Question

You prepare a slide to observe cells from an unknown specimen.Under the microscope you see that the cells are rectangular,have a freely permeable boundary part A and beneath it a selectively permeable part B. There is a dot-like structure C in the cells too.These cells form the protective tissue of the specimen.

Based on the above observations, draw a neat diagram of the cells and label the parts A,B and C.

please answer correctly i need it asap

Answer 1

Explanation:

Selective permeability is a property of cellular membranes that only allows certain molecules to enter or exit the cell. This is important for the cell to maintain its internal order irrespective of the changes to the environment. For example, water, ions, glucose and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity.
