Which process in plants is supported by stomata present in the lower surface of leaves?
a.photosynthesis      b.transpiration     c.reproduction    d. (a) and (b)
EXPLAIN WHY? With the option 
 

Dear student,Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.. so option d is correct. Hope this information helps,Regards.
