|
Ovary |
Where seeds are produced |
|
|
Stomata |
Pores in a leaf mostly on the undersurface |
|
|
Vascular Tissue |
Transport system within a plant Includes Xylem and Phloem |
|
|
Xylem |
Creates annual rings, which can tell us how dry or wet that half a year was. Carries Water up through the plant starting with the roots |
|
|
Phloem |
Carries food-sugars up and down through a plant Food is made in the leaves and then travels to other parts of the plant |
|
First leaves |
Take some time to develop and can photosynthesize
|
|
Cotyledon |
To store energy
(high in starch(sugar) and protein) |
|
Embryonic Roots |
First root to start to bring water into first leaves
|
|
Seed Coat |
Forms a protective layer around the embryo and cotyledons.
Lets water in to start to germination. |
|
