First two chapters
What is photosynthesis?
the process by which green plants and some other organisms use sunlight to synthesize.
What are Chloroplasts similar to?
mitochondria
What is the letter A in the equation?
It is the variable.
What is the is the primary pigment
Chlorophyll.
What does Chlorophyll do?
Chlorophyll absorbs red and blue light and reflects green light.
Where is former photosynthesis commonly seen?
plants, algae and cyanobacteria.
What does CAM stand for?
Crassulacean acid metabolism
What is CAM found in ?
in plants adapted to very hot and dry environments, such as cacti and pineapples.
What do C4 photosynthesis use?
Plants such as maize and sugarcane .
What do all types of photosynthesis produce?
They all produce sugars from CO2 using the Calvin cycle, but each pathway is slightly different.
What are the types of photosynthetic process
oxygenic and anoxygenic.
What must be transferred to a pigment protein complex that can convert it to chemical energy.
Light energy
What happens when a photon of lights hits the reaction center?
A pigment molecule such as chlorophyll releases an electron.
What happens in the second step of calvin cycle?
The 3-PGA is reduced, meaning it takes electrons from six NADPH molecules and produces two glyceraldehyde 3-phosphate.
What are Pigment molecules associated with ?
Proteins
HOW DO PLANTS ABSORB SUNLIGHT FOR PHOTOSYNTHESIS?
Plants contain special pigments that absorb the light energy needed for photosynthesis.
What is the Calvin Cycle?
The three-step process that generates sugars for the plant
What does the Calvin Cycle use?
The ATP and NADPH are produced in chlorophyll to generate carbohydrates.
What happens when stomata opens?
Water vapor is lost to the external environment, increasing the rate of transpiration and C02 is allowed in.
What are the main types of photosynthesis?
C3, C4 and CAM.
what is the equation to photosynthesis
6CO2 + 12H2O + Light Energy → C6H12O6 + 6O2 + 6H2O
WHERE IN THE PLANT DOES PHOTOSYNTHESIS TAKE PLACE?
Photosynthesis occurs in chloroplasts, a type of plastid
How do plants observe sunlight for photosynthesis?
Plants contain special pigments that absorb the light energy needed for photosynthesis.
What if humans had photosynthetic skin?
our skin would only be green where it was exposed to the Sun.
HOW IS CARBON DIOXIDE AND OXYGEN EXCHANGED?
Plants absorb CO2 from the surrounding air and release water and oxygen via microscopic pores on their leaves called stomata.
