Question

Focus your discussion on ONE of the following topics:

1. Describe at least 2 benefits and 2 drawbacks there might be for animal cells (including humans) to make their own food through photosynthesis.
2. Explain which cells, tissues, or organs should be modified to lead to successful photosynthesis in animals or humans. Discuss how these compare to a plant's leaves.
3. Describe the process of photosynthesis to explain at least 1 requirement for photosynthesis that would need to be considered for chloroplasts to function in an animal or a human.

Answer 1

Answer-

I am focusing on last topic-

Things responsible for photosynthesis are-

• Presence of chloroplast
• Presence of sunlight
• Presence of carbon dioxide
• Presence of efficient surface area for contact between chloroplast and sunlight.

Therefore the requirement that would need to be considered for efficient functioning of chloroplast in human cells is-

The presence of efficient and/or sufficient surface area for contact between chloroplasts and sunlight.

The plants will have patiently larger surface area for contact between chloroplasts and sunlight because they have large number of leaves which provides them great surface area. But animals did not have leaves and therefore if there skin is used for absorption of sunlight then it will have less absorption.

Moreover metabolic demands of animal cells or body is larger as compared to plants.
