- Prokaryotic cell – the
cell without a proper nuclear membrane where there is no boundary between
the nucleus and the cytoplasm. - Eukaryotic cell – The
cell with a proper nuclear membrane where there is a boundary between the
nucleus and the cytoplasm. - Nucleus
- Endoplasmic reticulum –
It is an organelle that may have ribosomes associated called rough
endoplasmic reticulum where protein synthesis takes place and ribosomes
may not be associated called smooth endoplasmic reticulum where lipid
synthesis takes place. - Golgi Bodies – It is a
channel-like unit that contains vesicles and it can engulf the synthesized
proteins and lipids in these vesicles and deliver them to different parts
of the cell. - Lysosomes – These are
the organelles where unwanted substances are degraded - Mitochondria – It forms
the powerhouse of the cell where ATP synthesis takes place. - Chloroplast – It is a
double membrane organelle found only in plants and helps in providing
coloration to the plants - Vacuoles – These are
the storage organelle that stores proteins and other substances..
The cell is the basic structural and functional unit of life. Without a cell, our existence is not possible. The cell has its own structural identity. Let’s understand the structure of the cell more closely. The cell can be divided into two types:
Every eukaryotic cell has three major parts namely:
This is an important part of the cell that contains genetic material in the form of DNA.
2. Cell membrane or plasma membrane
It is the outermost protective covering of the cell that protects the cell from external damage. Plants have an extra protective layer called a cell wall that maintains the rigidity of the cell, that is the reason why a plant’s cell has a proper shape.
3. Cytoplasm
This is the fluid part of the cell that contains several structural entities called organelles which define a proper function or structure. The organelles are:
