In plant cells thin boundaryof vacuole is called tonoplast . It is just like cell membrane . It is visible by electron microscope .
The thin boundary of a vacuole, known as the tonoplast, may or may not be visible under a light microscope depending on the staining used, the type of vacuole, and the resolution of the microscope. In most cases, you would need an electron microscope to clearly visualize the tonoplast.
tonoplast
by applying a voltage across the boundary of two semi-conductors electrons are forces to travel across the boundary. This boundary has a voltage drop and the electrons are required to lose a discrete amount of energy in crossing it. In the case of the light emitting diode, it is a energy in the range of visible light.
A specific type of vacuole, called a contractile vacuole expels excess water from many fresh water protists.
its a vacuole
Tonoplast is the outer covering of vacuole
Cell wall, nucleus and chloroplasts can be seen with a compound light microscope under a total magnification of 400 X. The chloroplasts are self pigmented hence visible. Cell wall and nucleus being very dense are also visible without staining.
Vacuole is compared to a continent
1897 by Camillio Vacuole.
A vacuole holds water and salts.
The Vacuole Digests Wastes
No, it is not a vacuole membrane. A vacuole is a membrane bound sac with a single membrane called the tonoplast. The solution with in the vacuole is called cell sap which is a combination of organic and inorganic materials. I hope this helps, Dr. Hsiftl
