Plasma membrane + tonics

Explain Semipermeable Membrane

allows some substances to pass through while blocking others. The cell membrane lets in small molecules such as oxygen and water but it blocks/regulates larger molecules such as glucose and proteins

Explain Fluid-mosaic model

phospholipids can move within the layer, making it flexible. mosaic describes that it is made up of different components: phospholipids, proteins, cholesterol and carbohydrates

What is phospholipid bilayer?

hydrophilic heads on outside, hydrophobic tails on the inside 

What are proteins

Integral and are involved in transport

Define isotonic

equal solute concentration to another fluid

Define Hypotonic

 a solution with a lower solute concentration compared with another solution

Define Hypertonic

a solution with higher concentration compared with another solution
