Question

If cells were immersed in salt water how would the cells undergoing mitosis be affected (hint: think about the process of mitosis)

Answer 1

Upon immersion in salt water, water will start to flow out of the cells since the water potential inside the cells will be greater. When this happens, the cells will shrink.

Answer 2

The mitosis process of the cell will be inhibited in the saline environment.

Due to the response to water and salt stress that occurs via ABA which increases the expression of ICK1 that interacts with CDKA and inhibits histone H1 kinase activity (a protein involved in chromatin formation during phase S of the interphase).

This phenomenon is applied to highlight in the living cell the existence of chromosomes at the interphase, thus demonstrating the permanence of the chromosomal structure.
