Question

Movement of water into the xylem from cortex of the root can be refered
1: Lignin is present in the casparian strips of the endodermis.
2: Water has to enter the symplast pathway at the endodermis.
3: Through apoplast pathway most of the water moves across the root cortex.
A. only 3.
B. only 2.
C. 2, and 3 only.
D. All.

Answer 1

Answer:

All is answer...............

Answer 2

From the given options (A) is the correct answer i.e.water moves through apoplast pathway across the cortex in root.

Explanation:

Water moves in root through two different pathways:- 1.  Apoplast  

                                                                                              2. Symplast

Apoplast is the movement of water across root cortex via cell membrane and intercellular spaces.

Symplast is the movement of water in root cortex via protoplasm.

                  As the endodermis of root has casparian thickening due to which water is unable to enter in the cell cytoplasm. hence, it follows apoplast pathway while moving from cortex to xylem.

Therefore, option A is right.
