Terms in this set (24)
Describes a living thing that is composed of a group of similar cells living together, each cell being capable of living individually.
A group of similar cells that work together to perform a specific function.
A group of tissues that work together to perform a specific function.
A group of organs that work together to perform a life function.
An organism that manufactures its own food (energy source), such as plants and algae.
An organism that obtains food by eating other organisms.
The breakdown of a food source such as a sugar to release usable energy for a cell.
ATP (adenosine triphosphate)
The molecule that serves as a usable form of energy for the cell; like coins instead of gold bars.
aerobic cellular respiration
The process by which cells use oxygen to obtain usable energy from an energy source (sugar); uses mitochondria.
anaerobic cellular respiration
The process by which cells obtain usable energy from an energy source (sugar) without using oxygen; all reactions occur in the cytoplasm; produces small amounts of ATP; also called fermentation.
ATP, carbon dioxide, water
What are the products of aerobic cellular respiration?
lactic acid fermentation
An anaerobic process used to break down carbohydrates/sugars to produce ATP, carbon dioxide, and lactic acid; performed by bacteria, muscle cells, etc.
An anaerobic process used to break down carbohydrates/sugars to produce ATP, carbon dioxide, and ethyl alcohol; performed by yeast and some bacteria.
A fuel derived directly from living matter; ethanol is a type in which sugar from crops like wheat and corn go through alcoholic fermentation. The ethanol is collected and refined/purified.
alcohol or lactic acid, carbon dioxide, ATP
What are the products of anaerobic cellular respiration/fermentation?
consumers and producers
Which organisms perform some type of cellular respiration to transform stored energy of sugar into ATP?
The assembly process producers use to form simple sugars from carbon dioxide and water, using light energy and chlorophyll inside chloroplasts.
A colored chemical compound that absorbs light energy, producing color.
The green pigment found in the chloroplasts of plant cells that captures the light energy necessary for photosynthesis.
Which organisms perform photosythesis?
sunlight, carbon dioxide, water, chlorophyll
What are the reactants of photosynthesis (items needed to perform photosynthesis)?
sugar and oxygen
What are the products of photosynthesis?
light-dependent and light-independent reactions
What are the two stages of photosynthesis?
An item or process that is so amazingly complex, it had to be fully formed by God and functional from the beginning or it could not exist at all--true of both photosynthesis and cellular respiration.
