Major Organelles and their functions

Cell Membrane

The cell membrane controls....


Cell to cell recognition---carbohydrates


Communication---proteins


Permeability---lipid bilayer or transport proteins


Nutrients (like o2)---lipid bilayer


Waste (like o2)---lipid bilayer


Ions, glucose, etc.---transport proteins


Water Balance---lipid bilayer

Nucleus

Controls the cell


Contains most of the genes that control the cell


DNA is organized along with proteins forming chromatin that gives origin to chromosomes

Ribosomes

The sites where the cell assembles the proteins


can be bound to the ER (endoplasmic reticulum) or be free in the cytoplasm

Smooth Endoplasmic Reticulum

Synthesis of fatty acids, phospholipids, steriods, etc.

Rough Endoplasmic Reticulum

Synthesis of protein


Membrane factory


Golgi Apparatus

Center of Manufacturing, warehousing, sorting, and shipping.


(IN) Cis face- receives the vesicles from the ER


(EXIT) Trans face- sends the vesicles to the rest of the cells

Lysosomes

Digest proteins, fats, polysaccharides, nucleic acids


These enzymes work particularly better in an acidic environment


Many cells die when the lysosomes burst at the same time


(Recycling center of the cells)

Vacuoles

Food Vacuoles- fuse with lysosomes for digestion


Contractile Vacuoles- pump out the excess of water


Central Vacuoles- storage of organic compounds, ions, pigments, poisons, wastes, water, etc.

Mitochondria

The sites of cellular respiration, process that generates ATP by extracting energy from sugars, fats, and other fuels with the help of oxygen


Have small amounts of DNA for the synthesis of their own proteins

Chloroplasts

Found in only plants


Sites of photosynthesis


Convert solar energy into chemical energy by absorbing sunlight and using it to fuel the synthesis of organic compounds from carbon dioxide and water


Also have small amounts of DNA for the synthesis of their own proteins
