Q

What is plasmid DNA

A

Small loop of dna that isn’t chromosomal dna and plasmids contains genes for drug resistance

22
Q

What are eukaryotes

A

Complex and include all animal and plant cell

23
Q

What are prokaryotes

A

Smaller and simpler including bacteria cells

24
Q

why is an electron microscope better than a light microscope

A

larger bacterial cells may be visble using a light microscope but an electron microscope would be needed to see the details of cell organelles

25
Q

what is the flagellum

A

a whip like tail

26
Q

what is bacteria

A

single cell organism prokaryotic cells

27
Q

how to bacteria cells divide

A

using binary fission

28
Q

name three specialised animal cells

A

sperm , egg cell, cilliated epithetial

29
Q

what are eukaryotes made out of

A

eukaryotic cells

30
Q

why are plant cells,animal cell, protists and fungi eukaryotic

A

because it has a cytoplasm, cell memebrane and nucleus

31
Q

what two groups can cells be classified as

A

prokaryotic or eukaryotic

32
Q

where do eukaryotic cells contain their dna

A

enclosed in the nucleus

33
Q

do prokaryotic cells contain their dna enclosed in the nucleus

34
Q

do bacteria cells have a nucleus

35
Q

what are specialised cells

A

cells that have adaptations which help them carry out a particular function

36
Q

what is diffrentiation

A

is a process that involves the cell gaining new subcellular structures in order for it to be suited for its role

37
Q

diffrent cells have what kind of functions

A

diffrent fucntions

38
Q

what do multicellular organisms contain

A

lots of diffrent types of cells

39
Q

what do scientists call it when a cell has become speicalised

A

diffrentiation

40
Q

what is the job of a sperm cell

A

fertillisation/ to join with an ovum

41
Q

what is fertillisation

A

when a sperm cells joins with an ovum

42
Q

what are 4 key things that sperm cells contain

A
  1. a tail which helps them swim faster and because they are streamlined which makes swimming to the ovum easier
  2. enzymes which allows them to digest their way through the outer layer of the ovum
  3. a lot of mitachondria to swim the distance
    4.has genetic information in the nucleus, however sperm cells have half of the genetic information of an adult cell
43
Q

what is the job of a nerve cell

44
Q

is a sperm cell eukaryotic or prokaryotic

A

eukaryotic

45
Q

eukaryotes are…

A

plants,animials, protsits and fungi cells

46
Q

prokarytoes are..

A

bacteria cell

47
Q

what is a prokaryote made up of

A

prokaryotic cells

48
Q

what is aerobic respiration

A

a process that uses glucose and oxygen to release energy

49
Q

name 5 common animal cells

A
  1. skin cells
  2. muscle cells
    3.nerve cells
  3. fat cells
    5.blood cells
50
Q

what is another word for red blood cells

A

erythrocytes

51
Q

what are red blood cells suspended in

A

blood plasma

52
Q

4 adaptations of a root hair cell

A
  1. thin walls for short diffusion distance
  2. many mitochondria to release energy from respiration for active transport in order to absorb mineral ions
  3. roots are long , deep and can spread out to absorb water from a large surface area
  4. many root hair cells for large surface area to absorb more water
