Which of the following is found in plant cells only?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Cell wall.
- Cell walls are unique to plant cells, providing essential structural support and protection.
- Composed primarily of cellulose, they give plant cells their rigidity and help maintain cell shape.
- Unlike animal cells, which only possess a flexible plasma membrane, plant cells have this rigid outer layer that withstands osmotic pressure and shields against physical damage and pathogens.
- While plant cells also contain other distinctive features such as chloroplasts for photosynthesis and large central vacuoles for storage and maintaining turgor pressure, the cell wall remains a defining characteristic exclusive to plant cells.
- This structure is crucial for the overall integrity and function of plant cells.
