Photosynthesis
what is the purpose of photosynthesis
to convert sunlight into chemical energy
What is the main purpose of cellular respiration
to break down food and release energy
What type of organisms carry out photosynthesis
plants, algae and some bacteria
What waste product is released during cellular respiration
Carbon dioxide
What is the primary energy source for photosynthesis
sunlight
What organelle is responsible for photosynthesis
where does cellular respiration take place
mitochondria
What is ATP
The energy molecules use
Which of the following statements is true?
a) Only animals perform cellular respiration
b) Plants do not use cellular respiration
c) Plants perform both photosynthesis and cellular respiration
d) Animals perform both photosynthesis and respiration
c) Plants perform both photosynthesis and cellular respiration
what happens to excess glucose in plants
it is stored for later use
What is the main pigment used in photosynthesis
chlorophyll
what gas is required for cellular respiration
oxygen
How are photosynthesis and cellular respiration related
the products of one are the reactants of the other
What happens to glucose during cellular respiration
It is broken down to release energy
why is cellular respiration necessary for life
it breaks down food to release usable energy
What are the reactants of photosynthesis
carbon dioxide and water
what are the products of cellular respiration
carbon dioxide, water, and ATP
Which factor does NOT affect photosynthesis?
a) Light intensity
b) Carbon dioxide levels
c) Temperature
d) The presence of ATP
D) The presence of ATP
What is a producer
an organism that makes its own food
what role do mitochondria play in cellular respiration
they convert glucose into energy
What are the products of photosynthesis
oxygen and glucose
What is the equation for photosynthesis?
a) C6H12O6 + 6O2 → 6CO2 + 6H2O + ATP
b) 6CO2 + 6H2O + Light Energy → C6H12O6 + 6O2
c) H2O + ATP → CO2 + O2
d) O2 + C6H12O6 → Sunlight + H2O
b) 6CO2 + 6H2O + Light Energy → C6H12O6 + 6O2
What molecule stores the energy produced during cellular respiration
ATP
What process is responsible for releasing oxygen into the atmosphere
photosynthesis
What would happen if photosynthesis stopped
energy flow in food webs would collapse (we die)
