All living organisms use energy. they also grow and reproduce. what is another characteristic of all living organisms?
a. all living organisms must consume food in order to acquire nutrition.
b. all living organisms can produce glucose through photosynthesis.
c. all living organisms are composed of one or more cells.
d. all living organisms consist of many cells with specialized organelles.

C is the best answer. It is a component of the cell theory which states that all living things are composed of one or more cells.

All organisms are made of one or more cells, from bacteria and amoeba which consist of as few  as one cell to the human body which is made of as many as a trillion cells.

Cells are critical to the study of life and are usually referred to as the building blocks of life. All cells contain the following:

1. Lipid bilayer boundary called the plasma membrane.

2. Cytoplasm

3. DNA

4. Ribosomes for the synthesis of protein.
