What effect did staining the onion cells have on their appearance under the microscope?
Staining the onion cells allowed for better visualization of the cell structures. It added color to the cells, making them more distinct and easier to observe under the microscope. This made it easier to identify the different parts of the cells, such as the nucleus and cell wall.
Why are individual cells not visible under an electron microscope?
Individual cells are not visible under an electron microscope because the resolution of the microscope is not high enough to distinguish the borders of individual cells. The electron microscope's resolution is limited by the wavelength of electrons used, preventing the visualization of single cells. Cells can be seen collectively as tissues or structures under an electron microscope.
Why is it necessary to stain microbial specimen before viewing them under a microscope?
Staining microbial specimens allows for better visualization of their structures and morphology under a microscope. It increases the contrast between the cells and the background, making them easier to identify and study. Staining also helps to highlight specific features or organelles within the cells.
How can you identify erythrocytes by using microscope?
Erythrocytes, or red blood cells, can be identified under a microscope by their characteristic biconcave disk shape, lack of a nucleus, and pink/red coloration due to hemoglobin. They are typically smaller in size compared to other blood cells and appear uniform in shape when properly stained and viewed under high magnification.
What did Robert hooke discover under the microscope?
Robert Hooke discovered cells in plant tissue when he observed thin slices of cork under a microscope. His observation of cells marked the beginning of the field of cell biology.
Are plant cells less easy to observe and identify under a microscope than animal cells?
Maybe
Why do you use iodine to help make a slide for a microscope?
Iodine is used to stain cells on a microscope slide to make them more visible under the microscope. It helps to highlight specific structures within the cells, making them easier to study and identify.
Who was the first person identify cells?
Robert Hooke, an English scientist, was the first person to identify and describe cells. In 1665, he observed cork under a microscope and noticed compartments that he named "cells" due to their resemblance to small rooms in a monastery.
How can you identify parenchyma under microscope?
poo on it

What was the first kind of cell seen under a microscope?
Cork cells from plants were first observed under a microscope by Robert Hooke.
Which scientist is given credit for viewing cells under the microscope but not naming them cells?
Leeuvenhoek
