Plant Cells and Tissues

The dead element present in the phloem is

• companion cells

• phloem fibres

• phloem parenchyma

• sieve tubes

In desert plants, rate of water loss gets reduced due to the presence of

• cuticle

• stomata

• lignin

• suberin

If the tip of sugarcane plant is removed from the field, even then it keeps on growing in length. It is due to the presence of

• cambium

• apical meristem

• lateral meristem

• intercalary meristem

Parenchyma cells are

• relatively unspecified and thin-walled

• thick walled and specialised

• lignified

• none of these

Flexibility in plants is due to

• collenchyma

• sclerenchyma

• parenchyma

• chlorenchyma

Cork cells are made impervious to water and gases by the presence of

• cellulose

• lipids

• suberin

• lignin

Survival of plants in terrestrial environment has been made possible by the presence of

• intercalary meristem

• conducting tissue

• apical meristem

• parenchymatous tissue
