Closer Look at an Organelles
Mitochondrion
Centriole
Vesicle
Cytoplasm
Golgi Body
Lysosome
Flagellum
Cell Membrane
Smooth Endoplasmic Reticulum
Ribosome
Nucleus
Rough Endoplasmic Reticulum
Cell Membrane
Protective layer surrounding the cell
Allows entry and exit of certain molecules
Acts a boundary for water in cell
Mitochondrion
Double walled organelleLarge surface areaSite of energy production
Sugar + Oxygen Water + Carbon Dioxide + Energy
Nucleus
Control Center of the CellContains the DNA
(deoxyribonucleic acid)Tells the cell how to build
proteinsControls cellular reproduction
Endoplasmic Reticulum
Transports chemicals between cells and within cells
Provides a large surface area for the organization of chemical reactions and synthesis
Smooth (no ribosomes)Rough (have ribosomes)
Golgi Body
Modifies chemicals to make them functional
Secretes chemicals in tiny vesicles
Stores chemicals May produce endoplasmic
reticulum
Cytoplasm
Fluid in the cell “salty” water full of all the chemicals
and electrolytes needed for cell function
