Answer to Question #176606 in Cell Biology for Johannes Steven

Question

All cells exist in life. Discuss. (50)

Answer 1

All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures.

Cells provide six main functions. They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction. Therefore, cells are the basic units of all living things and without them, an organism cannot survive.
