(in relation to the cell)
BODY STRUCTURE/ ORGAN functionally similar to and why?
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


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 the nucleus is not actually always in the center of the cell this is due to the presence of the vacuole. Storage of hereditary material, the genes in the form of long and thin DNA stands, referred to as chromatin. Storage of proteins and RNA in the nucleolus.

- Can be found in plant cells, animal cells and bacteria cells. - Eukaryotic call has only one nucleus. However, some eukaryotic cells are enucleate cells (without nucleus), example are red blood cells. - Nucleus is a site for the transcription in which messenger RNA are produced for the protein synthesis. - Exchange of hereditary molecules DNA and RNA between the rests of the cell. - During the cell division, chromatins are arranged into chromosomes in the nucleus. Production of ribosomes in the nucleolus.

Brain, because it acts as the control center of our body.
- Proteins (Soluble Proteins including Enzymes)
- Carbohydrates, Inorganic Salts, Lipids, and Lipoidal Substances are found. - The plasmogel part of the cytoplasm is capable of absorbing water and removing it, according to the cells need. - An organized system of fibers can be observed by specific staining techniques. Found all around inside the cell consists of water or H2O.

- The site of many biochemical reactions that is vital and crucial for maintaining life. - The cytoplasm is the place where the cell expands and growth of the cell takes place. - The cytoskeleton of the cytoplasm provides shape to the cell and it also facilitates movement. - It also aids in the movement of the different cellular elements. - The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Found in animal, plant, bacterial and fungal cells.

- The enzymes in the cytoplasm metabolize the macromolecules into small parts, so that it can be easily available for the other cellular organelles like mitochondria. - The cytoplasm is a means of transport...
