Question

Carbohydrates most abundant biomolecules on earth, are produced by :

• A. All bacteria, fungi and algae
• B. Fungi, algae and green plant cells
• C. Some bacteria, algae and green plant cells
• D. Viruses, fungi and bacteria

Answer 1

Answer: (C)

Some bacteria, algae and green plant cells

Answer 2

Carbohydrates, including cellulose, starch, glycogen, glucose, fructose, and others, constitute the most prevalent biomolecules on Earth. These carbohydrates are generated through photosynthesis, a process that involves the reduction of atmospheric carbon dioxide using light energy. Photosynthesis is primarily carried out by green plants, including aquatic algae, which convert carbon dioxide into carbohydrates. While some bacteria can also perform photosynthesis, their process differs in that they rely on chemical energy instead of light energy and do not produce oxygen as a byproduct, in contrast to the photosynthesis occurring in green plants.

So, the correct option is (C): Some bacteria, algae and green plant cells
