Diffusion is a major method of transport of materials in

• tall plants

• unicellular plants

• Multicellular plants

• Both (b) and (c)

Diffusion is not effective in

• solids

• liquids

• gases

• all of the above

Xylem fibres are made of –

• Parenchyma cells

• Collenchyma cells

• Sclerenchyma cells

• Aerenchyma cells

Which of the following do not take part in conduction?

• Tracheids

• Vessels

• Sieve tubes

• Fibres

Which of the phloem cells help in storage of food?

• Sieve tubes

• Companion cells

• Phloem parenchyma

• Phloem fibres

Absorption of water in plants take place by

• osmosis

• diffusion

• both (a) and (b)

• none of the above

Diffusion occurs when molecules move

• from lower concentration to higher concentration.

• from higher concentration to lower concentration through a membrane.

• from higher concentration to lower concentration.

• when energy is used.

If the xylem vessels of a plant are plugged

• the leaves will turn yellow

• no food will be made

• the plant will wilt (shrivel)

• the plant will continue to grow
