Have chloroplasts
Autotrophs

25
Q

Three characteristics of fungi cells

A

Cell wall– chiton
No chloroplasts
Heterotrophs

26
Q

Semi permeable cell membrane

A

The cell membrane does not allow all things to enter or leave

27
Q

The membrane is made up of two layers of phospholipids so it is known as…

A

Phospholipid bilayer

28
Q

Embedded in the bilayer are _____ that act as channels or pumps to move molecules in or out that can’t fit through the bilayer

A

Proteins

29
Q

These attach to either lipids or proteins in the cell membrane and act in cell to cell recognition, which helps identify foreign cells vs. “self”

A

Carbohydrate chain

30
Q

Cholesterol

A

Can be found among hydrophobic tails and their job is to maintain fluidity and flexibility within the cell membrane

31
Q

Cellular drinking

A

Pinocytosis

32
Q

Sends things out of a cell using energy

A

Exocytosis

33
Q

Example of exocytosis

A

Protein/ enzyme leaving a cell

34
Q

Facilitated diffusion

A

Diffusion of molecules using a protein channel ex: the molecule is big

35
Q

Brings things into a cell using energy

A

Endocytosis

36
Q

Cellular eating

A

Phagocytosis

Ex:amebas eating

37
Q

Hypertonic environment

A

When there is more solute outside of a cell

38
Q

Hypotonic cell

A

More solute inside the cell

39
Q

Isotonic environment

A

There is equal amounts of solute outside and inside of the cell

40
Q

What happens to water in a hypertonic environment

A

It leaves the cell

41
Q

What happens to water in a hypotonic environment

A

It goes into the cell

42
Q

What does water do in a isotonic environment?

A

The water moves equally between the cell and outside environment

43
Q

Osmosis

A

Diffusion of h2o, the water always moves where there is more solute

44
Q

Transport that requires energy

A

Active transport

45
Q

Transfer that requires no energy

A

Passive transport

46
Q

Where do molecules move in passive transport

A

High-> low concentration

47
Q

Where do molecules move to in active transport

A

Low->high concentration

48
Q

3 examples of passive transport

A

Diffusion, osmosis, and facilitated diffusion

49
Q

Two examples of active transport

A

Endocytosis and exocytosis

50
Q

Diffusion

A

Movement of molecules from high to low concentration through the phospholipid bilayer

51
Q

Shapes of eubacteria

A

Coccus, bacillus, spirillum

52
Q

Rod shaped eubacteria

A

Bacillus

53
Q

Spherical shaped eubacteria

A

Coccus

54
Q

Spiral shaped eubacteria

A

Spirillum

55
Q

2 types of prokaryotic cells

A

Eubacteria and archaebacteria

56
Q

Cell wall of archaebacteria

A

Not peptidoglycan

57
Q

Love warm environments

A

Thermophile

58
Q

Love salty environments

A

Halophile

59
Q

Love acidic environments

A

Acidophilus

60
Q

Live in oxygen free environments and produce methane

A

Methanogens

61
Q

Binary fusion

A

The asexual reproduction of pro. Cells where they double the chromosome and split in half
