There are many unicellular organisms. in addition, anything less than a cell is not alive. what do these two statements imply about cells. a. bacteria are single-cell organisms b. cells come from preexisting cells. c. most organisms are made up of cells. d. cells are the basic units if life.

The correct answer is option D (Cells are the basic units of life).

Explanation:

A cell is the basic unit of life which carries all the biological molecules inside the membrane to keep an organism alive. It is the structural and functional unit of life of which all living organisms are made of.

Living organisms can be single-celled or multi-celled as cells can attach,  interact with each other forming complex tissues dividing the responsibility to different tissues which further form organ and organ system of an organism like the digestive system. So, cells form the basic unit of biology.

Hence, option D (Cells are the basic units of life) is the correct answer.
