QUESTION
Tap the card to reveal the answer
QWhat is the overall equation of photosynthesis?
A6CO₂ + 6H₂O + light → C₆H₁₂O₆ + 6O₂
QWhere in the cell does photosynthesis happen?
AIn chloroplasts
QWhat pigment captures light energy?
AChlorophyll (mainly in the thylakoid membranes)
QWhat are the two stages of photosynthesis?
ALight-dependent reactions and the Calvin cycle (light-independent)
QWhat do the light reactions produce?
AATP and NADPH (and O₂ from splitting water)
QWhat does the Calvin cycle do?
AUses ATP and NADPH to fix CO₂ into sugar
QWhy are plants green?
AChlorophyll reflects green light while absorbing red and blue
QWhere does the oxygen released come from?
AFrom splitting water molecules — not from CO₂
QWhat are stomata?
ALeaf pores that let CO₂ in and O₂/water vapor out
QWhat factors limit the rate of photosynthesis?
ALight intensity, CO₂ concentration, and temperature

- One fact per card. Own the overall equation first — every detail card hangs off knowing what goes in and what comes out.
- Rate honestly. After each card, choose Again, Hard, Good, or Easy — the spaced repetition algorithm uses your answer to decide when the card returns, right before you'd forget it.
- A few minutes daily beats marathons. Ten new cards a day is roughly 3,650 a year, retained. Deep dives: How to make flashcards that actually work · The spacing effect, explained · How to study for exams with flashcards.
