Answer 1

Answer:

Explanation

parenchyma

* It consists of thin walled living cells which have intercellular spaces between them and their cell wall is made of cellulose.

*It serves the functions of food storage, absorption,lateral conduction,photosynthesis,providing buoyancy,secretion etc...

collenchyma

*It consists of refractile non lignifies living cells which possess pectocellulose thickenings in specific areas of their walls.

*It provides mechanical strength as well as flexibility to yound dicot stems petioles and leaves.

*It often contains chloroplasts for photosynthesis.

sclerenchyma

*It consists of dead cells with hard and extremely thick secondary walls due to uniform deposition of lignin.

*Sclerenchyma is of two types fibres and sclereids.

*The fibres occur in all those parts where mechanical strength is required.

*Sclereids are found in fruit walls of nuts and seed coat of legumes.
