what type of cell is a plant cell
prokaryotic
1 of 33
what part of a cell makes proteins
ribosomes
2 of 33
what extra parts do plant cells have
chloroplasts, permanant vacuole, rigid cell wall
3 of 33
what is the function of the cell membrane
conrols what goes in and out, supports
4 of 33
what part of the cell controls chemical reactions and how
cytoplasm, enzymes
5 of 33
what are the parts of a bacteria cell
cell wall, membrane, circular strands of dna, plasmid, cytoplasm
6 of 33
what are the parts of a light miscroscope
light, stage, lenses, stage, fine and coarse adjustment knobs
7 of 33
what is the definition of differentiation
the proces a cell undergoes to become specialised
8 of 33
type of specialised cells and how they are adapted for their function
sperm, mitochondria=energy for swimming, enzymes in head=digets through egg cell membrane, streamline= swim faster
9 of 33
how is a root hair cell adapted for its function
big surface area for absorbing water and mineral ions
10 of 33
deffinition of stem cell
undifferentiated cell that can turn into any type of cell
11 of 33
where can you find adult stem cells
bone marrow
12 of 33
what can embryonic stem cells be used for
create insulin producing cells for those with diabetes
13 of 33
what can adult stem cells be used for
replace red blood cells for those whove lost some or have damged red blood cells
14 of 33
what are the advantages of embryonic stem cells
theraputic cloning can be done to replicate patients dna so cell wont be rejected
15 of 33
what is an argument against using embryonic stem cells
the emebryo is a possible life
16 of 33
whta rae the two parts of the cell cycle
1. growth and dna replication 2. mitosis
17 of 33
what is mitosis
when a cell divides
18 of 33
how is mitosis carried out
1. chromosomes line up in centre andthey are pulled apart (diomand shaped) 2. membrane forms around 2 sets of chromosomes, becomes nucleas of cell, its divided 3. sytoplasm and membrane idvide
19 of 33
how do prokaryotic cells divide
binary fission
20 of 33
what is the definition of diffusion
spreading out of particles from an area of high concentration to low concentration
21 of 33
what increases the rate of diffusion
higher temperature,concentration, larger surface area
22 of 33
where in the body does diffusion occur
cell membrane, small particles such as oxygen, glucose and amino acids
23 of 33
what is osmosis
movement of particles across a partially permeable membrane from an area of high to low water concentration
24 of 33
what is active transport
when somethng moves from an area of low concentration to high
25 of 33
where in humans is active transport used
the gut, when theres a lower conc of nutrients in gut than blood, allows glucose to be taken into blood to be transported
26 of 33
how is active transport used in plants
root hair cells, take up minerals from soil where there is generally a lower conc of minerals
27 of 33
what does active transport require to work
energy and respiration
28 of 33
what makes something adapted to exhange substances
thin membrane, large surface area, lots of blood vessels, ventialted
29 of 33
what affects how easy it is for an organism to exchange substances
surface area to volume ratio
30 of 33
how are villi adapted for substance exchange
single layer of surface cells, good blood supply, big surface area
31 of 33
how leaves are adapted for substance exchange
air spaces in cell, flat leaf shape increase surface area,guard dells conrol stomata
32 of 33
how are fish adapted for substance exchange
gill filaments covered in lamelle, lamelle hav ethin membrane and lots of blood capillaries, high cncentration gradient mantained
