Explanation:

plasmolysis is the shrinkage of protoplast from the cell wall under the influence of a hypertonic solution.this can be observed by placing the fresh filament of spirogyra in a 10% solution of common salt.the cell undergoes exomosis.
Selective breeding is when a human or farmer in this case selects two plants or chickens with the best traits in order to get a good yield and quality for the products they are producing. I hope this helps!
