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 them as A, B, C

Answer 1

Answer:

This is a plant cell.

A- Cell wall

B- Cell membrane

C- If there is only one dot-like structure, than it is a nucleus. If there is more than one, then it is a chloroplast (I think. It is most likely the nucleus.)

Explanation:

The Cell Wall is the wall that protects the plant cell. Plant cells are the only cells that have this.

The Cell membrane is a membrane surrounding all cells, and is selectively permeable.

And if C is the nucleus, then it is the brain of all cells. It contains DNA that is used to make all the parts of the cell function like they are supposed to.
