Question
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.
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.
Answer: Option D
:
D
Most of the water flow in the roots occurs via the apoplast since the cortical cells are loosely packed and hence offer no resistance to water movement. But movement through the endodermis layer alone is symplastic.
