Question

Question 1 What structure is required for an organism to be classified as a photoautotroph?

Answer 1

Answer: The structure is chloroplast.

Explanation: Photoautotrophs are organisms that can synthesize food using light energy and carbon dioxide via photosynthesis.

Photoautotroph is a combination of two words: photo which means light and autotroph which means an organism that can manufacture its own food.

A photoautotroph manufactures its own food in a process known as photosynthesis. Photosynthesis is a process by which plants manufacture organic foods such as glucose using light energy, carbon dioxide and water. This process takes place in the chloroplast. A chloroplast is an organelle found in plant cells that contains chlorophyll which is the pigment that absorbs the light used in photosynthesis.
