24
Q

Chromosomal DNA

A

The DNA of bacterial cells is found loose in the cytoplasm. It is called chromosomal DNA and is not contained within a nucleus.

25
Q

Plasmid DNA

A

Bacteria also have small, closed-circles of DNA called plasmids present in their cytoplasm. Unlike the chromosomal DNA, plasmid DNA can move from one bacterium to another giving variation.

26
Q

Flagella

A

Bacteria can have one or more flagella (singular: flagellum). These can rotate or move in a whip-like motion to move the bacterium.

27
Q

How do bacteria cells multiply

A

Their cells do not divide by mitosis. Instead they copy themselves by binary fission.

28
Q

What size are Eukaryotic cells (plants and animals)

A

Most are 5 μm – 100 μm

29
Q

What size are prokaryotic cells (bacterial cells)

A

Most are 0.2 μm – 2.0 μm

30
Q

What are the features of the outer cell in Eukaryotic cells (plants and animal cells)

A

Cell membrane. Surrounded by cell wall in plants and fungi

31
Q

What are the features of the outer cell in prokaryotic cells (bacterial cells)

A

Cell membrane. Surrounded by cell wall

32
Q

What are the features of the iner cell in eukaryotic cells (plants and animal cells)

A

Cytoplasm. Cell organelles include mitochondria, chloroplasts in plants and ribosomes.

33
Q

What are the features of the inner cell in prokaryotic cells (bacterial cells)

A

Cytoplasm. Ribosomes present. There are no mitochondria or chloroplasts.

34
Q

What genetic material is in Eukaryotic cells( plants and animal cells)

A

DNA in a nucleus. Plasmids are found in a few simple eukaryotic organisms.

35
Q

What genetic material is in Eukaryotic cells( plants and animal cells)

A

DNA in a nucleus. Plasmids are found in a few simple eukaryotic organisms.

36
Q

What genetic material is in Prokaryotic cells( bacterial cells)

A

DNA is a single molecule, found free in the cytoplasm. Additional DNA is found on one or more rings called plasmids.

37
Q

What are light microscopes used for

A

light microscopes are used to study living cells and for regular use when relatively low magnification and resolution is enough

38
Q

What are electron microscopes used for

A

electron microscopes provide higher magnifications and higher resolution images but cannot be used to view living cells

39
Q

How do you calculate magnification level

A

the eyepiece lens X the objective lens.

40
Q

How do you calculate magnification

A

Magnification = size of image / real size of object

41
Q

What can be used to make cells more visible

A

Iodine

42
Q

What is resolution

A

to see two points as two points, rather than merged into one

43
Q

How many millimetres in 1cm

A

10

44
Q

How many micro meters in one cm

A

1000

45
Q

How many nano meters in one cm

A

10000000

46
Q

What are enzymes made of

A

Enzymes are made of proteins

47
Q

What do enzymes function as

A

They are biological catalysts

48
Q

Can enzymes be used up

A

No they cannot get used up

49
Q

What Is the active site

A

The active site is the site where the substrate breaks down the molecule

50
Q

Why do enzymes Denature

A

They denature because they are exposed to extreme PH’s or high temperatures

51
Q

What happens when an enzyme denatures

A

If this happens then the substrate will no longer fit into the enzymes.

52
Q

What is diffusion

A

Diffusion is the movement of particles in a net movement from high to low concentration

53
Q

What factors can affect diffusion

A

Concentrateion gradient, temperature, surface area

54
Q

How does the concentration gradient affect diffusion

A

The greater the difference in concentration, the quicker the rate of diffusion

55
Q

How does the temperature affect diffusion

A

The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly

56
Q

How does surface area affect diffusion

A

The greater the surface area, the faster the rate of diffusion

57
Q

What is osmosis

A

Osmosis is the diffusion of water molecules, from a region where they are in higher concentration, to a region where they are in lower concentration, through a partially permeable membrane.

58
Q

How do you calculate the change in mass

A

(Mass at end - mass at start)/(mass at start ) = x. X x 100

59
Q

What is active transport

A

Active transport is a process that is required to move molecules against a concentration gradient. The process requires energy.
