What else can I help you with?
What specific characteristics would you look for under a microscope to visualize and identify meiotic cells at metaphase I?
To visualize and identify meiotic cells at metaphase I under a microscope, you would look for characteristics such as condensed chromosomes arranged in homologous pairs, the presence of a visible cell membrane, and the formation of the spindle apparatus. These features are key indicators of cells undergoing meiosis at metaphase I.
How are we able to see cells under a microscope?
Cells can be seen under a microscope because they are transparent and the microscope uses lenses to magnify and focus light on the cells, making them visible to the human eye.
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.
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.
What magnification is needed to see cells clearly under a microscope?
The magnification needed to see cells clearly under a microscope is typically around 400x to 1000x.
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?

Cells under 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.
What level of magnification is required to observe blood cells under a microscope?
To observe blood cells under a microscope, a magnification level of at least 400x is typically required.
