Characteristics of life Flashcards
(20 cards)
single celled organisms (ex: bacteria)
unicellular
organic molecules that make the cells genetic material; contains code for what a living thin is and what it does
nucleic acid
the process of becoming larger ( increase in size)
growth
organisms that cannot make their own food and obtain energy by feeding on other organisms ( ex; animals and fungi)
heterotroph
the most abundant chemical in cells; H2O; an inorganic molecule
water
living things
organisms
organic molecules, aka “oils and fats’ used in cells as building matereials and a backup energy source
carbohydrates
a change in an organisms surroundings that causes the organism to react
stimulus
the combination of chemical reactions through which an organism builds or breaks down materials; all of the chemical reactions occurring in the cells of an organism
metabolism
basic unit of structure and function in an organism; building blocks of life
cell
organisms that make their own food (ex; plants)
autotroph
the process of change that occurs during an organisms life, producing a more complex organism
development
reproduction that involves two parents and combines their genetic material to produce a new organism that differs from both their parents
sexual reproduction
maintenance of a constant, stable, internal conditions
homestis
organic chemicals that serve as cell’s main energy source
lipids
organic molecule that is used for many things, including being the main building material for cells
proteins
an action or change in behavior, what an organism does to react to a stimulus
response
reproduction that involves only one parents and produces offspring that are identical to the parent
asexual reproduction
organisms that are composed of many cell (animals and planets)
multicellular
