21
Q

How do you calculate the total magnification?

22
Q

What is another name for the cell membrane?

A

Phospholipid belayer

23
Q

What is a phospholipid made of?

A

Phosphate head and two lipid tails

24
Q

Which part of the phospholipid is water loving or hydrophilic?

A

The phosphate head

25
Q

Which part of the phospholipid is water fearing or hydrophobic?

A

The lipid tails

26
Q

What is a channel protein?

A

It creates a tunnel in the cell membrane to allow larger particles to pass through

27
Q

What is a protein pump?

A

Using energy it moves particles from low concentration to high concentration

28
Q

What function does a carbohydrate serve in the cell membrane?

A

It identifies the cell

29
Q

What is endocytosis?

A

Using energy the cell membrane engulfs large particles and pulls them into the cell

30
Q

What is exocytosis?

A

Using energy the cell membrane expels or releases large particles

31
Q

What is active transport?

A

It requires energy and moves particles from low concentration to high concentration

32
Q

What is passive transport?

A

Transport that does not require energy - moves particles from high to low concentration

33
Q

What is diffusion?

A

Movement of particles from high to low concentrations

34
Q

What is facilitated diffusion?

A

Movement of particles from high to low concentration through a channel protein - passive

35
Q

What is osmosis?

A

The diffusion of water

36
Q

What is a selectively permeable membrane?

A

It allows only some particles into the cell

37
Q

What is an impermeable membrane?

A

It does not allow any particles through

38
Q

What is a hypertonic solution?

A

One where the amount of solute is higher outside of the cell. This means there is more water inside of the cell than outside

39
Q

What happens to a cell in a hypertonic solution?

A

Water leaves the cell and the cell shrinks

40
Q

What is a hypotonic solution?

A

One where the amount of solute is lower outside of the cell. This means there is more water outside of the cell than inside

41
Q

What happens to a cell in a hypotonic solution?

A

What enters the cell and the cell swells

42
Q

What is an isotonic solution?

A

One where the amount of solute is the same inside and outside the cell. This means the water is the same too.

43
Q

What happens in an isotonic solution?

A

Water moves in equal amounts in and out of the cell. The cell stays the same size.
