Energy for Life - Plants Flashcards
Word equation for photosynthesis?
carbon dioxide + water → glucose + oxygen
Symbol equation for photosynthesis?
6CO2 + 6H2O → C6H12O6 + 6O2
Why do plants need nitrates?
Required to make amino acids (and so proteins) and nucleic acids (DNA and RNA)
Why do plants need magnesium?
Required to make chlorophyll
Why do plants need phosphates?
Required to make nucleic acids (RNA and DNA); part of cell membrane
Why do plants need phosphates?
Required to make nucleic acids (RNA and DNA); part of cell membrane
What effects the rate of photosynthesis?
Carbon dioxide levels
Water levels
Light intensity
Temperature
How does CO2 increase rate of photosynthesis?
By adding more carbon dioxide the reaction can happen faster, as there are more molecules to collide with enzymes
How does light intensity increase rate of photosynthesis?
By adding a brighter light we increase the rate photosynthesis, as there is more energy for the reaction to occur.
How does temperature increase rate of photosynthesis?
Increasing temperature speeds up the reaction. This is because the enzymes and substrates have more kinetic energy and collide more often.
What are the products of anaerobic respiration in plants?
glucose –> ethanol + water
