What are bacteria?

A

Microscopic single celled lrganisims

20
Q

What do bacteria contain?

A

Cell wall, cell membrane, cytoplasm and plasmids, no nucleus but contain a circular chromosome of DNA

21
Q

Do bacteria carry out photosynthesis?

A

Some do but mose fee off other living or dead organisms

22
Q

What is a pathogen?

A

Any disease causing fungi, bacteria, protoctists or virus’s

23
Q

Are viruses living?

A

No, they are small particles, smaller than bacteria, they are parasitic and can only reproduce inside living cells, they can infect evry type of living organism

24
Q

What is a viruses cellular structure?

A

No cellular structure, but have a protein coat, and a nucleic acid that is either DNA or RNA

25
Q

What is an example or a virus?

A

HIV which caused AIDs

26
Q

What structures are in both animal and plant cells?

A

Nucleus, ribosome, cell membrane, mitochondria, cytoplasm,

27
Q

What does the nucleus do?

A

Comtrols the activities of the cell, and contains the dna

28
Q

What is the cytoplasm?

A

Jellylike, and the site of chemical reactions

29
Q

What do ribosomes do?

A

Make proteins

30
Q

What do mitochondria do?

A

Site of aerobic respiration

31
Q

What does the cell membrane do?

A

Controls what goes in and out of the cell

32
Q

What does the cell wall do?

A

Holds shape

33
Q

What does the choloplasts do?

A

Absorbs light for photosynthesis

34
Q

What is the function of the vacuole?

A

Where cell sap is stored and keeps the cell firm

35
Q

What is diffusion?

A

Diffusion is the net movement of particles from an area of hight concentration to and area of low concentration down a concentration gradient until dynamic equilibrium is reached

36
Q

What is active transport?

A

The movement of particles from an area of low concentration to an area of hugh concentration using energy ( Adenosine triphosphate)

37
Q

What is osmosis?

A

Osmosis is the movement of water molecules from am area of high water potential, through an area of low water potential, through a partially permeable membrane. It is a passive process

38
Q

What factors affect the rate of diffusion?

A
  • shorter distance to diffuse
  • steep concentration gradient
  • increasing temperature
  • smaller particles
39
Q

What happens to the surface area to volume ration as the cube increase?

A

Decreases
