Q

What are the components of a bacterial cell?

A

chromosomal dna (no nucleus)
plasmids
cell membrane
ribosomes
flagellum

17
Q

function of plasmids

A

contain genes for the bacteria such as antibiotic resistance

18
Q

function of flagellum

A

allows bacteria to move or ‘swim’

19
Q

What is a specialised cell?

A

a cell that has certain adaptations to help it carry out its function

20
Q

examples of specialised cell

A

egg cell , sperm cell , ciliated epithelial cell

21
Q

adaptations of egg cell

A
  • large cytoplasm makes space for developing embryo
  • membrane closes after fertilisation to avoid polyspermy
  • haploid nucleus (half the number of chromosomes in a normal cell)
  • egg cell also carries female dna
22
Q

how many chromosomes are there in a haploid nucleus

A

23 chromosomes, in other body cells there are 46

23
Q

adaptations of sperm cell

A

-flagellum allows it to swim towards the egg cell
- mitochondria supplies it with energy
- acrosomes allow it to dig into the egg’s cell membrane
- haploid nucleus
- streamlined shape allows it to swim to the egg faster

24
Q

adaptations of ciliated epithelial cell

A
  • line the surfaces of organs
  • some of them have little hairs called cilia
  • move substances in one direction along the surface of a tissue
