Xylem helps in the translocation of:

Differentiate between apoplast and symplast pathways of water movement. Which of these would need active transport?

Cells absorb water by

Correct the following statements:
$(a)$ Cells shrink in hypotonic solutions and swell in hypertonic solutions.
$(b)$ Imbibition is a special type of diffusion when water is absorbed by solids—colloids—causing them to increase in volume.
$(c)$ Most of the water flow in the roots occurs via the symplast.

In which direction does water move?

Choose true and false statements from the following and select the correct option from the set $(A-D)$ given below:
$I.$ Diffusion is an important process of transport in plants since it is the only means for gaseous movement within the plant body.
$II.$ In active transport,pumps are proteins that use energy to carry substances across the cell membrane against the concentration gradient.
$III.$ In facilitated diffusion,special proteins help hydrophilic substances to be transported across the membrane.
$IV.$ In diffusion,molecules move against the concentration gradient in a random manner.
$V.$ Facilitated diffusion is faster than active transport.
