Photosynthesis Flashcards
What organisms can do photosynthesis?
Some protists, some bacteria, and plants
What pigment captures light?
Chlorophyll
What light does chlorophyll absorb?
Red and blue.
What light does chlorophyll reflect?
Green light
Where is chlorophyll found?
Chloroplasts
What two processes happen in photosynthesis?
Light dependent and light independent reactions.
What are some other names for the light independent reactions?
Calvin Cycle; the dark reactions
Where do light dependent reactions happen?
Thylakoids
Where are thylakoids found?
Chloroplasts
What is a collection of thylakoids called?
Granum
What are multiple granum called?
Grana
What do the light dependent reactions use?
Light. Water is used but it is split.
What is water split into in light dependent reactions?
Electrons, protons, oxygen
What do light dependent reactions produce?
Oxygen, ATP, NADPH
What do the lighthouse independent reactions (Calvin cycle) need?
NADPH, ATP
Where do the light independent reactions happen?
Stroma
What is the stroma?
The fluid outside of the thylakoids
What do the independent reactions use?
CO2, ATP for energy, NADPH for adding high energy electrons
Where are gasses exchanged from in plants?
Stoma
What is the plural of stoma?
Stomata
What can open and close the stoma?
Guard cells
What happens when CO2 enters the pant?
It is changed into a usable ORGANIC form by an enzyme.
What do the light independent reactions make?
Glucose
