What are some plant parts?

Question

I need these answers for a project.

Answer 1

Plant Parts:  Stamen, pistol, petals, stalks, leaves, roots are just some parts of many plants.

According to Wikipedia:  http://en.wikipedia.org/wiki/Stamen

"The stamen (plural stamina or stamens, from Latin stamen meaning "thread of the warp") is the male organ of a flower. Each stamen generally has a stalk called the filament (from Latin filum, meaning "thread"), and, on top of the filament, an anther (from Ancient Greek anthera, feminine of antheros "flowery," from anthos "flower"), and pollen sacs, called microsporangia. The development of the microsporangia and the contained haploid gametophytes, (called pollen-grains) is closely comparable with that of the microsporangia in gymnosperms or heterosporous ferns. The pollen is set free by the opening (dehiscence) of the anther, generally by means of longitudinal slits, but sometimes by pores, as in the heath family (Ericaceae), or by valves, as in the barberry family (Berberidaceae). It is then dropped, or carried by some external agent — wind, water or some member of the animal kingdom — onto the receptive surface of the carpel of the same or another flower, which is thus pollinated.

Typical flowers have six stamens inside a perianth (the petals and sepals together), arranged in a whorl around the carpel (pistil). But in some species there are many more than six present in a flower (see, for example, the spider tree flower, below). Collectively, the stamens are called an androecium (from Greek andros oikia: man's house). They are positioned just below the gynoecium. The anthers are bilocular, i.e. they have two locules. Each locule contains a microsporangium. The tissue between the locules and the cells is called the connective...

In the typical flower (that is, the majority of flowering plant species) each flower has both a pistil and stamens. Bisexual plants are named hermaphrodites or perfect flowers.

In some species, however, the flowers are unisexual with only either male or female parts (monoecious = on the same plant; dioecious = on different plants). A flower with only male reproductive parts is called androecious. A flower with only female reproductive parts is called gynoecious"

According to Wikipedia:  http://en.wikipedia.org/wiki/Flower

"Flowering plants are heterosporangiate, producing two types of reproductive spores. The pollen (male spores) and ovules (female spores) are produced in different organs, but the typical flower is a bisporangiate strobilus in that it contains both organs.

A flower is regarded as a modified stem with shortened internodes and bearing, at its nodes, structures that may be highly modified leaves."

Check out the illustrations in this article for more parts of the flower identified.  This is probably what your teacher is looking for.

Unicellular plants like plankton and alga have their own structure, but it is all internal.  Not all plants are flowering plants, but most are.  Otherwise multicellular plants have roots, a stem, stalk, trunk or branch, and leaves (petals are specialized leaves as are thorns).

According to Wikipedia:  http://en.wikipedia.org/wiki/Plant

"Aristotle divided all living things between plants (which generally do not move), and animals (which often are mobile to catch their food). In Linnaeus' system, these became the Kingdoms Vegetabilia (later Metaphyta or Plantae) and Animalia (also called Metazoa). Since then, it has become clear that the Plantae as originally defined included several unrelated groups, and the fungi and several groups of algae were removed to new kingdoms. However, these are still often considered plants in many contexts, both technical and popular."

Answer 2

The major parts of a seed plant are the roots, stems, and leaves.  In addition, there are reproductive structures such as flowers producing seeds.  Each of these are composed of various tissues such as epidermis, ground tissues, vascular tissues, and meristematic tissues.

Go to the library to obtain a botany book or do a search on the web for more information.  There is massive amounts of information about plants.  You can earn a doctorate in botany with specialty in anatomy or morphology of plants.

Answer 3

Roots, stem, leaves, flowers, fruits, seeds

Answer 4

stigma, pistil. i dunno i just did a report on a plant reproductive systems. on sea weed the leaves are called blades.
