Question

Name three groups of permanent tissue in plants by giving examples.​

Answer 1

Answer:

Parenchyma, collenchyma and sclerenchyma are three types of simple tissues. Xylem and phloem are types of complex tissues.

Answer 2

1. Simple

a. Parenchyma - soft parts of the plant such as cortex and pith

b. Collenchyma -  in the leaf stalks, below the epidermis etc

c. Sclerenchyma - in the leaf veins, hard coverings of the seeds and can also be found surrounding the vascular bundle.

2. Complex

a. Xylem - has xylem parenchyma, xylem fibres, trachieds, and vessels

b. Phloem - has sieve tubes, sieve plates, fibres, parenchyma and companion cells

3.Protective

a. Epidermis - is the outer layer of the plant body. Protects all parts.

b. Cork -  is light and does not catch fire easily. So,they are used as insulators and shock absorbers.

Hope this helps.
