Carbohydrates the most abundant biomolecules on earth, are produced by
Options
A.all bacteria, funfi and algae
B.fungi, algae and green plants cells
C.some bacteria, algae and green plant cell
D.viruses, fungi and bacteria
Solution
Some photosynthetic bacteria such as Rhodopseudomonas can prepare carbonhydrates. But during this type of food synthesis O2 does not evolved because in this case hydrogen donor is other than H2 O. Algae (green and blue-green) and all green plant cells prepare their food (caebohydrate) through photosynthesis. Here, hydrogen ions are donated by water molecules by the process of photolysis of water, ie, O2 is released during this type of food synthesis
