A cell is the smallest living unit of an organism.
All cells have three things in common
Any cell type is acceptable.
All cells have a cell membrane that separates the inside and outside of the cell
cytoplasmic, jelly-like liquid
DNA, the genetic material of cells.
There are two main categories of cells.
The first category is eukaryotic cells. you have an organelle
Includes core and other special parts.
Eukaryotic cells are higher and more complex cells
As seen in plants and animals.
The second category is prokaryotic cells.
They do not have a nucleus or membrane-enclosed organelles.
It has genetic material, but it is not contained in the cell nucleus. Prokaryotic cells
are always unicellular.
or single-celled organisms such as bacteria.
So what is an organelle?
Organelle means "small organ".
Organelles are specialized parts of cells that have specific tasks to perform.
Let's start with the cell's control center, the nucleus.
The nucleus contains DNA or genetic material. DNA tells the cell what to do
and how to do it.
Chromatin is the complex, stretched form of DNA found in the nuclear envelope.
when the cell is ready to divide
DNA is condensed into structures known as chromosomes.
The nucleus also contains the nucleolus
This is the structure that makes up the ribosome.
After the ribosome leaves the nucleus
They perform an important task of "synthesis".
Or manufacturing, protein. Outside the nucleus are ribosomes and the rest of the
organelles
It floats in the cytoplasm, a jelly-like substance.
Ribosomes move freely in the cytoplasm
