photosynthesis Flashcards
what take of reaction is photosynthesis
an endothermic reaction (takes in energy)
how does photosynthesis work
light energy is taken in from the sun it is trapped by chloroplasts which carry out photosynthesis and make food (chemical energy)
whats the equation for photosynthesis
6CO2 + 6h2O = 6o2 + C6H12O6
what can glucose be used for in respiration
to make energy by respiration
to make proteins for growth
stored in the leaves as starch
what does chlorophyll absorb
it absorbs light energy, products, sugar and starch
where does cell respiration take place
in the mitochordria
what are photosynthesis limiting factors
light intensity
temperature
carbon dioxide concentration
if a limiting factor is in short supply what happens
then photosynthesis cannot go at its maximum rate
