Question

Carbohydrates, the most abundant biomolecules on earth are produced by

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

Answer 1

The correct option is A Some bacteria, algae and green plants

Carbohydrate synthesis occurs through photosynthesis Chloroplasts are the green plastids which occur in all the green parts of the plants. They are the actual site of photosynthesis.

Cyanobacteria and other photosynthetic bacteria do not possess chloroplasts. However, the photosynthetic pigments of these organisms are located on thylakoids which lie freely in the cytoplasm.

The algae also contain the chloroplasts to perform the photosynthesis.

Fungi are either saprophytic, symbiotic or parasitic organisms. Viruses are parasitic.

Hence, the correct answer is 'Some bacteria, algae and green plants'.
