Cell Membrane What is it? – Barrier that separates cell from external environment – Composed of two phospholipid layers Other molecules are embedded in.
Passive vs. Active Transport. Passive Transport Does NOT require energy Moves substances from higher to lower concentration.
Moving Cellular Material Chapter 2, Lesson 3. Membranes Control the movement of materials in and out of cell. – Semipermeable – only certain substances.

Passive Transport Concentration Gradient: the difference in the number of molecules in one area than in another area Requires no energy Goes from an area.

Cells and the Cell Cycle Chapters 7 & 10

History What Hooke saw…

The Cell Theory The cell theory states: All living things are composed of cells. Cells are the basic units of structure and function in living things. New cells are produced from existing cells.

Prokaryotes

Eukaryote Cells Generic Animal Cell Plant Cell

Cell Membrane

Transport Through the Membrane Diffusion

Osmosis The movement of water

Facilitated Diffusion

Active Transport Endocytosis Exocytosis Protein Pumps Pinocytosis & Phagocytosis

Cell Specialization Function follows form…

Levels of Organization

Ideal Cell Size…

Cell Cycle G1… Cell grows and synthesizes new proteins S… Cell replicates it’s DNA G2… Cell makes organelles required for replication

Mitosis… cellular replication…

Animal organelles & mitotsis

Plant Cell Cytokinesis

Regulating Cell Growth Contact

Proteins regulate growth too… Cyclins Internal External

Unregulated Growth… Cancer
