If humans had chloroplasts we would be able to theoretically photosynthesize and create our own energy source, thereby eliminating the need to eat. But I think if we did we wouldn't have evolved the way we did (we evolved to follow our food, to survive, basically). We'd probably be rooted to the ground somewhere, like a plant.

Can you find 8 chloroplasts in the cell of a humans skin?

No, human skin cells do not contain chloroplasts. Chloroplasts are found in plant cells and algae, where they are responsible for photosynthesis. Human skin cells do not photosynthesize and do not contain chloroplasts.


What would happen if you did not have chloroplasts?

Well humans do not have chloroplasts. Chloroplasts only show up in plant cells as chloroplasts are for obtaining energy from sunlight through photosynthesis. No animal is able to do this as chloroplasts are not present in animal cells.


Which part of a plant would you expect to find cells with chloroplasts?

Not in the leaves


Would you find chloroplasts in animal cells?

no


Would a plant cell die if it lost its chloroplasts?

No, there are several living cells in the plant without chloroplasts.


Which organelle would you find in plant cells but not in animal cells?

Chloropalsts. They are the ones who do the process of photosynthesis. An animal cell does not have them.


Where would you expected to find the cells with the most chloroplasts?

Leaves


Which cells would not have chloroplasts?

There are many cells. Every prokariyotic cells,animal cells,fungi cells and many protista lack them


What would happen to a plant cell with no chloroplasts?

There will be no photosynthesis.Plant will be dead.


Which part of a mango tree would contain cells with the greatest number of chloroplasts?

The leaves of a mango tree would contain cells with the greatest number of chloroplasts. This is because chloroplasts are responsible for photosynthesis, and leaves are the main site of photosynthesis in plants.


Can you introduce photosynthesis gene in human?

Yes. Photosynthetic organelles, i.e. chloroplasts, could be introduced to human cells and theoretically work. although there are a number of limitations; firstly the structure of human skin cells currently would not allow for sunlight to reach the chloroplasts humans would need to develop a layer of clear cells such as the epidermal cells found on plant leaves. Secondly, even if somehow human skin cells developed or were engineered to have these traits this would mean to procure enough light energy we'd have to go au natural if you get my drift ;) and finally even if we did manage to incorporate chloroplasts and other photosynthetic mechanisms into our cells the likely-hood is that the energy produced by photosynthesis would have little benefit and we would still need to consume a large quantity of calories to survive. The only animals which incorporate photosynthesis successfully, such as the Elysia chlorotica, seem to be largely stationary and so do not have the energy requirement that a human would. I guess the answer to your question is it can be done but there's not really much point to it :/


If you could add chloroplasts to animal cells how would it change their behavior?

They would be able to photosynthesise, which they are currently unable to do because they do not possess chloroplasts.
