Detailed explanation-1: -an electromagnet. A microscope (micro-means small and-scope means to see or view) is used to view too small things to be seen by the eye. Plant cells are not seen by the naked eye because it is too small so a microscope is needed to study its structure.

Detailed explanation-2: -Compound microscopes magnify the tiny detail and structure of plant cells, bone marrow and blood cells, single-celled creatures like amoebas, and much more.

Detailed explanation-3: -Place the glass slide onto the stage. Be careful pushing it under the clips that the cover slide doesn’t move or crack. Turn the coarse focus knob slowly until you are able to see the cells. Turn the fine focus knob slowly until the cells are in focus and you can see them clearly.

Detailed explanation-4: -A microscope is an optical instrument used to observe objects that are invisible to the naked eye. It is used to observe and study cells.

Detailed explanation-5: -A number of stains can be used, including iodine solutions (iodine-potassium iodide, Lugol solution, Gram iodine), crystal violet, toluidine blue, and methylene blue. After 1 minute, rinse away the stain with tap water, add a coverslip, and observe the cells. Nuclei will be evident.
