of the cell.
