Test review for the Cell Transport Test tomorrow.

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)

1st Level of Organization

Organ System

5th Level of Organization



process by which organisms maintain a relatively stable internal environment


NO NUCLEUS, No membrane-bound organelles, Most cells are simple. Evolved 3.5 billion years ago.


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.


When molecules move from high to low.


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.


Both sides of the membrane are equal


Moving Out of the Cell


Moving In the Cell


Moving In and Out of the Cell

Active Transport

1. Requires Energy 2. Move from low to high 3. Moves against the gradiant.


Cells bring in particles using the cell membrane.


Ingestion of large particles using energy.


Tiny pockets form along the cell membrane, and pinch off into vacuoles inside the cell.


Particles move out.

Vinegar; Out/Hypertonic, Syrup: Out/Hypertonic, Water: In/Hypotonic

Vinegar moved ________, Syrup moved ________, Water moved __________.


allowing (especially liquids) to pass or diffuse through


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.
