Q. Consider the following statements regarding plant tissues:
1.Parenchyma cells are relatively unspecialized and possess thin cellulose cell walls.
2.Collenchyma tissue provides mechanical support and flexibility, allowing plant parts to bend without snapping.
3.Sclerenchyma is composed of living cells that provide buoyancy to aquatic plants.
How many of the statements given above are correct?
Answer: B
Notes:
Explanation:
- Statements 1 and 2 are correct.
- Statement 3 is incorrect: Sclerenchyma consists of dead cells with lignified walls (e.g., coconut husk). The tissue providing buoyancy in aquatic plants is a specialized parenchyma called Aerenchyma.
