Do Now:
Explain which type of cell evolved first, the eukaryote or prokaryote!!!
Hmwk: Complete the
worksheet on organelles handout pg4
Do now: Answer the following:
1. Who named the cell a “cell”?
2. What are the 2 types of cells used to category life?
3. What is one difference between the two?
7–1 Life Is CellularA. The Cell Theory
1. Cells are the units of structure and function of all organisms
2. All cells come from pre-existing cells
B. Scientists
1. Robert Hooke
C. 2 Types Cells
1. Prokaryotes: Archaea Bacteria and Eubacteria
2. Eukaryotes1. Ex: WBC, skin cell, cheek cell, plant cell, stem cell

Go to Section:
Cell Membrane
Transport: Movement Through the MembraneA. Cell Membrane is composed of?
protein channel
Carbohydrate chains Lipids
1. Function: Regulates what enters and leaves the
cell: semi-permeable membrane Provides protection and support Cell identification
Go to Section:
B. Transportation
1. Diffusion Movement of molecules from an area of high concentration to
area of low concentration Movement occurs without any ATP Eventually looking for equilibrium, or stability2. Passive Transport Movement of molecules across a membrane going along its
concentration gradient Concentration gradient:
the amount of molecules in a certain area where there is movement from a highly concentrated area to a low concentrated area
07_11Diffusion_A.html
3. Osmosis Diffusion of water through a semi-permeable membrane from
area of high concentration to low concentration Water will move across the membrane until equilibrium has
been reached4. Questions: Movement of Water
1. If high concentration of water molecules in the cell where will the water go?2. If there is a low concentration of water molecules, where will the molecules go?3. When equilibrium is reached is the concentration of the solution in the cell compared to outside of the cell different or the same?

5. What is a solution?Solvent:solute:
C. Types of Solutions
Isotonic: The amount of solutes compared to the amount in a cell are equal to
the amount outside the cell
Hypertonic: The amount of solutes in the solution are high
Hypotonic: Amount of solutes in a solution are low
Study and organize your BINDER!!!! Do Now: List and define the 3 types of solutions

Answer the following:
1. What is the preferred solution for a red blood cell?
2. What will happen to a red blood cell if you place it in distilled water?
3. What will happen to an animal cell if it were placed in a salt water solution?
4. What is the preferred solution for a plant cell?
5. Why can a red blood cell not live in the same type of solution as a plant?
D. More Types of TransportA. Facilitated DiffusionIf a molecule is too large to pass through the membrane, it needs assistance via protein channel.
B. Active Transport Transport of material through the membrane with the use of ATP The molecules are going against the concentration gradient
