Plant Tissue Types and Functions

The video tutorial explains permanent tissues in plants, dividing them into simple and complex types. Simple permanent tissues are further classified into parenchyma, collenchyma, and sclerenchyma. Parenchyma consists of living cells with thin walls, providing support and food storage. Collenchyma has living, elongated cells with thickened corners, offering mechanical support and flexibility. Sclerenchyma comprises dead cells with thickened walls due to lignin, providing strength and rigidity to plant parts.

What are the two main types of permanent tissues?

• Living and dead

• Parenchyma and sclerenchyma

• Simple and complex

• Thick and thin

Which type of simple permanent tissue consists of unspecialized cells with thin cell walls?

• Xylem

• Parenchyma

• Sclerenchyma

• Collenchyma

What is a key function of parenchyma tissue?

• Storing food

• Transporting water

• Protecting seeds

• Providing flexibility

Which tissue is characterized by living cells that are elongated and thickened at the corners?

• Phloem

• Parenchyma

• Sclerenchyma

• Collenchyma

Where is collenchyma tissue commonly found in plants?

• Around the seeds

• In the flowers

• In the roots

• Below the epidermis in leaf stalks

What is a characteristic feature of sclerenchyma cells?

• They have thin cell walls

• They are living and flexible

• They store water

• They are dead and have thickened walls

Which substance is responsible for the thickened walls in sclerenchyma cells?

• Pectin

• Cellulose

• Chitin

• Lignin

In which parts of the plant is sclerenchyma tissue typically found?

• In the petals and fruits

• In the stems and veins of leaves

• In the roots and seeds

• In the roots and flowers
