Plant tissue

The cells of cork are dead and have a chemical in their walls that makes them impervious to gases and water. The chemical is

• lignin

• suberin

• cutin

• wax

The flexibility in plants is due to a tissue called

• parenchyma

• chlorenchyma

• collenchyma

• sclerenchyma

Sieve tubes and companion cells are present in

• xylem

• phloem

• cambium

• cork

The size of the stem increases in the width due to

• apical

• intercalary

• lateral

• vascular bundle

Xylem and phloem are examples of

• epidermal tissue

• connective tissue

• protective tissue

• vascular tissue

A tissue whose cells are capable of dividing and re-dividing is called

• complex tissue

• permanent tissue

• connective tissue

• meristematic tissue

The upward conduction of water and minerals by

• phloem

• cambium

• xylem

• epidermis

The only dead cells in phloem

• companion

• sieve

• phloem fibres

• phloem parenchyma

Packaging tissue

• parenchyma

• collenchyma

• xylem

• phloem

The nuclei of meristematic cells are

• small

• large

• medium sized

• no nucleus
