Difficulty Level:


Apoplast movement

Find the wrong one.

  1. Dependent on gradient
  2. Water movement is through mass flow
  3. The continuous stream of water gets tension when water is absorbed by root hairs
  4. Mass flow of water occurs due to adhesive and cohesive properties of water

Difficulty Level:


Symplastic system

Find the wrong one.

  1. System of interconnected protoplasts
  2. Involves path through plasmodesmata
  3. Water has to enter the cells through the cell membrane
  4. Above a potential gradient movement

Difficulty Level:


Symplastic movement is slower than apoplastic movement

  1. Because it involves cytoplasmic streaming always
  2. Molecule has to enter through the cell membrane
  3. Because it is down the gradient
  4. All of these

Most of the water flow in the roots occur via the………

  1. Apoplast
  2. Symplast
  3. Active transport
  4. Imbibition

Difficulty Level:


Most of the movement in roots through apoplast is due to

  1. Cortical cells are loosely packed and hence no resistance to water movement
  2. Endodermal cells are loosely packed and hence no resistance to water movement
  3. Pericycle cells are loosely packed and hence no resistance to water movement
  4. Medullary cells are loosely packed and hence no resistance to water movement

Difficulty Level:


Mycorrhiza

Find the incorrect statement.

  1. Symbiotic association of fungus with root system
  2. Fungal hyphae have a very large surface area that absorb mineral ions and water from the soil
  3. Hyphae can go to downwards in depth and cause absorption of much larger volume of soil that perhaps a root cannot do
  4. Roots provide sugar and S containing compounds to the mycorrhizae
