photosynthesis Flashcards
what are heterotrophs
organisms that ingest and digest complex organic molecules releasing their chemical potential energy
what are chemoautotrophs
organisms that synthesise complex organic molecules using energy from exergonic reactions
what are photoautotrophs
organisms that use light energy to synthesise complex organic molecules from inorganic ones
what are autotrophs
organisms that use light energy or chemical energy to synthesize complex organic molecules from inorganic molecules
how many photosystems are there in photosynthesis
2
which photosystem comes first
2
what are the two stages of photosynthesis
light dependent and light independent
where does photosynthesis occour
the thylakoid
what is the role of the photosystems
to absorb light and transfer it to electrons and energy
what are photosynthetic pigments
molecules that absorb light energy and are arranged in photosystems
