Question

from where do plants obtain the initial carbon atoms that will be used in photosynthesis to make glucose a G3P B carbon dioxide c water D sunlight

Answer 1

Plants obtain the initial carbon atoms used in photosynthesis to make glucose from **B) carbon dioxide**. During the process of photosynthesis, plants take in carbon dioxide from the air through small openings in their leaves called stomata. This carbon dioxide is then converted into glucose through a series of reactions known as the Calvin cycle.
