Photosynthesis Flashcards
where does photosynthesis happen?
in the chloroplasts
what does the pigment chlorophyll do in the leaf
absorbs light energy and uses this energy to convert carbon dioxide and water into glucose and oxygen
word equation for photosynthesis
carbon dioxide + water ➔ glucose + oxygen
what is the chemical symbol equation for photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
Which type of reaction is photosynthesis?
endothermic, because it requires energy from the sun
What can the glucose made during photosynthesis be used for?
- Stored as starch for later
- Respiration
What can the glucose made during photosynthesis be used for?
- Stored as starch for later
- Respiration
What is the molecular formula for glucose?
C6H12O6
How do plants get the carbon dioxide required for photosynthesis?
It diffuses from the air into the leaves via stomata
How do plants get the water required for photosynthesis?
It diffuses from the soil into the root hair cells by osmosis
What makes starch a useful long term storage molecule?
- It is insoluble in water
- It is compact
- It can easily be broken down when needed
One use of glucose is to make amino acids.
What else do plants need to make amino acids?
Nitrate ions
