You can see parts of cells by microscopy.
A light microscope will reveal detail with a resolution down to about 0.2 micrometers. More detail becomes visible using various techniques, such as staining or phase contrast microscopy.
An electron microscope improves the resolution to about 2 nanometers. What is seen in an electron micrograph is the shadow left by heavy metal atoms in the stain, which has attached to cell structures.
It is the largest organelle in the cell.
Electron microscope
The cell wall is a part of a bacterial cell that provides structure and support.
This is something all viruses do in effect when they attack a cell and make the cell start producing new viruses as a part of their reproductive process. See the related question below about the Lytic Cycle which describes the steps in that process.
cytoplasm
The smaller part of the cell
The answer is not the thought of OBVIOUS answer, as when the nucleus of a cell was removed the cell continued functioning as if nothing had been done to it. The only effect was that the cell could not reproduce. See Bruce Lipton in the Biology of Belief. The cell works together.
the longest part of the cell cycle is Interphase
The cell wall of plant cells is the part which gives the cell sturdiness and rigidity.
Cell wall
the part of gthe cell which supports the animal cell is the cell membrane
With a less stronger microscope the nucleus ,cell membrane and cytoplasm are visible,but in plant cell cell wall and chlorophalast
