The yellow and the blue together make the phopholipid bilayer. (Blue hydrophobic, and yellow hydrophilic). The pink is the protein which helps in the transport.

A Cell Membrane

The Cell MembraneAntonia Simas

Above are pictures of different types of solutions, Hypertonic, Hypotonic and Isotonic. A hypertonic solution is when there is more water on the outside than the inside, so some of the water will leave the cell causing it to become shriveled. A hypotonic Solution happens when there is less water on the inside of the cell, causing the cell to swell up. An isotonic solution is when there is equal amount of water in both the cell and outside, so there is no net change, meaning nothing will change.

Introduction to the Cell Membrane, what is a cell membrane, parts of the cell membrane, and types of transport. The cell membrane is what separates the inside of the cell with the environment outside. For a cell to take in nutrients and get rid of all its wastes, it must be transported through the cell membrane by active or passive transport

Plamolysis is when the cytoplasm detaches from the cell when it shrinks due to loss of water

There are two types of transport, active (uses atp) and passive (no atp).

The types of passive transport are facilitaded
