2.  Root System  Stems  Leaves  Flowers  Other

3.  There are generally two types  Fibrous- 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

4.  The stem supports other plants such as the leaves, flowers, and fruit  Two basic types of aboveground stems are woody and herbaceous

5.  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

6.  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

7.  The male part is the stamen and consists of the:  Filament that supports the anther  Anther that manufactures pollen  Pollen that is the male sexual reproductive cell

8.  The female part is the pistil and consists of the  Stigma that receives the pollen  Style that is the connection to the ovary  Ovary that contains the ovules (female reproductive cells)

9.  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

10.  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
