Unknown
This is the most common pigment in plants?
Chlorophyll
What color of light is WORST for photosynthesis?
Green/Yellow-green
What colors of light are BEST for photosynthesis?
Red and Blue
Carbon fixation is also called the ____ cycle.
Calvin
What is oxidation?
Loss of electrons
Photosynthesis requires gas exchange. What are the openings in leaves for plants to breathe?
Stomata
How efficient is photosynthesis?
Not very efficient-less than 10%
What is the enzyme that adds CO2 in the Calvin Cycle?
Rubisco
Where is ATP made within the chloroplast? Where specifically is light absorbed by plants?
Inner membrane of the chloroplast- Thylakoid membrane
The energy stored in photosynthesis comes from:
Sunlight
A chemical reaction that releases stored chemical energy is said to be:
Exergonic
Is photosynthesis exergonic or endergonic?
Tell Mr.Hoss why
Endergonic
What are the products of the Light-Dependent reactions of photosynthesis?
NADPH and ATP
The planet's earliest photosynthesis was done by prokaryotes. Where in the cell do photoautotrophs absorb sunlight?
On their Cell Membrane
What is the overall energy storage molecule produced by photosynthesis?
Glucose
What does chlorophyll actually do?
Absorbs light and gets electrons excited
Where do the light-dependent reactions (Calvin Cycle) take place?
In the stroma
Why don't chloroplasts JUST make ATP?
ATP is a giant molecule that only stores a little bit of energy. It's recycled
What is the technical name for the process of using a H+ ion gradient to produce ATP?
Chemiosmosis
Using word parts, what does photo-synthesis mean?
Self Nutrition/ Self Food/ Self Eating
Define Carbon Fixation
Taking carbon (CO2) and sticking into a bigger (Bio)molecule.
Write down the balanced equation for photosynthesis?
6CO2+6H2O+light-> C6H12O6+6O2
A plant is sealed in a jar with light and water. What will happen to its mass?
Mass will increase
Why are plants green?... (what do they do with green light?
Plants aren't good at absorbing/using green light; they absorb other colors, and green is reflected.
Identify three limiting factors for photosynthesis.
Temperature, CO2, Light color, Light intensity, water
