Photosynthesis Flashcards
Structure in a cell where photosynthesis happens.
Chloroplast
Chemical present in chloroplasts which traps light energy
Chlorophyll
Energy change during photosynthesis
Light energy to Chemical energy
Raw materials for photosynthesis
Carbon dioxide and water
End products of photosynthesis
Glucose and oxygen
What other factors are needed for photosynthesis to happen?
Light and chlorophyll
A series of enzyme-controlled reactions, in a two-stage process called…
Photosynthesis
The first stage of photosynthesis
Light reaction
The second stage of photosynthesis
Carbon fixation stage
The light energy from the sun is trapped by chlorophyll in the chloroplasts and is converted into chemical energy in the form of ….
ATP
In the light reaction, water is split to produce…
Hydrogen and oxygen.
Which products of the light reaction are used in the carbon fixation stage?
ATP and Hydrogen
Name the gas released during photosynthesis.
Oxygen
Name the three substances needed during the Carbon fixation stage.
ATP, Hydrogen and Carbon dioxide
List the 3 ways that glucose, produced during photosynthesis can be used.
Storage, Respiration and Structural
Look at the graph below.
What is the limiting factor between A and B?
What is the limiting factor between B and C?
Temperature
What is the limiting factor between A and B?
Light intensity
What is the limiting factor between B and C?
Temperature or CO2 concentration
Look at this graph.
What is the limiting factor at point A1, between A1 and A2 and between A2 and A3?
What is the limiting factor at a CO2 concentration above A2, when the light intesity is medium?
A1, A1-A2 & A2-A3 - CO2 concentration
Above A2 - Light intensity
