Matching Cell Organelles to Functions
Organelle-Function Correspondence
To correctly match the structures in List-I with their functions in List-II, consider the primary role of each organelle:
- Mitochondria (A) are primarily responsible for generating ATP through cellular respiration.
- Cytoskeleton (B) provides structural support, maintains cell shape, and aids in cell movement.
- Smooth Endoplasmic Reticulum (C) is involved in lipid synthesis, calcium storage, and detoxification, particularly prominent in liver cells.
- Vacuoles (D) function in storage (water, nutrients, waste) and, especially in plant cells, contribute to maintaining turgor pressure and cell enlargement.
