Apoplast Pathway

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.

Define the terms

Apoplast and symplast pathway

Q.

What are casparian strips?

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.

Q.

Some carrier proteins allow two types of molecules to cross the membrane in the same direction. This type of transport is called

1. Uniport

2. Symport

3. Antiport

4. Aquaporins

Q.

How are the minerals absorbed by the plants?

Q. A botanist discovered a mutant plant that was unable to form functional Casparian strips. This plant would be

1. unable to transport water or solutes to the leaves.
2. unable to use its sugar as a sugar sink.
3. able to exert greater root pressure than the normal plant.
4. unable to control amounts of water and solutes it absorbs.

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

Q. In apoplast pathway, water moves through

1. cell wall

Q. Casparian strips interrupt the

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

Q.

Which pathway is faster Apoplast and Symplast?

Q.

3. both apoplastic and symplastic
4. none of these

Q. Explain the symplastic movement and apoplastic movement of water in the cell.

Q. Casparian strips interrupt the

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

Q. Assertion :During apoplastic movement of water, water travels through the cells and their cytoplasm. Reason: The symplastic movement of water occurs exclusively through the intercellular spaces and the walls of the cells.

1. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
2. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
3. Assertion is correct but Reason is incorrect
4. Both Assertion and Reason are incorrect
