I would think it would be false considering part of the virus you are trying to get immunity to is in a vaccine
The water, warmed by the sun, turns into vapor (evaporates), and passes out through thousands of tiny pores (stomata) mostly on the underside of the leaf surface. This is transpiration. It has two main functions: cooling the plant and pumping water and minerals to the leaves for photosynthesis.
Answer:
What do I do with this information? XD
Onion is an underground crop and it have no involvement in the photosynthesis. So it have no chloroplast in their cell.
Hope this helps!
