Osmosis and Diffusion: Egg Lab

In this membrane permeability learning exercise, students read introductory information about the cell membrane structure as it pertains to permeabillity and draw a representation of the membrane as they complete a lab. Students record...

Biology buffs illustrate the workings of the cell membrane when they complete this checklist. Not only do they draw the structure, they also draw gradients and mechanisms for the transport of materials across the membrane. Your advanced...

Challenge your biology class to analyze an experimental setup, in which a selectively permeable membrane separates two distinct solutions. They consider the concentration of the contents and answer ten questions pertaining to the...

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Your students will love this PowerPoint! Great visuals will support understanding of membrane proteins, cell membranes, active transport, and diffusion. There are a lot of details on each page and all are relevant. The presentation could...

Without the cell membrane, our cells just couldn't keep it together! What else does this multifunctional membrane do? Take a deeper look at the fluid mosaic model using a video from an expansive biology playlist. Topics include embedded...

Cell membranes and the factors that affect its integrity are studied, with Beet tissue used as the model. A poster to display findings of the permeability of the membranes would clarify understanding and also allow a layer of language...

Explore the structure of cell membranes including cholesterol, glycolipids, glycoproteins, phospholipids, and proteins. The video shows and discusses the fluid mosaic model as well as how cell walls differ from cell membranes. 

Materials don't need a password to move through cell membranes! Learners explore how cells move materials across the cell membrane. The video then teaches the detailed workings of both passive transport (specifically diffusion,...

Cell membranes contain many contradictions; for example, they are both oily and strong. The video explains the parts of a cell membrane, the function of each part, and discusses the contradictions. It highlights what happens when...
