Answer:
Large organisms have fewer cells than small organisms
Explanation: Smaller cells have more surface area for oxygen and nutrients
Larger organisms have smaller cells than small organisms. Large organisms are made up of many small cells such that there is an increase in the amount of surface area in comparison to volume. This gives the large organism a better chance at survival.
The cell theory states the structural organization of the organisms. According to the theory, cells vary in size depending on their function and type. Thus, option D is correct.
Cell theory was proposed to give the basis of the structural organization based on the cells. The cell has been considered a structural and functional unit of any organism.
The cells are the carriers of genetic material and are produced from pre-existing cells. Large or small animals irrespective of size are composed of cells.
The size and function of the cells depend on the type and from where the cell has originated. The cells can be as small as blood cells and large as nerve cells. This totally depends on the location and function.
Therefore, in option D. the cell size varies based on location and function.
