Question 32

3 components of the Cell Theory

Answer 32

1. Cell is the basic unit of structure of all living things. 2. Cell is the basic unit of function of all living things. 3. Cells arise from other living cells.

Question 33

3 Exceptions to the Cell Theory

Answer 33

1. Viruses are not made of cells, but they do contain genetic information and reproduce inside another cell which is called the host cell. 2. The first cell could have arisen from pre-existing cells. (primordial soup of elements led to first cell) 3. Mitochondria and chloroplasts are organelles that contain their own genetic material and can reproduce independently of the rest of the cell.
