Answered

Which of the following is a primary function of cells in living organisms?
A) To perform photosynthesis
B) To store genetic information
C) To transport nutrients across cell membranes
D) To provide structural support for tissues



Answer :

Answer: B) To store genetic information

Explanation: Cells are the basic unit of life in all living organisms. One of their primary functions is to store genetic information in the form of DNA (deoxyribonucleic acid). This genetic material contains the instructions needed for the development, functioning, growth, and reproduction of the organism. DNA is found in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells.

While other functions listed—such as performing photosynthesis (specific to plant cells), transporting nutrients, and providing structural support—are important, they are not primary functions of all cells. Storing genetic information is a universal function critical to the continuity of life.
