phospholipid bilayer

# data[].attributes.body
Cell membrane is semi-permeable

# data[].attributes.body
Cell membrane lets things in and out of cells. It also protects the cell.

# data[].attributes.body
phospholipids have a polar head and a fatty acid tail.

fluid mosaic model also has carbohydrates and cholesterol

# data[].attributes.body
Fluid Mosaic Model

# data[].attributes.body
protein and cholesterol embedded into cell membranes

# data[].attributes.body
non polar tail and polar heads on phospholipids

# data[].attributes.body
Cells have a large surface area

# data[].attributes.body
only lets some molecules in and out of the cell

# data[].attributes.body
Carbohydrates serve as receptors to send and receive signals on the cell membrane.

# data[].attributes.body
lets certain molecules in/out of cell

# data[].attributes.body
Separates the inside of the cell from the outside

# data[].attributes.body
In/out of cell

# data[].attributes.body
Its ability to differentiate between different types of molecules, only allowing some molecules through while blocking others.

# data[].attributes.body
Some substance are able to pass through the membrane and others cannot

# data[].attributes.body
Made of phospholipids, carbohydrate indicators and cholesterol to make the phospholipid bilayer. Phospholipids are composed of a polar head and 2 hydrophobic fatty acid tails. It’s also semipermeable

# data[].attributes.body
Salt is alone with water on the other side

# data[].attributes.body
The side where the salt water is will only have salt left at the end

# data[].attributes.body
important to let things out of cell into body (exocytosis) -> when molecules exit the cell membrane

# data[].attributes.body
The separation of salt and water symbolizes cell membrane allowing nutrients in, waste out.

# data[].attributes.body
Proteins serve as transport channels on the cell membrane

# data[].attributes.body
Salt is hydrophilic

# data[].attributes.body
salt would not be able to enter the fresh water side but the water molecules would

represents the selective permeability of the cell membrane

# data[].attributes.body
regulates what comes in and out of the cell

# data[].attributes.body
the powerhouse of the cell

# data[].attributes.body
To allow certain molecules to enter and exit, but not everything. Protects the cell.

Polar heads allow polar stuff to pass through, but not stay in the fatty acid part

# data[].attributes.body
small holes between phospholipids, and proteins allow molecules to pass through

# data[].attributes.body
water will pass between but salt stays on salt side, therefor the solutions don’t really mix
