Transcript of Cellular Structure and Function

Cellular Structure and Function
Cells
All living creatures are composed of cells
Smallest units that retain the properties of
life
1) Composed of cells
2) Requires energy
3) Steady internal conditions
4) Grow, develop, reproduce
5) Populations evolve



Prokaryotes
Single-celled organisms like bacteria

Lack most cellular structures or organelles
Anatomy of a Bacterium Cell
Prokaryotes: Structures & Molecules
Capsule:
outer layer - protection
Cell wall:
inside capsule

-

protection/shape
Plasma membrane:
layer inside cell wall
Cytoplasm:
fluid area inside cell
Ribosomes:
protein production
Plasmid:
small, circular DNA
Pili:
conjugation
Nucleoid region:
single chromosome
Flagellum:
movement



Eukaryotes
Usually multicellular

Includes
animals
,
plants
, fungi and protists
Anatomy of an Animal Cell
Anatomy of a Plant Cell
Animal Cells: Structures & Molecules
Plasma (cell) membrane:
controls entry/exit of molecules
Cytoplasm:
fluid area inside cell
Nucleus:
contains chromosomes
Nucleolus:
ribosome formation
Golgi apparatus:
protein folding
Centriole:
spindle fiber formation
Lysosome:
digestion
Endoplasmic reticulum:
protein (rough) and lipid (smooth) synthesis
Mitochondria:
ATP production


Plant Cells: Structures & Molecules
Plants contain all of the same organelles as animals plus the following:
Cell wall:
protection and shape
Central vacuole:
stores water, nutrients, wastes, chemicals
Chloroplasts:
photosynthesis
