It is the Nucleous
The dark blue spot seen in the center of a cell is typically the nucleus, which contains the cell's genetic material (DNA). In histological staining, the nucleus often appears darker due to the binding of dyes to nucleic acids. This structure is crucial for regulating cell activities and ensuring proper cell function and reproduction.
The structures allow the cell to perform specific functions.
Robert Hooke is the scientist who observed the cells of an orchid leaf and noted a dark circular structure near the cell. He observed these structures in 1665 using a primitive microscope, which he called "cells."
the cell wall
it is the organ cell.
Cell structures that carry the genetic material that is copied and passed from generation to generation of cells are called chromosomes. Spindles are cell structures composed of microtubule fibers.
Methylene blue is commonly used in animal cells because it can highlight cell structures like the nucleus due to its affinity for nucleic acids. While it can also stain plant nuclei, the staining intensity and specificity may differ between plant and animal cells. Despite this, methylene blue's versatility in staining cellular structures makes it a useful tool in studying biological specimens across different organisms.

When a tomato cell is stained with methylene blue, organelles such as the nucleus, vacuoles, and possibly some smaller structures like mitochondria or chloroplasts may become visible under the microscope. Methylene blue tends to bind to nucleic acids and can highlight these structures within the cell.
You can get dark blue from (plain) blue by adding (a small amount of) black.
No. Dark blue is a dark blue color, but navy blue is contrasted with white.
When you added methylene blue to the living yeast cell, the methylene blue is actually a dye so you could see the cells, therefore, the yeast cell became blue. It is much the same with hair dye. If you have a bottle of blue hair dye, it will dye your hair blue.
Navy blue or just dark blue.
the addition of white. then the dark blue will become sky blue,which is a tint of dark blue.
