Unit 2 Lesson 1
Plant Survival
| Term | Definition |
|---|---|
| Stomata | Spores in the bottom of leaves that open and close to let in or give off gases (oxygen, carbon dioxide, water vapor) |
| Xylem | The plant tissue through which water and minerals move up from the roots. |
| Transpiration | The evaporation (release) of water vapor (gas) through the stomata of a plant |
| Phloem | The plant tissues that transport food (glucose) from the leaves to the rest of the plant. |
| Roots | The part of a plant that absorbs water and nutrients from the ground. Anchor the plant and can sometimes store food. |
| Stem | The part of a plant that transports water from the roots to the leaves. It also holds the plant up toward the sun and transports food and nutrients. |
| Leaves | The part of a plant where food (glucose) is made using water, carbon dioxide, and energy from the sun through a process called photosynthesis. |
| Flowers | The reproductive structure of a plant. If pollinated, a fruit/seed will form. The seed will sprout to form a new young plant. |
| Energy | The ability to do work or change something |
| Seed Dispersal | Ways that seeds are spread to help give plants space. Examples: Wind, Water, Animals, Explosive |
| Photosynthesis | The food making process that occurs mainly in the leaves of plants. The plant uses water, carbon dioxide, and energy from sunlight to make food (glucose) for the plant. |
