Functions - Cellular Envelope

Oscillin Layer~ Helps the cell with it's movement (gliding.)



S layer~ Helps with the growth, maintenance of cell, enzyme display, and interaction with the host and its immune system.


Outer Membrane~ Protects cell from a harsh environment on the outside.


Periplasmic Space~ It is the gel-like mix that is in the inner cytoplasmic membrane.


Peptidoglycan~ Helps maintain the shape of the cell and counter acts osmotic pressure of bacterial protoplast.


Inner Membrane~ Helps create more space so that it can perform cellular respiration.


Cytoplasm~ It is a jelly like liquid that helps keep all organelles in place.

Functions - Inner Cell

Lipid Droplet~ A spherical droplet that is composed of lipids and proteins that is used to store fat.


Nucleoid~ Keeps hold of genetic information.


Protein Granule~ Grains of protein providing protein throughout the cell.


Ribosome~ Synthesizes protein chains from amino acid molecules.


Photosynthetic Lamellae~ A thin layer that helps the membrane strengthen it's structure.


Cyanosomes~ This is responsible for 95% of energy transfer.


Plasma Membrane~ Surrounds the entire cell that controls the movement of substances into and out of the cell.


Cell Wall~Helps with structural support, protection, and filtering.


Gelatinous Coat~ An exterior fibrin gel protecting the cel from injuries.
