Question

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

a
mitochondria
b
centrioles
c
cell walls
d
chloroplasts

Answer 1

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

**a. mitochondria**

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

The other options can be clarified as follows:
- **b. centrioles** are primarily found in animal cells and are involved in cell division.
- **c. cell walls** are present in plant cells (and some fungi and bacteria) but not in animal cells.
- **d. chloroplasts** are found only in plant cells and some protists, where they are involved in photosynthesis.

So, the correct answer is **a. mitochondria**.
