Plant Tissues: Simple Permanent Tissues and Their Functions

The video tutorial explores plant tissues, focusing on the rapid growth of bamboo due to cell division and elongation. It introduces permanent tissues, explaining differentiation and the types of simple permanent tissues: parenchyma, collenchyma, and sclerenchyma. Parenchyma is abundant and aids in food storage, while collenchyma provides flexibility, and sclerenchyma offers mechanical strength. The session concludes with a preview of complex permanent tissues to be covered in the next session.

What is the primary reason for the rapid growth of bamboo plants?

• Increased sunlight exposure

• High water absorption

• Cell division and elongation

• Nutrient-rich soil

What is the main function of parenchyma tissue in plants?

• Transporting water

• Facilitating gas exchange

• Storing food and providing support

• Providing mechanical strength

Which type of parenchyma tissue contains chlorophyll?

• Collenchyma

• Sclerenchyma

• Chlorenchyma

• Aerenchyma

What is the role of aerenchyma in aquatic plants?

• Facilitating photosynthesis

• Providing nutrients

• Strengthening the plant

• Trapping air for buoyancy

How does collenchyma tissue benefit young plants?

• By providing flexibility and support

• By conducting photosynthesis

• By hardening the plant structure

• By storing water

What characteristic of sclerenchyma makes it strong?

• Air cavities in cells

• Elasticity of cells

• Presence of chlorophyll

• Thickened, dead cells

Which tissue type is responsible for the mechanical strength of coconut shells?

• Sclerenchyma

• Parenchyma

• Aerenchyma

• Collenchyma
