The Living Environment

HideShow resource information
Physiological Function
any substance that is involved in chemical reactions in a living organism has a physiological function
1 of 33
Specific Heat Capacity
the measure of the amount of heat energy needed to heat up a particular mass of a material through a particular temperature rise. Water has a high specific heat capacity so it heats up and cools down slowly
2 of 33
Thermophilic
heat-loving, such as the bacteria that live around hot volcanic vents and springs
3 of 33
Ambient gases
the surrounding environmental gases that are available to all organisms
4 of 33
Atmosphere
the gases surrounding the Earth
5 of 33
Photolysis
the splitting of molecules by light, including the splitting of water molecules in the early atmosphere, producing oxygen.
6 of 33
Greenhouse gas
a gas that absorbs infrared radiation and causes atmospheric heating
7 of 33
Transpiration
the loss of water by evaporation from the stomata of leaves
8 of 33
Biosphere
all the living organisms on Earth
9 of 33
Hydrosphere
all the water on the Earth, found in solid, liquid or gaseous form
10 of 33
Lithosphere
the relatively hard outer layer of the Earth, consisting of the crust and upper layer of the mantle
11 of 33
Biomimetics
the study of living organisms so the knowledge gained can be applied to engineering or technological developments
12 of 33
Teratology
the study of the causes of birth defects
13 of 33
Indigenous species
species that are native to the area
14 of 33
Gene pool
the total variety of different genes in all the members of a population
15 of 33
Vavilov centre
an area of the world where crop plants were first domesticated and where wild varieties are still found
16 of 33
CITES
the Convention on International Trade in Endangered Species
17 of 33
Niche
the niche of a species is the role it plays in its habitat, which includes how it makes use of resources and responds to the other species in its habitat
18 of 33
Endemic
an endemic species is indigenous to a particular area and is not naturally found elsewhere
19 of 33
Wildlife and Countryside Act
a UK Act of Parliament that provides protection for many wildlife species and designated protected areas
20 of 33
SSSIs
Sites of Special Scientific Interest
21 of 33
NNRs
National Nature Reserves
22 of 33
SPAs
Special Protection Areas
23 of 33
SACs
Special Areas of Conservation
24 of 33
MNRs
Marine Nature Reserves
25 of 33
Ramsar Sites
A wetland site designated to protect its biodiversity
26 of 33
International Whaling Commission
the IWC is an international organisation that aims to ensure the sustainable exploitation of whales
27 of 33
EU common fisheries policy
the EU agreement to manage fishing and aquaculture. It attempts to balance the needs of the Member States and their fishing industries with sustainable exploitation of the environment
28 of 33
Inbreeding
describes breeding between closely related individuals. Inbreeding increases the risk of recessive genes producing offspring with disadvantageous characteristics
29 of 33
Cryopreservation
the preservation of material by freezing, such as the freezing of semen for artificial insemination
30 of 33
Artificial Insemination
a form of selective breeding where semen is collected from a chosen male and is inserted artificially into the chosen female to cause her to become pregnant
31 of 33
Embryo Transfer
the transfer of fertilised eggs or embryos from a female of a rare species, into females of closely related more common species. This enables more young to be produced.
32 of 33
Micro-propagation
a tissue culture method where large numbers of plants can be produced from a tissue sample from an original plant, without the need for seeds
