Biology

Osmosis
the movement of water molecules from a region of high concentration to a region of low concentration
1 of 25
diffusion
the spreading out of particles from an area of higher concentration to an area of low concentration.
2 of 25
limiting factor
environmental conditions that limit the growth, or distribution of an organism or population of organisms
3 of 25
respiration
the process of transferring energy from glucose to every cell of an organism
4 of 25
pathogen
microorganisms that enter the body and cause disease.
5 of 25
antibodies
proteins produced in white blood cells that lock on to pathogens and slow down the spread of disease.
6 of 25
vaccination
process of injecting small amounts of dead or inactive pathogens into a person so antibodies will recognise those same pathogens enter the body in the future.
7 of 25
anaerobic respiration
respiration without oxygen, breaking glucose down into lactic acid.
8 of 25
antibiotics
substances that kill or prevent the growth of bacteria without damaging other cells.
9 of 25
photosynthesis
how plants use solar energy to transfer carbon dioxide and water into glucose and oxygen.
10 of 25
chromosomes
threads of genetic information inside the nucleus
11 of 25
gene
small amounts of genetic information passed from a parent to the offspring inside the chromosomes.
12 of 25
variation
differences in appearance within a species, caused by differences in genotype.
13 of 25
biotic factors
living factors
14 of 25
aerobic respiration
respiration with oxygen, glucose + oxygen -> carbon dioxide + water
15 of 25
active transport
the movement of ions or molecules through a cell membrane into an are of higher concentration.
16 of 25
community
an interacting group of various species in a common location.
17 of 25
eukaryote
complex cells like plant and animal cells.
18 of 25
gamete
egg and sperm cells
19 of 25
genome
the entire set of genetic material in an organism
20 of 25
meiosis
asexual reproduction where 4 daughter cells with half the number of chromosomes are produced.
21 of 25
metabolism
the chemical reactions in an organism.
22 of 25
mitochondria
where most of the reactions for aerobic respiration take place.
23 of 25
oxygen debt
the amount of extra oxygen your body needs during exercise.
24 of 25
prokaryote
smaller simpler cells like bacteria.
