Answer:
The answer is Sodium (Na+)
Explanation: The cell wall of the plant cells is composed mostly of cellulose, which is a polysaccharide composed mostly of carbon, hydrogen and oxygen, and it has a linear and complex configuration. On the other hand, the cell membrane is composed of phospholipids, in the configuration of lipid bilayer. Phospholipids are molecules that have a polar head (where phosphorus is found) and a hydrophobic (lipid) tail. Carbon and hydrogen are also found in non-polar or hydrophobic tails. Sodium on the other hand is an Ion (Na +) that is mainly dissolved in water, so it is expected to find it mostly in the lumen or outside the cell. Sodium plays an important role in the transport of some substances through the cell membrane, but their amounts cannot be very high, because of being very concentrated, this can cause plasmolysis or cell destruction
Answer:
Option C
Explanation:
Image for the question is attached here
Solution
It is given that the membrane is permeable to both salt and water.
Thus, water will form region of high concentration to the region having low salt concentration. The same applies to the movement of water molecule.
As we can see in the image, Side A has higher water concentration and side B has higher salt concentration.
Thus water will move from side A to side B and Salt will move from side B to side A.
Hence, option C is correct
