Transcript of Cell Structure & Function

Animal Cell
Cell Structure & Function
Network of internal membrane extending through cytoplasm
Endoplasmic Reticulum
Nucleus
Selectively permeable outer covering of cell.
Cell Membrane
What's the difference?
Plant Cell
Double-membrane structure
Chloroplast
Membranous sac
Vacuole
Rigid structure that surrounds plant cells
Cell Wall
Cell Theory
All living organisms are composed of one or more cells.
The cell is the basic unit of life.
All cells arise from pre-existing cells.
Helps maintain cell shape.
Regulates movement into and out of the cell.
Large spherical organelle surrounded by a double membrane.
Control center of the cell.
Contains DNA
Nucleolus
Located within the nuleus
Consists of RNA and protein
Site of ribosomal RNA synthesis
TWO types synthesize lipids and manufacture proteins
Smooth ER
Location of lipid synthesis
LACK ribosomes
Rough ER
Manufactures proteins
Ribosomes located on outer surface
Ribosomes
Granules composed of RNA and protein
Attached to ER and free floating
Synthesize polypeptides
Ribosomes
Cytoplasm
The thick jelly-like substance within the cell membrane.
The cell organelles reside within the cytoplasm.
Lysosome
ONLY IN ANIMAL CELLS!
Membranous sacs
Contain enzymes that break down minerals and secrete wastes
Mitochondria
Powerhouse of the cell
Double membrane organelle
Cite of most cellular respiration
ATP production
Golgi Complex
Stacks of flattened membrane sacs
Site of protien sorting and packaging
Centrioles
Hollow cylinders located near the nucleus
Form spindles used in cell division
Cell membrane is located
inside
the cell wall
Provides structure and support
Store materials such as food and water
Help maintian hydrostatic pressure
Contain chlorophyll
Main site of photosynthesis
When science teachers have guitars.....
