Question

question 14 (1 point) which of the following statements is part of the cell theory?

a cells are composed mostly of empty space.

b all cells are produced from existing cells.

c cells are generally large enough for the unaided eye to see.

d only animals are made up of cells.

Explanation:

Cell theory has three main parts: all living things are made of cells, cells are the basic unit of life, and all cells come from pre - existing cells. Option a is wrong as cells are not mostly empty space. Option c is wrong as most cells are too small to be seen with the unaided eye. Option d is wrong as both plants and animals (and other organisms) are made of cells. Option b matches the part of cell theory that all cells come from existing cells.

Answer:

b. All cells are produced from existing cells.
