Explanation / Answer

Que 1

Ans:

The following structure are found in both prokaryotic and eukaryotic cells except: a. mitochondrion.

Explanation:

- Both prokaryotic and eukaryotic cells contain structures such as ribosome, plasma membrane and cytosol.

- Prokaryotic cells lack membrane bound organelles such as mitochondria, chloroplasts etc.

- Eukaryotic cells posses membrane bound organelles such as mitochondria, chloroplasts, golgi appartaus, endoplasmic reticulum.

- Hence, correct option is: a. mitochondrion.
