Question

2 how do plants get the materials (the reactants) they need in order to perform photosynthesis? a water flows in through the stomata, oxygen flows in through the roots b glucose flows in through the roots, carbon dioxide flows in through the stomata c carbon dioxide flows in through the stomata, water flows in through the roots d oxygen flows in through the stomata, and water flows in through the roots 3 what happens to the products of photosynthesis? a oxygen is stored in the plant, while glucose is released into the atmosphere. b water flows out through the stomata, while glucose is stored in the plant. c carbon dioxide is released into the atmosphere, while water is stored by the plant. d glucose is stored in the plant, while oxygen is released in to the atmosphere. 4 the model represents the reaction that occurs when plants make sugar. what does x represent in this model? a air b light energy c oxygen gas d water

Explanation:

• Question 2:
• Photosynthesis reactants are \(CO_2\) and \(H_2O\). \(CO_2\) enters through stomata (tiny openings on leaves), and water is absorbed by roots.
• Question 3:
• Photosynthesis products are glucose (\(C_6H_{12}O_6\)) and \(O_2\). Glucose is stored (used for energy/storage), and \(O_2\) is released.
• Question 4:
• The photosynthesis equation is \(6CO_2 + 6H_2O+light energy

ightarrow C_6H_{12}O_6 + 6O_2\). X is light energy (drives the reaction).

Answer:

• Question 2: C. carbon dioxide flows in through the stomata, water flows in through the roots
• Question 3: D. Glucose is stored in the plant, while oxygen is released in to the atmosphere.
• Question 4: B. light energy
