Question

Give reasons for

(a) Intercellular spaces are absent in sclerenchyma tissues
(b) We get a crunchy and granular feeling, when we chew pear fruit.
(c) Branches to a tree move and bend freely in high wind velocity
(d) It is difficult to pull out the husk of a coconut tree
​

Answer 1

Answer:

Explanation:

Answer:

1. Intercellular spaces are absent in sclerenchyma tissues as these tissues are hard fibrous fibres which protect the plant from wear and tear. These are present in husk of coconut.
2. We get a crunchy and granular feeling, when we chew pear fruit because of the presence of sclerenchyma. These tissues are hard and provides skeletal support to fruits like pear.
3. Branches to a tree move and bend freely in high wind velocity but do not tear due to the presence of collenchyma tissue. These tissue provide intense flexibility to plants as they do not have a hard skeleton unlike animals.
4. It is difficult to pull out the husk of a coconut tree as said earlier that it is made of hard fibrous sclerenchyma tissue which is joined via lignin and it is so strong that it is very hard to pull the husk of coconut as well as coconut tree.

Answer 2

Answer:

Explanation:

Answer:

Intercellular spaces are absent in sclerenchyma tissues as these tissues are hard fibrous fibres which protect the plant from wear and tear. These are present in husk of coconut.

We get a crunchy and granular feeling, when we chew pear fruit because of the presence of sclerenchyma. These tissues are hard and provides skeletal support to fruits like pear.

Branches to a tree move and bend freely in high wind velocity but do not tear due to the presence of collenchyma tissue. These tissue provide intense flexibility to plants as they do not have a hard skeleton unlike animals.

It is difficult to pull out the husk of a coconut tree as said earlier that it is made of hard fibrous sclerenchyma tissue which is joined via lignin and it is so strong that it is very hard to pull the husk of coconut as well as coconut tree.
