Apoplast Pathway

Q. Identify the correct statement related to water movement in deeper layers of the root.
A. Apoplastic movement of water does not involve the crossing of the cell membrane.
B. Symplastic movement is aided by cytoplasmic streaming.
C. Most of the water movement in the root is through symplast.
D. Water movement through the root layers is ultimately symplastic in the endodermis.

1. A & B only

2. A & D only

3. A, B & D

4. B & C only

Q. Apoplastic movement of water occurs in plants through

1. intercellular spaces
2. plasmodesmata
3. both a and b
4. cell walls

Q. Apoplast pathway is faster than the symplast pathway because

1. it is composed of living parts of the plant
2. it is blocked at the endodermis by the casparian strip
3. water movement occurs by osmosis
4. water movement occurs by passive diffusion

Q. In apoplast pathway, water moves through

1. cell wall
2. plasma membrane
3. plasmodesmata
4. cytoplasm

Q. Casparian strips interrupt the

1. apoplast pathway
2. symplast pathway
3. mycorrhizal absorption
4. movement of water through plasmodesmata

Q. The conduction of water from root hair to xylem of root is

1. symplastic
2. none of these
3. apoplastic
4. both apoplastic and symplastic

Q. Apoplastic movement of water occurs in plants through

1. intercellular spaces and cell walls
2. plasmodesmata
3. casparian strips
4. cytoplasm and plasmodesmata

Q.

How are the minerals absorbed by the plants?

Q. What are apoplast and symplast?
