Answer:
A=even more of the cell than when it was in water
Answer:
When a red onion cell is placed in a 5% NaCl solution, the central vacuole will occupy
B) less of the cell than when it was in water
This is due to plasmolysis
Explanation:
Plasmolysis is the process in which there is a loss of water from cells when these are placed in a hypertonic solution. The protoplast and vacuole shrinks away from the cell wall.
Hypertonic solution is that which has higher concentration of solutes (low water concentration) as compared to inside the cell. As water moves from high conc. to low conc., it moves from inside the cell to outside. Thus, the vacuole pulls away from the cell when placed in a hypertonic solution (5% NaCl).
