COMPARATIVE ANALYSIS OF THE DIFFERENT CELLULAR STRUCTURES
CELLULAR STRUCTURES
COMPOSITION
(Biomolecule)
LOCATION
(in relation to the cell)
NUMBER and DISTRIBUTION
PRESENCE/ABSENCE IN ORGANISMS
PROCESSES INVOLVED
(functions)
BODY STRUCTURE/ ORGAN functionally similar to and why?
CELL MEMBRANE
Glycoprotein
Phospholipids
Cholesterol
Glycolipids
Peripheral protein
Integral protein
Structural Protein
Receptor Protein
Transport Protein
Outer Side of the Cell
- Maintains the physical integrity of the cell.
- Forms a barrier between the inside of the cell and the environment outside the cell.
Animal Cell, Plant Cell, Prokaryotic cell and fungal cells have cell membrane.
- Physically separates the intracellular components.
- Protects the cell from some harmful chemicals in its external environment.
Skin, because they somehow practice both functions as the protector, transportation and the form of human body.
CELL WALL
Carbohydrates
Proteins
Fats
Water
Mineral

Outer Layer part of the Cell
1 Cell Wall
- Gives a cell a definite shape and structure.
- Provides structural support.
- Protection against infection and mechanical stress.
- Separates interior of the cell from the outer environment.

- Plant Cells, Fungal Cells and bacteria have cell wall.
- Protozoans and animals do not have cell wall.
- Maintains the integrity of the genes which regulates the gene expression, in turn regulating the activities of the cell. Therefore, the nucleus is also known as the control center of the cell.
- Enables transport of substances and information from the cell insides to the exterior and vice versa.
- Helps in osmotic-regulation.
Same as Cell Membrane it is similar to skin because it acts as the protector and the shape or form of the human body.
NUCLEUS
- Consists of nuclear membrane, nucleoplasm, nucleolus and chromosomes.
- Lipids and Proteins.
In animal cells the nucleus is usually in the middle of the cell where as in plant cells
