Membranes, Osmosis & Diffusion

Today we discussed the details of the cell membrane. What is it made out of? As well as how do things move from one side to the other.

Concentration gradients help drive the movement of substances in and out of a cell, which in turn relates to osmosis and diffusion. Here's the animation on osmosis and diffusion that we watched in class.

Homework: Study for your test tomorrow.

Course Description

This course is designed for students to develop an inquiry point of view toward living systems in the context of a changing environment. Laboratory experiments heighten and integrate events at the molecular, cellular and population levels of organization. Independent reading and projects are continually emphasized through out the year.
