Cell Classification and Composition
There exist two fundamental classifications of cells as given below:.
1) Prokaryotic cells.
2) Eukaryotic cells The lack of a cell nucleus or other membrane-bound organelle separates prokaryotic cells from eukaryotic cells.
Prokaryotic cells are the smallest type of life, being smaller than eukaryotic cells.
Typically, the study of the eukaryotic cel.

Eukaryotic Cells
Eukaryotic cells can either be unicellular or multicellular and include plant, animal, protozoa, and fungi cells, where all contain organelles with different sizes and shapes.
These specific cells are composed of the organelles given below:

How does cytology differ from pathology?
Virtually all cells perform biochemical functions, generating and transmitting energy, and storing genetic data carried down to further generations of cells.
Cytology differs from its cousin, pathology, in that cytology concentrates on the structure, function and biochemistry of normal and abnormal living cells.

Nucleus
Nucleus functions as a genome and the genetic information storage for the cell, comprising all the DNA organized in the chromosome form.
It is surrounded by the nuclear envelope that includes the nuclear pores allowing for protein transportation between the inside and outside of the nucleus.
Also, this is the site for replication of DNA and transcr.

Prokaryotic Cells
Prokaryotic cells include Archaea and Bacteria and lack an enclosed cell nucleus.
These both reproduce through binary fission.
Bacteria, which is the most prominent type, have many various shapes, which include a primary rod and spherical-shaped.
Bacteria are classed as either gram-negative or gram-positive based on the cell wall composition.

What does cytology mean?
Cytology meaning is given as the study of cells as the fundamental units of living things.
The very earliest phase of cytology starts with the English scientist named Robert Hooke’s microscopic investigations of cork in the year 1665.
He noticed the dead cork cells and introduced the term “cell” to describe those.
