Photosynthesis
What is photosynthesis?
The process by which plants make their own food.
What is the main purpose of cellular respiration?
To produce energy (ATP)
What is an autotroph?
An organism that can produce its own food.
Are photosynthesis and cellular respiration opposite processes or the same process? How?
Opposite because if you flip the photosynthesis equation, you get the cellular respiration equation and vice versa.
What pigment is responsible for capturing light energy in plants?
Chloropyll
What organelle is responsible for photosynthesis?
Chloroplast
Where does cellular respiration occur in the cell?
Mitochondria
What is a heterotroph?
An organism that cannot make its own food and must consume others.
How do the products of photosynthesis relate to the reactants of cellular respiration?
The products of photosynthesis are the reactants of cellular respiration
What do we breathe in that our cells need to produce energy?
Oxygen
What are the reactants of photosynthesis?
Light Energy, Carbon Dioxide, and Water
What are the reactants needed for cellular respiration?
Glucose and Oxygen
Give an example of an autotroph.
Any type of plant
Why is photosynthesis important for cellular respiration?
Because it provides glucose and oxygen needed for cellular respiration.
Why can’t plants survive without animals?
Because plants need carbon dioxide produced by animals for photosynthesis.
What are the products of photosynthesis?
Oxygen and Glucose
What are the products of cellular respiration?
Carbon Dioxide, Water, Energy (ATP)
Can heterotrophs survive without autotrophs? Why or why not?
No, because they rely on autotrophs for food and oxygen.
What energy form do plants use during photosynthesis, and what do cells produce during cellular respiration?
Plants use light energy for photosynthesis, and cells produce ATP during cellular respiration.
Explain how breathing is different from cellular respiration.
Breathing brings oxygen into your lungs and removes carbon dioxide, while cellular respiration uses oxygen inside cells to produce energy.
Write the chemical equation for photosynthesis.
6CO2+6H2O+light→C6H12O6+6O2
Write the chemical equation for cellular respiration on the board.
C6H12O6+6O2 → 6CO2+6H2O+ATP
How do autotrophs and heterotrophs depend on each other?
Autotrophs need heterotrophs to produce carbon dioxide for photosynthesis, and heterotrophs need autotrophs for energy.
Explain why neither process is more important than the other.
Because both processes depend on each other.
