Question

this picture shows photosynthesis taking place. when green plants are in sunlight, this is what happens: water plus carbon dioxide make glucose and oxygen. figure c look at figure c and then answer the following questions about photosynthesis. 1. does photosynthesis take place in the leaves or in the roots? 2. what two materials must a plant take in for photosynthesis? 3. what else is needed for photosynthesis? 4. where does the carbon dioxide gas come from? 5. what are the two things that photosynthesis makes? 6. what does a plant make as food? 7. where does water enter a plant? 8. where does carbon dioxide enter a plant? 9. where does oxygen leave a plant? 10. what living things use the oxygen?

Explanation:

1. Chlorophyll - containing cells in leaves are where photosynthesis occurs as they can capture light energy.
2. Water is absorbed by roots and carbon - dioxide enters through stomata on leaves.
3. Light energy is crucial to power the chemical reactions.
4. Carbon - dioxide is present in the air and enters plants through stomata.
5. Glucose is made as food and oxygen is a by - product.
6. Glucose is the food made by plants through photosynthesis.
7. Water enters a plant through its roots.
8. Carbon dioxide enters a plant through the stomata on the leaves.
9. Oxygen leaves a plant through the stomata on the leaves.
10. Most living organisms, including animals and humans, use oxygen for respiration.

Answer:

1. Leaves
2. Water and carbon dioxide
3. Light energy
4. The air
5. Glucose and oxygen
6. Glucose
7. Roots
8. Stomata on the leaves
9. Stomata on the leaves
10. Animals and humans (most living organisms)
