| Question | Answer |
|---|---|
| What is the main purpose of the roots? | to absorb and take up water and minerals from soil, to anchor the plant in the ground |
| Why do plants have root hairs? | to increase the surface area by which to absorb more water and minerals |
| What does the xylem carry? | water and minerals from the roots throughout the plant |
| What does the phloem carry? | food to all parts of the plant |
| Where is glucose made? | in the leaves/chloroplasts |
| What is the purpose of the guard cells? | to open and close the stomata |
| What is the stomata? | to allow water, carbon dioxide, and oxygen to enter and exit a leaf |
| What is the main function of the leaves? | to trap sunlight and make food through photosynthesis |
| What is the main function of the stems? | to allow movement of materials between roots and leaves and to support the branches leaves and flowers, may store water |
| Write the photosynthesis equation | 6 CO2 + 6 H2O + sunlight = C6H12O6 = 6 O2 |
| Write the photosynthesis equation in words | carbon dioxide + water = glucose + oxygen |
| What cell does photosynthesis happen in? | chloroplast |
| What time of day does photosynthesis take place? | daytime |
| What are the products needed for photosynthesis to happen? | water, sunlight, carbon dioxide |
| What are the end products of photosynthesis? | glucose, oxygen |
| What is the cellular respiration equation in words? | glucose + oxygen = carbon dioxide + water + energy |
| What is the cellular respiration equation? | C6H12O6 + 6 O2 = 6 CO2 + 6 H2O + ATP |
| Where does photosynthesis take place? | Chloroplast |
| Where does plant respiration take place? | Mitochondria |
| What are the end products of plant respiration? | carbon dioxide, water, energy |
| What are the starting products of photosynthesis? | carbon dioxide,water, sunlight |
| What are the starting products of plant respiration? | glucose and oxygen |
| When does plant respiration take place? | during the night |
| What part of a tree is used in making paper? | pulp |
