Three Major Parts of the Cell

Encloses the cell and separates it from external environment. • Referred as fluid mosaic. • Selectively permeable.

The “control center” of the cell. • It houses the genetic material. • It has nucleolus, where the subunit of ribosomes are assembled.

A jelly-like substance (cytosol) which is mainly composed of water with dissolves substances. •This is where the other organelles are suspended dynamically.

Site for protein synthesis. • Free ribosome and Attached ribosomes. •Protein is important inside the cell.

Serves as the transport system of the cell (like a highway). • Two types of ER: • Smooth ER (SER) – without ribosomes; for lipid synthesis. • Rough ER (RER) – with ribosomes.

Involved in modifying, sorting, and packaging of macromolecules. • For delivery to another organelles.

Suicide sacs. • It play role in the destruction or repair of defective parts of the cell. • Exclusive for animal cells.

Storage sacs in the cells. • In animal cells use for storage of water and food others for excretion of waste materials. • In plant cells, it is very large. Mitochond

The “powerhouse of the cell”. • Site for cellular respiration. • It creates energy by breaking down food molecules. • Adenosine triphosphate (ATP) – a useable form of energy inside the cell.

Special organelles

Centrosome is found outside the nucleus which consist of two rod-shaped centrioles. • It is for the fiber division. spindle during cell

It serves as a framework for the cell.

• whip-like structure. • For locomotion.

hair-like structure • Cellular locomotion, movement of particles and filtration.

Are double-membrane organelles found in plants and photosynthetic protist.

Three Classifications of Plastids

are simple, single-celled (unicellular) organisms that lack a membrane- bound nucleus, mitochondria, and all other organelles.

are organisms with cells that contain membrane- bound nucleus and other membrane-bound organelles.

Two main groups:

Lysosomes also participate in a programmed cell death called______

is a semifluid solution composed of water, inorganic and organic molecules that are encased by the cell membrane. It is where all organelles are located and most of cellular activities take place.

can only be found in plants and algae. It is responsible for converting energy to chemical energy through the process of photosynthesis.

are hair-like projections that enables the cell to move. Cilia are much shorter than flagella, but they have similar construction.

are protein fibers that play a role in the movement of the cell and the organelles.

are protein fibers that provide support and strength to the cell.

are cylinders of protein molecules present in cytoplasm, centrioles, cilia, and flagella.

Archaea that can survive under extreme condition are called

are the extension of cell membrane used for attachment of enzymes that carry on metabolic activities.

is a layer of polysaccharides lying outside the cell wall. It functions as a receptor and protection to the cell.

are short, hair-like structures on the cell surface of prokaryotic cells. They can have a role in movement, but are more often involved in adherence to surfaces, which facilitates infection, and is a key virulence characteristic. Structure of a bacterial cell.
