The Importance Of Photosynthesis

Question 0

Define the term autotroph

Answer 0

• Organisms that use light energy or chemical energy and inorganic molecules (co2 and h2o) to synthesise complex organic molecules

Question 1

Define the term heterotroph

Answer 1

• organisms that ingest and digest complex organic molecules, releasing the chemical potential energy stored in them

Question 2

Explain the importance of photosynthesis

Answer 2

• 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

Question 3

Where does photosynthesis take place?

Answer 3

• takes place in chloroplasts
• it is a two stage process
- 6co2+6h20 (+ light energy) —-> c6h12o6 + 602
