| Anther | the pollen-bearing part at the upper end of the stamen of a flower. |
| Egg | the female sex cell in plants. |
| Fertilization | the stage in the life cycle of a flowering plant in which the sperm cell (pollen) joins with an egg cell in the ovule. |
| Filament | the stalk of the stamen which supports the anther. |
| Ovary | the base of the pistil of a flower that contains the ovules. |
| Ovule | the part of the ovary of seed plants that contains the egg cell and after fertilization becomes the seed. |
| Pistil | the female part of flower that consists of the stigma, style, and ovary. |
| Pollen | the male sex cells in plants. |
| Pollination | the transfer of pollen from the stamen to the pistil of a plant. |
| Stamen | the male part of a flower that consists of the anther and filament. |
| Stigma | the sticky top of the pistil where pollen grains land. |
| Style | a stalk on the pistil down which the pollen tube grows after pollination has taken place. |
| Cotyledon | an embryonic leaf in seed-bearing plants, one or more of which are the first leaves to appear from a germinating seed. |
| Fibrous roots | several main roots that branch off to form a mass of roots. |
| Nonvascular plant | a plant that lacks tube-like structures and must obtain nutrients directly from the environment and distribute it from cell to cell. |
| Phloem | a type of vascular tissue that transports food from the leaves down to the rest of the plant. |
| Root hairs | thin fibers on a root that greatly increase its surface area. |
| Seed | a flowering plant’s structure for reproduction, capable of developing into a new plant. |
| Taproot | one large, main root with smaller roots branching off. |
| Vascular plant | a plant with tube-like structures that provide support and help circulate water and food throughout the plant. |
| Xylem | a type of vascular tissue that transports water and minerals up from the roots to the rest of the plant. |
| Embryo | the beginnings of roots, stems, and leaves in a seed. |
| Seed coat | the protective covering of a seed that protects it from injury and also from drying out. |
| Herbaceous stem | a plant stem which is soft and green and dies down to the soil level at the end of the growing season. |
| Woody stem | a plant stem which is hard and rigid. |
| Flower | The part of a plant that produces the seed and usually contains petals, a pistil, and pollen-bearing stamens. |
