what is the function of the Plasma Membrane (or cell membrane
- Regulate that enters
2. Semipermeable membrane
what can enter the plasma Membrane
small, hydrophobic molecules
ie. CO2 , O2
small uncharged polar molecules
ie .H2O
What can not enter the cell Membrane
Large Polar Molecules
ie: Amino Acids , Glucose, Nucleotides
What kind of model is the cell Membrane
Fluid Mosaic Model
What does Fluid Mosaic Model mean?
Constantly moving arrangement of proteins
Where is Cytoplasm
Between cell membrane and the nuclear membrane
What does the Cytoplasm contain?
the Organelles
What takes place in the Cytoplams
Reactions
Where are Free Ribosommes
Free floating in cytoplasm
What do Ribosome’s carry?
Proteins
Where are attached Ribosommes
on the Rough Enduplasm reticulm
Nucleus?
Control center of the cell
What does the Nucleolus make?
Ribosommes
Nuclear pore
How substances leave the nucleus
Nuclear Membrane
surrounds the nucleus
Prokaryotic cells are…
Simple cells
Properties of Prokaryotic cells are
small,simple,unicellular,spheres,rods,spirals,DOESN’T HAVE A MEMBRANE BOUND NUCLEUS,flagella (used for movement)
Eukaryotic cells are….
Complex and Larger than prokaryotic.
Properties of Eukaryotic cells?
Large,membrane bound organelles,multicellular (they can be uni but mostly multi, ie. Yeast)
Viruses are….
Nonliving and replicate in cells
what three scientist contributed to the cell theory
Schwann, Schleiden and Virchow
Chromatic
Makes DNA and condenses to chromozones
Mitochondrion
Power house of the cell and makes ATP energy
What does ATP energy stand for?
adenosine Tripohsphate
