MRGRAM Movement Reproduction Growth Response Adaptation Metabolism
species
A group of similar organisms that can breed and produce fertile offspring.
Kingdom
First and Largest category to classify organisms
Viruses
tiny particles, smaller than bacteria and other pathogens, which must invade living cells in order to reproduce; when they invade, the cells are damaged or destroyed in the process releasing new particles to infect other cells
Nutrients
Compounds in food that the body requires for proper growth, maintenance, and functioning
Protein
A three dimensional polymer made of monomers of amino acids. (Meats, fish)
Carbohydrates
Broken down to glucose to provide energy.(Rice, chips)
Lipids
fats and oil
Ingestion
Intake of food
Digestion
Breaking down food
Egestion
excreting of undigested waste
autotrophic nutrition
when an organism produces its own food & is the source of energy for all other living things
Photosynthesis
Conversion of light energy from the sun into chemical energy.
Heterotrophic nutrition
Organisms must consume nutrients from other organisms
Transport
The movement of substances such as oxygen, nutrients, hormones, waste and heat around the body
cellular respiration
Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
aerobic respiration
Respiration that requires oxygen
Anaerobic Respiration
Respiration that does not require oxygen
ATP
(adenosine triphosphate) main energy source that cells use for most of their work
Synthesis
To make, synthesize, needed substances.
