Question

What happens when an animal cell is placed in a very dilute external medium ? Why ?

Answer 1

Osmosis

1. It is the movement of water from the area of its higher concentration to the area of its lower concentration through a semipermeable membrane.

Explanation:

1. When an animal cell is placed in a very diluted external medium, it gains water by the process of osmosis as the outside environment has a higher concentration of water than the inside environment of the cell.
2. The cell gains water through the process of osmosis. As a result, the cell swells up and can sometimes burst as animal cells do not have cell walls.
