28
Give examples of what can be a pathogen (4)
1) Bacteria 2) Fungi 3) Protoctists 4) Virus
29
Virus
Non living particle. It is only active inside cells of other living organisms
30
What do animal and plant cell have in common? (4)
1) Nucleus 2) Cell membrane 3) Cytoplasm 4) Mitochondrion
31
What do animal and plant cell have different?
1) Vacuole (plant) 2) Chloroplast (plant) 3) Cell wall (plant)
32
Which layer is cell membrane?
Inner layer
33
Nucleus (2)
1) Contains DNA | 2) Controls the cell
34
Cell membrane
Controls the entry and exit to and from the cell
35
Mitochondrion
Releases energy
36
Cytoplasm
Site of cell reactions
37
Vacuole (2)
Stores water and maintains shape
38
Cell wall
Provides protection and support
39
Chloroplast (2)
1) Contains chlorophyll | 2) Site of photosynthesis
40
Give a kingdom and an example for: | A unicellular with a nucleus cell with temporary vacuoles
Protoctist - Amoeba
41
Give a kingdom for: | An extremely small, with no actual structures, protein coat and DNA
Virus
42
Give a kingdom and an example for: | Chitin cell walls, cell membrane, nucleus
Fungi - Yeast
43
Give a kingdom for: | Plasmid DNA, cell wall, cell membrane, circular chromosome
Bacteria
44
Adaptations of a red blood cell (3)
1) Large surface area - biconcave disk 2) Thin membrane 3) No nucleus
45
Why Large surface area is an important adaptation for red blood cells?
To absorb and release as much oxygen as possible
46
Why Thin membrane is an important adaptation for red blood cells?
Flexible, to squeeze through narrow capillaries
47
Why no nucleus is an important adaptation for red blood cells?
No nucleus, so more haemoglobin can fit
48
Adaptations of sperm cell (3)
1) Tail 2) Release dissolving enzymes from the tip of the head 3) Contain many mitochondria
49
Haploid
Contain half of the DNA
50
Why Tail is an important adaptation for a sperm cell?
Moves itself to the egg
51
Why releasing enzymes is an important adaptation for a sperm cell?
Digest the pathway into the egg cell
52
Why many mitochondria is an important adaptation for a sperm cell?
Releases as much energy as possible to move quicker
53
Adaptation of cilia?
Continually flicker and move
54
Why movement of cilia is an important adaptation for a ciliated cell?
They can move mucus, dirt out of the lungs
55
Why ciliated cells located in the trachea?
Keep it clear
56
Why ciliated cells located in the oviducts?
Move the egg
57
Adaptations of Mesophyll cells? (2)
1) Contain lots of chloroplast | 2) Positioned in the upper part of the leaf
58
Why chloroplast is an important adaptation for a mesophyll cell?
Can produce own food by photosynthesis
59
Why positioning in the upper part of the leaf is an important adaptation for a mesophyll cell?
Can absorb maximum sunlight
