Term
concentration
Definition
mass of solute in a given volume of a solution
Term
diffusion
Definition
particles tend to move from an area where they are move concentrated to an area less concentrated
Term
hypo-tonic
Definition
below strength
Term
hyper-tonic
Definition
above strength
Term
isotonic
Definition
solutions at the same strength
Term
osmosis
Definition
is the diffusion of water through a selectively permeable membrane
Term
equilibrium
Definition
when the concentration of a solute is the same throughout a solution
Term
pinocytosis
Definition
tiny pockets form along the cell membrane ,fill with liquid and pinch off to form vacuoles
Term
phagocytosis
Definition
"cell eating" extensions of cytoplasm surround a particle and package it within a food vacuole
Term
endocytosis
Definition
taking material into the cell by means of infolding
Term
active transport
Definition
cells sometimes move materials in opposite directions
Term
facilitated diffusion
Definition
movement of specific molecules across cell membranes through protein channels
Term
exocytosis
Definition
the membrane of the vacuole surrounding the material fuses with the cell
Term
cell specialization
Definition
cells throughout an organism can develop in different ways to preform different tasks
Term
tissue
Definition
a group of similar cells that preform a particular function
Term
organ
Definition
many groups of tissues that work together
Term
organ system
Definition
a group of organs that work together to preform a specific function
Term
autotroph
Definition
organisms that obtains energy from the sun /make their own food
Term
hetertroph
Definition
organisms that obtain energy from other organisms
Term
ATP
Definition
( adenosine triphosphate) consists of adenosine a 5-carbon sugar called ribose
Term
photosynthesis
Definition
plants use the energy of sunlight to convert water and carbon dioxide into high-energycarbohydrates
Term
pigment
Definition
plants gather the suns energy with light absorbing molecules
Term
NADP*
Definition
a compound carrier molecule
Term
stroma
Definition
the region outside the thylakoid membranes
Term
photosystem
Definition
proteins in the thylakoid membranes organize chlorophyll and other pigments into clusters
Term
thylakoid
Definition
chloroplast contain sac-like photosynthetic membranes
Term
chlorophyll
Definition
the plant principal pigment
Term
light-dependent reactions
Definition
plants that require light
Term
ATP synthase
Definition
a protein contained in the plant membrane
Term
Calvin cycle
Definition
plants use the energy that ATP and NADPH contain to build high-energy compounds
