Answer:1.Yes plants take in carbon dioxide for "air" they need water to keep hydrated sunlight helps it make food.
2.Then the entire process of photosynthesis would crash. If no carbon dioxide the plant would not be able to breath and die, No water and it dies of thrist and no sunlight and the plant shivers and dies.
7. b and 8. c i attached the photo for u to see how i did it
Answer: Photosynthesis is a process through which green plants prepare their food by using carbon dioxide and water as reactants in the presence of sunlight energy. The food produced in the form of carbohydrate. Respiration is the process in which the biochemical oxidation of the food occurs.
Explanation:
The plant structures like leaves are specialized for performing the process of photosynthesis. These leaves have chlorophyll pigment which traps the light energy from sun which is required for splitting the molecules of water in the process of photosynthesis. Respiration occurs through stomata in leaves. But it also occurs in stems through lenticels and in specialized roots called pneumatophores via tiny pores.
