Answer 1

Concept Introduction: Onion has rectangular cells.

Explanation:

We have been Given: Shyam took a thin layer of onion peel with a drop of water on a glass slide. He placed a cover slip on it and observed the slide under a microscope. But he was unable to see the cells of the onion peel properly.

We have to Find:

I) Why was Shyam unable to see the cells of the onion peel?

II) Describe the cells, Shyam would have observed under the microscope if he had carried out the experiment correctly.

1. Shyam was unable to see the cells of the onion peel extracted because he didn't stain the peel with Saffranin Solution or Millon's Reagent. Anything that is to be observed under the microscope should be stained with a staining solution.
2. The observation would have been, he would have seen small rectangular cells with tiny round circular nucleus.

Final Answer:

1. Shyam was unable to see the cells of the onion peel extracted because he didn't stain the peel with Saffranin Solution or Millon's Reagent. Anything that is to be observed under the microscope should be stained with a staining solution.
2. The observation would have been, he would have seen small rectangular cells with tiny round circular nucleus.
