Root System Stems Leaves Flowers Other

There are generally two typesFibrous- thin, moderately branching roots

growing from the stem Tap- enlarged, somewhat straight to

tapering plant root that grows vertically downward

Regardless of which types, roots anchor the plant and take in water and nutrients

The stem supports other plants such as the leaves, flowers, and fruit

Two basic types of aboveground stems are woody and herbaceous

The leaf manufactured for for the plant by using light energy

Leaves are useful for identification of plants. The leaf edge (margin), shape, and arrangement are all important in plant identification

The primary function of flowers is the production of seed

A perfect flower contains all male and female parts

Seed develops in the female part of the flower (pistil)

The pistil then enlarges and becomes the fruit

The male part is the stamen and consists of the:Filament that supports the antherAnther that manufactures pollenPollen that is the male sexual reproductive

cell

The female part is the pistil and consists of the Stigma that receives the pollenStyle that is the connection to the ovaryOvary that contains the ovules (female

reproductive cells)

Petals are the colored part of the flower that attract insects or other natural pollinators

All the flower petals together are called the corolla

Sepals function as a protection for the developing flower

The sepals are collectively called the calyx

Endosperm- supplies food for the germinating seed

Embryo- the young plant itself Seed coat- protects the seed

Sometimes the seed coat is very hard and difficult to germinate

Horticulturalist assist germination by scarifying the seed coat or damaging the seed coat to promote germination
