Plants
What are plants?
Plants are multicellular organisms in the kingdom Plantae that use photosynthesis to make their own food. They produce most of the world's oxygen, and are important in the food chain, as many organisms eat plants or eat organisms which eat plants. The study of plants is called botany.
Types of Plants
There are many different types of plants. They are typically divided into two major groups: vascular and nonvascular.
Vascular - These plants have specific tissues that help to move materials such as water through the plant. They are further divided into non-flowering plants and flowering plants. Most of the organisms you probably think of as plants, such as trees, bushes, and flowers, fit into this group.
Nonvascular - These are smaller plants, such as mosses, that use diffusion and osmosis to move material through the plant
Plants are classified in 4 different groups
The kingdom Plantae consists of four major plant groups on land: bryophytes (mosses), pteridophytes (ferns), gymnosperms (cone-bearing plants), and angiosperms (flowering plants). Plants may be categorized as vascular or nonvascular. A vascular plant has tissues for transporting water or sap.

Bryophytes
Bryophytes are small,
non-vascular plants, such as mosses, liverworts and hornworts. They play a
vital role in regulating ecosystems because they provide an important buffer
system for other plants, which live alongside and benefit from the water and
nutrients that bryophytes collect.
Pteridophytes
Pteridophytes are vascular
plants and have leaves (known as fronds), roots and sometimes true stems, and
tree ferns have full trunks. Examples include ferns, horsetails and
club-mosses. Fronds in the largest species of ferns can reach some six meters
in length.
Angiosperms
Angiosperms are vascular
plants. They have stems, roots, and leaves. Unlike gymnosperms such as conifers
and cycads, angiosperm's seeds are
found in a flower. Angiosperm eggs are
fertilized and develop into a seed in an ovary that is usually in a flower.
