VST Flashcards
classification
the arrangement of organisms into orderly groups based on their similarities and presumed evolutionary relationships
unicellular
organisms that are made up of only one cell
multicellular
organisms that have many cells
species
a group of living organisms consisting of similar individuals capable of reproducing
heterotroph
an organism that does not make its own food, consumers and decomposers
autotroph
an organism that does make its own food, producers
prokaryote
an organisms whose cells dont have a nucleus
taxonomy
the science of identifying, classifying, and naming living things
dichotomous key
a set of steps that help identify unknown organisms
eukaryote
an organisms whose cells do have a nucleus
scientific name
the name that an organism is called by all scientists. it is based off the organisms genus and species. also called binomial nomenclature
domain
the first division of the modern method of classification, this level contains the most diverse organisms
tissue
A group of cells that work together to perform a specific job in the body
organ
A group of Ɵssues working together to perform a specific job
organ system
Organs working together to perform a parƟcular job
organism
Any thing that can live on its own, are made up of at least one cell
bacteria
Organisms with a prokaryoƟc cell.
diffusion
the movement of particles from a high concentration area to a low concentration area
osmosis
the diffusion of water through the membrane
passive transport
the movement of particles through membrane bound proteins, no energy required.
active transport
the movement of particles through membrane bound proteins against the normal direction of diffusion, energy is required.
endocytosis
the cell membrane surrounds a particle and encloses it in a vesicle, bringing it into the cell.
exocytosis
the fusion of a vesicle to the cell membrane and the release of its contents out of the cell.
photosynthesis
the process where light energy is converted into sugar.
cellular respiration
the process where sugar is converted into cellular energy, ATP.
stomata
small pores in the lower epidermis of the leaf or stem of a plant, forming an opening that allows movement of gases.
transpiration
the use of oxygen to change food into cellular energy.
chlorophyll
A green pigment that is responsible for the absorption of light to provide energy for photosynthesis
reactant
a substance that takes part in and undergoes change during a reaction, the materials that go into a reaction.
product
what is produced by a reaction, that material that comes from a reaction
fermentation
the process where sugar is broken down without the use of oxygen.
