The Importance Of Photosynthesis Flashcards
0
Q
Define the term autotroph
A
• Organisms that use light energy or chemical energy and inorganic molecules (co2 and h2o) to synthesise complex organic molecules
1
Q
Define the term heterotroph
A
• organisms that ingest and digest complex organic molecules, releasing the chemical potential energy stored in them
2
Q
Explain the importance of photosynthesis
A
- without photosynthesis, complex molecules aren’t made and heterotroph’s can’t gain energy
- nearly all life depends on it
- releases 02 and h20 into atmosphere and respiration depends on oxygen and glucose
3
Q
Where does photosynthesis take place?
A
• takes place in chloroplasts
• it is a two stage process
- 6co2+6h20 (+ light energy) —-> c6h12o6 + 602
