What is stomata?
Question:
What is stomata?
Green Plants:
Green plants are autotrophs that have a chlorophyll pigment in them to help in photosynthesis. The chlorophyll pigment takes up sunlight in the presence of other factors like water and minerals; it prepares food in the form of glucose. The glucose molecules then travel to distinct tissues of the body through the vascular system.
