Biology · Secondary 3 · Hard · Osmosis
A yam tuber with a cavity filled with concentrated sucrose solution is placed in a beaker of distilled water. After 30 minutes, what happens to the level of sucrose solution in the capillary tube and why?
- It falls because water leaves the cavity by osmosis.
- It rises because water enters the cavity by osmosis.
- It stays the same because no net movement of water occurs.
- It rises because sucrose diffuses out into the beaker.
