Question

Which part of the cell plant permits it to withstand very dilute external medium without bursting

Answer 1

Answer:

Explanation:

The Cell Wall prevents the plant cell from bursting when it is placed in a hypotonic solution , it takes up water by osmosis and starts to swell, but does not burst.

Answer 2

Though plant cell consists cell wall, its main function is to give the cell structural support and protection from physical damage. But it is often permeable. The next layer, the cell membrane is semipermeable or sometimes  selectively permeable which stops the external solute molecules to enter inside the cell and thus prevents the bursting of the plant cell in dilute external medium.

so It is the cell wall which protects the cell from bursting due to osmosis in dilute external medium.
