Which of the following statement is FALSE?
|
|
Water moves through Casparian strip
|
|
|
Root hairs are composed of single epidermal cells

|
Nodules containing bacteria enable plants to increase their absorption of nitrogen

|
Water travels along the cells of the cortex but must move through the cytoplasm of endodermal cells.
|
Explanation:
Detailed explanation-1: -The Casparian strip acts as a water-impermeable material that binds to the plasma membrane of the endodermal cells.
Detailed explanation-2: -At the endodermis the continuity of the pathway is broken due to casparian strips that prevent the water and the solutes from entering the space between the cell membrane and the cell wall of the cells forming the endodermis. So, the correct answer is Both statements are correct.
Detailed explanation-3: -Casparian strips form a barrier to the apoplastic flux, forcing ions to pass through the selectively permeable plasma membrane into the cytoplasm, rather than move along the cell wall.
