Question

All living cell of biological world must have (1) Cell wall (2) Mitochondria (3) Cytoplasm (4) Plasma membrane

Answer 1

All living cell of biological world must have

(1) Cell wall

• (2) Mitochondria

(3) Cytoplasm

(4) Plasma membrane

Answer 2

All living cell of biological world must have (2) Mitochondria

Explanation:

• The "Powerhouse of the cell" is Mitochondria. The metabolic activities of respiration and energy production take place in this organelle, which is found in great quantities in most cells.
• It has a double membrane with layers formed by folding the inner section inwards (cristae).
• A membrane-bound organelle present in the cytoplasm of eukaryotic cells is the mitochondrion (plural mitochondria).

Parts of Mitochondria

1. Nucleolus
2. Nucleus
3. Ribosomes
4. Vesicle
5. Rough endoplasmic reticulum (ER)
6. Golgi apparatus
7. Cytoskeleton
8. Smooth ER
9. Mitochondria and  
10. Vacuole.
