Chapter 3: Cell Structure and Function

Cell Structure

Interactive diagrams of plant and animal cell structures

http://www.cellsalive.com/cells/cell_model.htm

(Main Idea: Cells have an internal structure.)

Cell Signaling

Article, illustrations, and an animation explaining how cell membrane proteins are involved in cell signaling

http://learn.genetics.utah.edu/content/begin/cells/insidestory/

(Main Idea: Chemical signals are transmitted across the cell membrane.)

Diffusion and Osmosis

Engaging British video explaining diffusion and osmosis and their roles in life processes

(Main Idea: Diffusion and osmosis are types of passive transport.)

Endocytosis

Video of a living single-celled organism using endocytosis to engulf a particle of food

http://www.dnatube.com/video/7271/Amoeba-Phagocytosis

(Main Idea: Endocytosis and exocytosis transport materials across the membrane in vesicles.)

Exocytosis

Article about cell transport including videos of vesicles moving within live cells and fusing with the cell membrane.

http://learn.genetics.utah.edu/content/begin/cells/vesicles/

(Main Idea: Endocytosis and exocytosis transport materials across the membrane in vesicles.)

Summary of Transport

Simulation in which you move various substances across a cell membrane to visualize different types of transport

(Main Ideas: Some molecules diffuse through transport proteins. Proteins can transport materials against a concentration gradient. Endocytosis and exocytosis transport materials across the membrane in vesicles.)
