mitochondrea
where respiration takes place in a cell
1 of 22
ribosome
the site of protein synthesis
2 of 22
chloroplasts
filled with chlorophyll, this is the site of photosynthesis in a plant cell
3 of 22
magnification
the number of times bigger an image is compared to the original side
4 of 22
resolution
the ability to distinguish between 2 points clearly
5 of 22
differentiation
when a cell becomes specialised
6 of 22
adaptation
special features of the cell that allow it to carry out specific functions
7 of 22
prokaryote
single-celled organisms that usually have free genetic material not dound in the nucleus E.G. bacteria
8 of 22
flagella
a whip-like structure that allows bacterial cells to move
9 of 22
chromosomes
thread like structures of DNA found in the nuclei of organisms. humans have 23 pairs of chromosomes in adult cells
10 of 22
karyotype
the visual appearance of an organism's chromosomes
11 of 22
mitosis
part of a cell cycle where chromosomes are ouled apart to form 3 new nuclei
12 of 22
cystokinesis
when a cel divides after mitosis
13 of 22
embryonic stem cells
undifferentiated cells found in emybryos that can make any type of specialised cell
14 of 22
tissue specific stem cells
undifferentiated cells found in parts of the body that can make specialised cells from that area only
15 of 22
osmosis
the diffusion of water from a dilute solution (high concentration of water) to a concentrated solution (low concentration of water) across a partially permeable membrane
16 of 22
isotonic
a solution that is the same concentration as the cell contents so there is no net movement of water
17 of 22
turgid
the swelling of a cell that has taken in water by osmosis
18 of 22
flaccid
the shrinking of a cell that has lost water by osmosis
19 of 22
active transport
the movement of particles against the concentration gradient from a low concentration to a high concentration, it requires ATP from respiration
20 of 22
ATP
the final product of cellular respiration that is used by protein channels during active transport
21 of 22
respiration
the release of energy as a result of the reaction between glucose and oxygen in mitochondria
