ecosystems Flashcards
aerobic respiration
Breaking down glucose with oxygen to release energy and producing carbon dioxide and water.
algae
Green uni-cellular or multi-cellular organisms that perform photosynthesis and live underwater.
anaerobic respiration
Releasing energy from the breakdown of glucose without oxygen, producing lactic acid (in animals) and ethanol and carbon dioxide (in plants andmicroorganisms).
biotechnology
The use of biological processes or organisms to create useful products.
chlorophyll
Green pigment in plants and algae which absorbs light energy.
deficiency
A lack of minerals that causes poor growth.
fermentation
A type of anaerobic respiration in which glucose is converted into ethanol, carbon dioxide, and energy.
fertiliser
Chemicals containing minerals that plants need to build new tissues.
haemoglobin
The substance in blood that carries oxygen around the body.
iodine
Indicator used to test for the presence of starch.
magnesium
A mineral needed by pants for making chlorophyll. It is an element in group 2 of the Periodic Table.
nitrates (biology)
Minerals containing nitrogen for healthy growth.
oxygen debt
Extra oxygen required after anaerobic respiration to break down lactic acid.
phosphates
Mineral containing phosphorus for healthy roots.
photosynthesis
The process plants and algae use to make their own food, glucose. In photosynthesis, carbon dioxide and water react together to make glucose and oxygen.
