Question

Which of the following structures are typically present in both plant and animal cells?

a
chloroplasts
b
centrioles
c
cell walls
d
mitochondria

Answer 1

The structure that is typically present in both plant and animal cells is:

**d. mitochondria**

Mitochondria are the powerhouses of the cell and are found in both plant and animal cells.

The other structures listed are generally not found in both types of cells:
- **a. chloroplasts** are present only in plant cells.
- **b. centrioles** are generally found in animal cells (and some lower plant forms) but are not present in most higher plant cells.
- **c. cell walls** are found in plant cells (and fungi) but not in animal cells.
