Question

Which of the following organisms do not perform photosynthesis?

• A. Ferns
• B. Algae
• C. Cyanobacteria
• D. Bread Mould

Answer 1

The correct option is D Bread Mould

Organisms which contain the green pigment chlorophyll have the capability to produce their own food. In the given options, ferns and algae are green plants which perform photosynthesis to obtain their own food. Cyanobacteria also called blue-green algae can also synthesise their own food with the help of the pigment - chlorophyll a.
Bread mould is a fungus which grows on bread. Most fungi feed on dead and decaying matter, hence they are saprophytic. They do not contain chloroplast that is necessary for photosynthesis to occur.
