Chapter 3 plants
Lesson 3
| Term | Definition |
|---|---|
| Stomata | tiny pores on the surface of plant leaves and stems that regulate the exchange of gases like carbon dioxide and oxygen, and are crucial for photosynthesis and transpiration |
| Transpiration | The process by which water is lost through a plant's leaves |
| Germination | The sprouting of the embryo out of a seed; occurs when the embryo resumes it’s growth following dormancy |
| Respiration | the process of converting stored carbohydrates into energy (\(ATP\)) for growth and other cellular activities |
| Flower | The reproductive structure of an angiosperm |
| Pollination | The transfer of pollen from male reproductive structures to female reproductive structures in plants |
| List the three functions of roots | 1. The roots anchor the plant. 2. The roots absorb water and minerals from the soil. 3. The roots store food. |
| List the two functions of stems | 1. The stem carries substances between the plant roots and leaves. 2. The stem provides support for the plant and holds up the leaves so they are exposed to the sun. |
| Describe basic function of leaves | Leaves capture the sun’s energy and carry out the food-making process of photosynthesis |
| What is the difference between photosynthesis and cellular respiration? | Photosynthesis needs water, the sun and minerals in the soil, but cellular respiration just needs food to make energy |
| The three ways a seed can be dispersed | 1. Some seeds passed through an animal’s digestive system. 2. Some seeds attach to fur or clothing 3. Wind and water also disperse seeds. |
| Label the basic parts of a flower | (Write/see handout) |
| Describe what each part of the flower does | See notes |
