| Process by which plants make food | Photosynthesis |
| Plant with two seed leaves | Dicot |
| Plant with one seed leaf | Monocot |
| Seed leaf that forms after germination | Cotyledon |
| Breathing pores on the outside of the stem | Lenticels |
| A pore found in the leaf and stem epidermis that is used for gas exchange | Stomata |
| cells in the leaf skin that allows leaves to breath | Guard Cells |
| Part of the cell that contains chlorophyll | Cloroplasts |
| Green pigment in plants | Chlorophyll |
| Large center vein in a leaf | Midrib |
| Epidermis | Skin go the leaf |
| Vascular bundles | Contains the xylem and phloem in monocots |
| Bud scale scar | Where the terminal bud was the previous year |
| Sepals | Protects the floral part |
| Petals | Part of the flower that attracts insects |
| Stamens | Male part of the flower |
| Anther | Produces the pollen |
| Filament | Stalk that supports the anther |
| Pistil | Located in the center of the flower (female ) |
| Stigma | sticky part of the pistil that receives the pollen |
| Style | Narrow extension of the pistil that bears the stigma at the apex |
| Ovary | Bottom part of the sigma eggs cells develop into fruit |
| Ovules | Structure that gives rise to and contain the female reproduction cell, after fertilization ovule develops into a seed |
| Pollen | Carried by insects to fertilize plants |
| Complete flower | has both male and female parts |
| Incomplete flower | Has only male or female parts |
| Flowers | Attracts insects for pollination (sex reproduction) |
| Leaves | Function primarily in food manufacture by photosynthesis |
| Seeds | Function propagation of the plant |
| Stem | Main body of the plant, support, passage for food and water |
| Root | Anchor the plant, help in absorption and food absorption |
| Xylem | Vascular bundle that carries water and nutrients from the root to the leaves |
| Phloem | Vessels of the vascular bundle that carry manufactured food to areas of the plant |
| Adhesion | When water clings to the walls of the xylem |
| Cohesion | Water molecules attract to each other |
| Cambium | Produces all new cells, separates Xylem and phloem |

| Petiole | Stalk like structure that attaches the blade to the stem |
| Absorption | Taking in liquid or gas substance |
| Root hair | Absorb moisture and minerals |
| Osmosis | High to low concentration of water even out pressure |
| Fibrous root | Short more compact root |
| Tap root | Longer and fewer roots |
| Adventitious root | Develops in other places other than the knodes |
| Aerial root | The root above the ground |
| Margin | Edges of the plants leafs |
| Vascular tissue | Veins or vascular bundles |
