pigment

a substance that has a colour

enzyme

a protein that speeds up chemical reactions without being changed itself

anabolic process

a chemical reaction which occurs when small, simple molecules are built up into large, complex molecules

synthesis

cellular respiration

process during which cells break up glucose molecules to release energy that the cells can use

catalyse

make reactions happen faster

optimum

which temperature at which something works best

denature

to change the structure of proteins such as enzymes irreversibly

light phase

the light dependant stage of photosynthesis that occurs in the grana of chloroplast

dark phase

the light independent stage of photosynthesis that occurs in the stroma of chloroplast

ADP (adenosine triphosphate)

the liquid inside chloroplast

variegated

patches of different colours on something such as a leaf

limiting factors

the factors that limit the speed or rate of a process(e.g like photosynthesis)

productiviy

in a plant this refers to to how much extra dry mass it gains over a period of time
