Which of the following organelles is enclosed in a single membrane?
Which of the following organelles is enclosed in a single membrane?
The correct option is B Lysosomes
The correct option is B.
Explanation of the correct option :
1. Lysosomes are sac-like entities budded off from the Golgi body which contain digestive enzymes.
2. Lysosomes are enclosed by a single membrane that helps to maintain an acidic environment within the cell.
Explanation of the incorrect options:
Option A :
1. Nucleus is the spherical structure located in the center of the cell.
2. Nucleus is surrounded by a double-layered nuclear membrane made up of lipids and proteins.
3. Nuclear membrane separates the nucleus from the cytoplasm and contains small pores called nuclear pores to exchange materials.
Option C :
1. Chloroplast is a double-layered membrane structure that consists of a green pigment called chlorophyll.
2. The outer membrane of the chloroplast is attached to the endoplasmic reticulum, and the inner membrane possesses protein.
Option D
1. Mitochondria are rod-shaped structures surrounded by a double-layered membrane.
2. The outer membrane is smooth and porous while the inner membrane is folded into finger-like projections called cristae which increase the surface area for metabolic activities.
Final answer: Lysosomes organelle is enclosed in a single membrane.
