1
Nucleus/Nucleolus Structure Function Cell Type
Double membrane (nuclear envelope) Function Control center of the cell Stores hereditary info (DNA) Makes RNA and protein Makes ribosomes (nucleolus) Cell Type Eukaryotic Cells Plant and Animal Cells
2
RIBOSOMES Structure Function Cell Type Made of proteins and RNA
No membrane Most numerous organelle Made in nucleus (specifically in nucleolus) Function Aids in protein synthesis Free ribosomes make proteins used by the cell Ribosomes on rER make proteins for export to other cells Cell Type Prokaryotic and Eukaryotic Cells Plant and Animal Cells
3
ROUGH ER Structure Function Cell Type
Internal membrane is a system of folded sacs and tunnels Has ribosomes Function Intracellular highway Molecules move from one part of cell to another to be exported out of cell Cell Type Eukaryotic Cells Plant and Animal Cells
4
SMOOTH ER Structure Function Cell Type
Internal membrane of systems of folded sacs and tunnels NO ribosomes Function Intracellular highway Storage area for proteins Cell Type Eukaryotic Cells Plant and Animal Cells
5
GOLGI APPARATUS Structure Function Cell Type
Stack of membranes or sacs filled with fluid Function Processing, packaging, and secreting organelle Helps with protein synthesis Cell Type Eukaryotic Cells Plant and Animal Cells
6
MITOCHONDRIA Structure Double membrane Have own DNA
Very numerous in high requirement cells (muscles) Function Powerhouse of the cell (energy) Transfers energy into ATP to be used as energy for life functions Cell Type Eukaryotic Cells Plant and Animal Cells
7
CHLOROPLASTS Structure Function Cell Type Double membrane Contains DNA
Contains green pigment (chlorophyll) Function Responsible for photosynthesis Cell Type Eukaryotic Cells Plant Cells
8
LYSOSOMES Structure Function Cell Type Spherical organelles
Contain enzymes Function Digestion Organic molecules Old organelles Foreign substances Cell Type Eukaryotic Cells Plant and Animal Cells
9
CYTOPLASM/CYTOSOL Structure Function Cell Type
Fluid between cell membrane & organelles Contains water, salts, organic compounds Function Aids in movement Cell Type Prokaryotic and Eukaryotic Cells Plant and Animal Cells
10
CYTOSKELETON Structure Function Cell Type
Network of long protein strands Located in the cytosol No membranes Function Support Help with movement of organelles in the cytosol Cell Type Eukaryotic Cells Plant and Animal Cells
11
CELL MEMBRANE Structure Function Cell Type Lipid bilayer Proteins
Selectively permeable Boundary for cell (protection) Cell Type Prokaryotic and Eukaryotic Cells Plant and Animal Cells
12
CELL WALL Structure Function Cell Type Wall outside membrane
Made of cellulose Has pores Function Protect Support Cell Type Eukaryotic Cells Plant Cells
