What does the Light Compound telescope do?
It beams light to from an object and the object can magnify up to 1000 times
1 of 40
Resolution of the Light Compound telescope?
It can distinguish two objects from each other
2 of 40
What does the electromagnetic telescope do?
It beams electrons to form an image and can magnify up to 10 000 times
3 of 40
Resolution of the electromagnetic telescope?
Much better than the light compound
4 of 40
What does an animal cell have?
Nucleus, Mitochondria, Cell membrane, Ribosomes, Cytoplasm
5 of 40
What does the Nucleus do?
Controls all activities of the cells ands contains the gene of chromosome that carry instructions to make protein
6 of 40
What does Mitochondria do?
Site of aerobic respiration releasing energy for cell
7 of 40
What does Ribosomes do?
Site of protein synthesis
8 of 40
What does Cytoplasm do?
A liquid gel where chemical cell reactions take place
9 of 40
What does the cell membrane do?
Controls the movement of substances into and out of the cell.
10 of 40
What do plant cells have?
Everything an animal cell has + Vacuole, Chloroplast, Cell wall
11 of 40
What does a Vacuole do?
Filled with cell sap, helps keep cell rigid
12 of 40
What does a Cell wall do?
Strengths the cell and gives it support
13 of 40
What does chloroplast do?
Contains chlorophyll to photosynthesis
14 of 40
What do red blood cells do?
Delivers oxygen to the body tissues via the blood flow. Is flexible and bell shaped. Has no nucleus so bigger surface area to carry oxygen.
15 of 40
What do the white blood cells do?
Protects the body from both infectious diseases and foreign invaders, they ingest pathogens and produce antibodies to destroy pathogens
16 of 40
Two type of white blood cells?
Phagocyte = engulf and digest bacteria, Lymphoncyte = make antibodies that kill pathogens
17 of 40
What do sperm cells do?
Swim to the egg to fertilise it, the tail helps it to swim and the mitrochondria gives it energy to swim to the cell
18 of 40
What to egg cells do?
a large cell with lots of cytoplasm and joins the sperm to fertilise
19 of 40
What do muscle cells do?
They bring about movement and contain protein to help move
20 of 40
What do plant cell do?
Absorbe light by the leaf by photosynthesis, they are vertically elongated.
21 of 40
What does phloem do?
transports sap and sugar to the plant
22 of 40
What do root hair cells do?
They absorb water transport from the roots to the soil.

How does Bacteria reproduce
Binary fusion whereBacteria can get infected by virus which will replicate
24 of 40
How does bacteria make us feel ill?
When in our bodies they release poision and toxins which make us feel ill
25 of 40
Examples of bacteria diseases
Food poising, whopping cough, gonorrhoea
26 of 40
How to treat a bacteria diseases?
They can be treated with antibiotics
27 of 40
How to prevent bacteria diseases
Living in sanitary conditions, preparing food carefully and protected sex
28 of 40
How do viruses reproduce?
The reproduce in host cells, once inside the make hundreds of thousands of themselves till the cell fills and bursts open
29 of 40
How to viruses make us feel ill?
Because they burst open our cells so the virus spreads in the blood stream, airways and other routes and infect neighbouring cells
30 of 40
Examples of virsus
Flu, colds, chicken pox, aids
31 of 40
Treatment for virus?
Non
32 of 40
Prevention
You can be vaccinated against some diseases, protected sex and use sterilise needles
33 of 40
What is in Prokaryotic cells?
Slime capsule, Plasmids, cytoplasm, flagella, cell membrane, genetic material
34 of 40
What are plasmids?
extra rings of DNA
35 of 40
What is flagella?
A long strand used for movements
36 of 40
What are slime capsuls
They are a protective layer
37 of 40
What are Eukaryotic cells?
They are animal, human, plant and fungi cells
38 of 40
Describe the steps that the white blood cell does.
When a disease is present, more white blood cells are produced, so that more of them can ingest the pathogens and more of them can release antibodies. This counteracts with the toxins released by pathogens
39 of 40
What happens with a Vaccine?
a vaccine is introduced to the body containing dead/weak pathogens. This simmulates white blood cells to produce antibodies. White blood cell that produce these remain in the blood and memory cells, so more anitbodies produced if got pathogen again
