Question

Which of the following structures are found in plants but not in animals? Select all that apply.

Answer 1

Answer: The correct answer is Cell wall and Chloroplast.

Cell wall is a protective layer around plasma membrane in the plant cells, which is mostly composed of cellulose ( a complex carbohydrate). It provides structural support, strength, protection, and appropriate shape to the cell.

Chloroplast is a specialized membrane bound organelle, which is the site for the synthesis of food ( through photosynthesis) in green plants. It contains a green pigment called chlorophyll, which helps in the absorption of light energy through a series of chemical reactions and convert it into chemical energy in the form of ATP and NADPH. This eventually helps in the formation of food in the form of a carbohydrate ( glucose) in plants.

Thus, chloroplast and cell wall are the two structures, which are found in plants but not in animals.
