what is the function of pollen and seeds?

Pollen, or flower sperm, is a fine to coarse powder consisting of microgametophytes (pollen grains), which carry the male gametes of seed plants. Each pollen grain contains one or two generative cells (the male gametes) and a vegetative cell. The group of three cells is surrounded by a cellulose cell wall and a thick, tough outer wall made of sporopollenin.\nThe transfer of pollen grains to the female reproductive structure (pistil in angiosperms) is called pollination. This transfer can be mediated by the wind, in which case the plant is described as anemophilous (literally wind-loving). Anemophilous plants typically produce great quantities of very lightweight pollen grains, often with air-sacs, and generally have inconspicuous flowers. Entomophilous (literally insect-loving) plants produce pollen that is relatively heavy, sticky and protein-rich, for dispersal by insect pollinators attracted to their flowers.\n\nWhen placed on the stigma, under favorable circumstances, the pollen-grain puts forth a pollen-tube which grows down the tissue of the style to the ovary, and makes its way along the placenta, guided by projections or hairs, to the mouth of an ovule. The nucleus of the tube-cell has meanwhile passed into the tube, as does also the generative nucleus which divides to form two male- or sperm-cells. The male-cells are carried to their destination in the tip of the pollen-tube.\n\nA seed is the ripened ovule of gymnosperm or angiosperm plants. The importance of the seed relative to more primitive forms of reproduction and dispersal is attested to by the success of these two groups of plants in dominating the landscape.

It supports the plant.It also contains the xylem and phloem. The xylem transports water and minerals from the roots to the rest of the plant.The phloem transports food made in the leaves to the rest of the plants. :)

If it is the same species of flower, the pollen lands on the stigma (easy to remember...stigma ma mother ei female / stamen....men....male) a chemical reaction occurs that makes the pollen develop a tube/ straw that leads down the stigma to where the seeds are...get a text book out for this cant remember the name of that thing....the DNA is then taken up by the flower in the production of the seed....Oooo dear so many years ago.....cant remember a thing properly

http://en.wikipedia.org/wiki/Golgi_complex\n\nThe primary function of the Golgi apparatus is to process and package macromolecules synethesised by the cell, primarily proteins and lipids. The Golgi apparatus forms a part of the endomembrane system present in eukaryotic cells.

birds and bees pollenate flowers which make them grow and flourish and their seed then spread and the cycle starts again. like people male pollenate women then the stork comes and bring a new baby. wink,wink,nod,nod,righteo,righteo.

Asexual reproduction is cloning. A piece of a plant may root or sprout and grow into a new plant which is genetically identical with the parent.  \n\nSexual reproduction results in a new plant which contains genetic material from two parents, but which is not genetically identical with either one.   These new plants may be able to adapt more successfully to environmental changes than their parents could.\n     To live and multiply on land, plants needed to evolve new structures and methods for reproduction.  An important advance was the development of the flower, a structure which allowed widespread scattering of its pollen and yet provided a stable, nurturing environment in the ovary for developing seeds.  Pollen could be carried from flower to flower by insects, the wind, or, sometimes, birds.  \n\n     The seed was another important innovation, as significant for plants as the amniotic egg was for land animals.  Seeds would form when the chromosomes of the parents were united in the ovary.  A seed is a compact package made of a cell capable of growing into a plant, food to help the plant get started, and, in angiosperms, a seed coat that protected the seed from dehydration  and  damage in the environment.  Properly protected seeds could survive until conditions favored their development.  In the deserts today, some seeds may lie dormant for many years until the rains come and provide conditions in which the seeds may germinate and grow into plants.  Some seeds also are contained in, or attached to, structures which help the seeds to be carried to other places that may be suitable for them.

This is so they ensure the survival of the plant species by reproducing them self's.  The seeds attract birds and animals to eat them and they in turn help spread the seed.  This is more efficient than pure wind distribution.

In angiosperms, the sporophyte (2n) stage predominates and includes the\nvegetative parts of the plant and even the various parts of the flower. The process involving meiosis, which converts\ndiploid sporocytes (or spore mother cells) into haploid (n) spores, is termed sporogenesis. Sporogenesis occurs in the\nanthers of stamens and the ovules of pistils. Angiosperms, and seed plants in general, are heterosporous. This means\nthat two different kinds of spores, microspore and megaspore, are produced by the sporophyte. Consequently,\nheterosporous organisms exhibit separate male and female gametophytes. The microspore gives rise to the\nmicrogametophyte (or male gametophyte), and the megaspore gives rise to the megagametophyte (or female\ngametophyte).

The primary function of the male reproductive system is reproduction, which includes the production of spermatozoa, the transportation of spermatozoa from the testes out of the male body, the secretion by glands, and the placement of spermatozoa in the female reproductive tract. Spermatozoa are produced in the testes then transported from the testes by a series of ducts which become gradually larger and connect with the urethra of the penis.  Various accessory glands in the male system secrete materials which together with the spermatozoa constitutes the semen. A secondary function of the male reproductive system is the production of the male hormones which are responsible for the secondary sex characteristics of the male animal.\n\nhttp://www.cvm.okstate.edu/instruction/mm_curr/histology/MR/himrp1.htm\n\nThe male reproductive system, like that of the female, consists of those organs whose function is to produce a new individual, i.e., to accomplish reproduction. This system consists of a pair of testes and a network of excretory ducts (epididymis, ductus deferens (vas deferens), and ejaculatory ducts), seminal vesicles, the \nprostate, the bulbourethral glands, and the penis. \n\nhttp://training.seer.cancer.gov/module_anatomy/unit12_2_repdt_male.html\n\nThe organs of the male reproductive system are specialized for the following functions:\n\nTo produce, maintain and transport sperm (the male reproductive cells) and protective fluid (semen) \nTo discharge sperm within the female reproductive tract \nTo produce and secrete male sex hormones \n\n\nhttp://www.cchs.net/health/health-info/docs/2300/2376.asp?index=9117

You have got some things muddled up here.\n\nGestation and offspring dependency doesn't apply to flowering plants.\nSexual maturity and frequency of reproduction - there are three patterns:\n- annuals - life cycle complete within one year, parent plant dies;\n- biennials - life cycle takes two years - first year plant establishes itself, over-winters, reproduces next year and dies;\n- perennials - live for many years and make seeds every year.\nAs for the number of seeds they make, this is very variable. Some species make only a few, some make lots.\n\nLink 1. - general information.\nLink 2. - a bit more detail.\nLink 3. - a site to help with all the technical words, very useful.

Though plants, including trees, sexually reproduce... they contain both sex organs. Look at flowers. Two different flowers contain both pistils and stamens. The pistil (in human equivalent, the penis) and the stamen (in human equivalent, the vagina) are included in every plant. They reproduce by releasing the "seed" through the pistil and having the wind either carry it or a bee carry it to another flower, where the stamen receives it. Hope that helps.

FLowers are the sex organs of the plant.  They are pollinated and make seeds.

Because light is needed for photosynthesis which makes energy..since the seeds have no leaves and hence no photosyntheisis they get around by having enough energy material provided within the seed to allow for growth until plant is above ground and has the leaves needed for photosynthesis

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.
