Why Are Cells Small?
30 µm 10 µm
Surface areaof one large cube= 5,400 µm2
Total surface areaof 27 small cubes= 16,200 µm2
Cell Types: Prokaryotic
Animal Cell
Plant Cells
MembranesBilipid membrane
Hydrophobic
Hydrophilic
Fluid-mosaic model
Selectively permeable
Plasma Membrane
Nucleus of Cells
The compartment that encloses the DNA DNA is found along
fibers of chromosomes
When cells are not dividing, chromosomes are unraveled
Nucleus of Cells
How genes work
DNA RNA protein
Protein is the gene product (function)
The Endomembrane System
The system is a collection of membranous organelles
These organelles manufacture and distribute cell products
The endomembrane system divides the cell into compartments
Overview of System
Endoplasmic Reticulum
Rough ER Ribosomes Protein synthesis
within vacuoles Plasma membrane
repair
Smooth ER No ribosomes Lipid synthesis Detoxification
Rough ER Secretory Proteins
The Golgi Apparatus
Lysosomes & Vacuoles
Lysosomes & Vacuoles
Cytoskeleton
Skeleton of cells: shape, size, movement, attachment
Cilia and Flagella
