The presence of dew on the surface of leaves is due to

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.

Give differences:
$(1)$ Apoplast and Symplast pathways of movement of water in plants
$(2)$ Guttation and Transpiration

Select the correct option regarding the vascular tissues in plants.

Which of the following statements are true or false?
$I.$ The positive hydrostatic pressure is called turgor pressure.
$II.$ Wall pressure is exerted to prevent the increase of protoplasm size.
$III.$ Diffusion is more rapid in liquids than in gases.
$IV.$ Diffusion of water through a semi-permeable membrane is called imbibition.
$V.$ Osmosis is the movement of a substance,which takes place along a diffusion gradient.

Differentiate between diffusion and translocation in plants.
