Cells The CELL THEORY:

– All living things are made of cells.– Cells come from pre-existing cells.– Cells are the basic unit of structure and function

in all living organisms.

Page 3: REVIEW!!!!!!!!!! Cells, The Scientific Method and Organic Molecules.

The Plant Cell Cell Wall provides

support and protection.

Cell Membrane is located within cell wall and encloses all organelles and cytoplasm.

Page 4: REVIEW!!!!!!!!!! Cells, The Scientific Method and Organic Molecules.

The Animal Cell The Cell Membrane is

selectively permeable allowing specific nutrients and waste in and out of cell.

Composed of three organic molecules; carbohydrates, proteins and lipids.

Page 5: REVIEW!!!!!!!!!! Cells, The Scientific Method and Organic Molecules.

Cellular Organelles Mitochondria – aids in cellular respiration,

produces energy “ATP”. Ribosomes – aids in protein synthesis. Vacuoles – Storage of wastes (small found

in animal cell, while large is found in Plant cell only!)

Page 6: REVIEW!!!!!!!!!! Cells, The Scientific Method and Organic Molecules.

Cellular Organelles Centrioles – aids in cell reproduction,

found only in Animal Cells. Chloroplasts – aids in photosynthesis,

found in Plant Cells only. Cytoplasm – Fluid substance that all

organelles exist in. Nucleus - contains DNA.

Transport through Cell Membrane

Diffusion – movement of high concentration to low concentration.

Active Transport – movement of low concentration to high concentrations. Moves against the concentration gradient.

Osmosis – diffusion of water.

Page 9: REVIEW!!!!!!!!!! Cells, The Scientific Method and Organic Molecules.

Organic Molecules Contains Carbon and Hydrogen Examples are: Carbohydrates (Sugars,

Glucose), Proteins, Lipids (Fats) and Nucleic Acids (RNA & DNA).

Make up all cell walls and membranes.

The Scientific Method1. State the Problem;

How, Why, What?2. Research/Inferences3. Form a Hypothesis;

create a statement. If….then..

4. Develop a controlled experiment. Only one variable is being tested.

5. Analysis of Data – read and interpret charts, graphs and written findings.

6. Formulate Conclusion- no summary, state if hypothesis is proven or not.

Page 11: REVIEW!!!!!!!!!! Cells, The Scientific Method and Organic Molecules.

Graphs !! Label axes with units. Figure out an appropriate scale; the spacing

between numbers on axes must be in equal increments.

Independent variable; factor that influences the dependent variable, always on the x-axis.

Dependent variable; what you are measuring, always on y-axis.
