Current Question (ID: 12632)

Question:

Which of the following cell organelle is absent in prokaryotic cell?

Options:

1. Ribosome
2. Lysosome
3. Mitochondria
4. 2 and 3 both

Solution:

Prokaryotic cells are structurally simpler than eukaryotic cells and lack membrane-bound organelles such as the nucleus, mitochondria, and lysosomes. Ribosomes are present in both prokaryotic and eukaryotic cells and are responsible for protein synthesis. Lysosomes are membrane-bound organelles found only in eukaryotic cells, and contain enzymes that break down and recycle cellular waste. Mitochondria are also membrane-bound organelles found only in eukaryotic cells, and are responsible for generating energy in the form of ATP through the process of cellular respiration.
