Cell Theory
1. All living things are made of cells. 2. Cells are the basic units of structure and function in an Organism. 3. New cells are produced from existing cells.
Robert Hooke
Looked at a cork with a microscope and saw little structures he called "cells."
Anton van Leeuwenhoek
Looked at water with a microscope and saw tiny living organisms (microorganisms)

Organism
Homeostasis
process by which organisms maintain a relatively stable internal environment
Prokaryote
NO NUCLEUS, No membrane-bound organelles, Most cells are simple. Evolved 3.5 billion years ago.
Eukaryote
HAS Nucleus, MANY Organelles, Cells are complex. Evolved 1.5 billion years ago.
Things Cells have in Common
Cell Membrane, Cytoplasm, Genetic Material, Ribosomes
Things Plant Cells Have that Animal Cells Don't
Cell Wall, Vacuole, Chloroplast.
Cell Membrane
regulates what enters and leaves the cell
Cell Wall
strong layer around the cell membrane in plants, algae, and some bacteria
Lipid Bilayer
Double-layered sheet that forms the core of nearly all cell membranes.
Protein Channel
Helps move material across the membrane.
Marker Protein
identifies the cell
Receptor Protein
Recieves chemical signals
Passive Transport
1. No Energy is needed 2. Moves with the gradient. 3. Moves from high to low.
Diffusion
When molecules move from high to low.
Osmosis
A type of diffusion in which water goes from high to low.
Facilitated Diffusion
When a protein channel helps a molecule move across the membrane.
Equilibrium
Both sides of the membrane are equal
Hypertonic
Moving Out of the Cell
Hypotonic
Moving In the Cell
Isotonic
Moving In and Out of the Cell
Active Transport
1. Requires Energy 2. Move from low to high 3. Moves against the gradiant.
Endocytosis
Cells bring in particles using the cell membrane.
Phagocytosis
Ingestion of large particles using energy.
Pinocytosis
Tiny pockets form along the cell membrane, and pinch off into vacuoles inside the cell.
Exocytosis
Particles move out.
Vinegar; Out/Hypertonic, Syrup: Out/Hypertonic, Water: In/Hypotonic
Vinegar moved ________, Syrup moved ________, Water moved __________.
Permeable
allowing (especially liquids) to pass or diffuse through
Semi-Permeable
membranes that allow some substances through but not others
Color Change
What indicates a positive test.
Smaller Cell
This size can diffuse faster then the other sizes.
