Photosynthesis Flashcards
The oldest known fossils
Stromatolites
Serial endosymbiosis suggests
Mitochondria developed before plastids
The process that converts solar energy into chemical energy within chloroplasts
Photosynthesis
Sustain themselves without eating anything derived from other organisms
Autotrophs
The interior tissue of the leaf is called the
mesophyll
Where are chloroplasts found?
Usually the mesophyll
Microscopic pores in the leaves that allow for exchange of O2 and CO2.
Stomata
The membranes of the chloroplasts are the
stroma
Connected sacs in the chloroplast that compose a third membrane system
Thylakoids
Stacks of thylakoids are called
Grana
The pigment that gives leaves their green color
Chlorophyll
Resides in the thylakoid membrane
This is the equation for
Photosynthesis
What is the relationship between photosynthesis and cellular respiration?
Photosynthesis is the reverse of cellular respiration
Photosynthesis is a ____ process
redox
In photosynthesis, ____ is oxidized.
H2O
In photosynthesis, ____ is reduced
CO2
Is photosynthesis an exergonic or endergonic reaction?
Endergonic
The energy is supplied by light
What are the two types of reactions in photosynthesis?
Light and “dark”
Which set of reactions in photosynthesis:
- Split H2O
- Release O2
- Reduce the electron acceptor NADP+ to NADPH
- Generate ATP from ADP by photophosphorylation
Light reactions
In which set of reactions in photosynthesis does
The Calvin cycle (in the stroma) forms sugar from CO2, using ATP and NADPH
Dark reaction
The distance between crests of electromagnetic waves.
Wavelength
What wavelengths produce visible light?
380 nm to 750 nm
What colors does Chlorophyll a absorb?
- Red
- Violet
- Blue
What colors does Chlorophyll b absorb?
- Orange
- Blue
