| Stoma | Small openings(pores) in the surface layers of the leaf |
| Transpiration | The process of which water evaporates from the plant’s leaves |
| Embrye | The young plant that develops from the zygote, or fertilized egg |
| Germination | When the embryo begins to grow again and pushes out of the seed |
| Flower | The reproductive structure of an angiosperm |
| Pollination | The transfer of pollen made from male reproductive structures to female reproductive structures |
| Sepal | A budded flower enclosed by leaflike structures |
| Stamen | The male reproductive parts |
| Pistall | The female parts found at the center of most flowers |
| Ovary | A tube that protects the seeds as they develop |
| 3 functions of roots | Anchor a plant in the ground, absorb water and minerals from the soil, and sometimes store food |
| 2 functions of stems | Carry substances between a plant’s stems and leaves, and provide support for the plant to hold up the leaves so that they are exposed to the sun |
| Function of leaves | Capture the sun’s energy to carry out photosynthesis |
| 3 basic parts of a seed | Embryo, stored food, seed coat |
| 3 ways a seed can be dispersed | Passing through a digestive system, enclosed n structures that hook onto fur or clothing, or the seeds fall off in a new area |
| Structures of a flower | |
| What each part of a flower does | Sepals protect the developing flower; petals attract pollinators; stamens are the male reproductive parts; pistils are the female reproductive parts |
