C1.3 Photosynthesis: grass skirts
20 quick questions on photosynthesis, 13 of them at standard level, each answered in a word or two. Print a sheet for each team, a key for the checker and a tick sheet, then tape the sheets to the board and race.
How it runs
- SnipA runner cuts one strip off the bottom of their team’s sheet.
- Answer as a pairBack at the table, they write the answer on the strip. No books.
- Get it checkedThe checker reads it against the key: you, or a student holding it.
- Back for the nextA tick earns the next strip. Wrong? Back to the table to try again.
The questions on this sheet
The checker’s key, with every answer, prints with the sheets.- Green pigment absorbing red and blue light
- Method separating leaf pigments
- Varied by moving a lamp nearer the plant
- Gas converted to sugars in leaves
- Source of the oxygen released by plants
- By-product bubbling from lit pondweed
- Colour leaves reflect rather than absorb
- Spot distance ÷ solvent front distance
- Graph of wavelengths a pigment captures
- Photosynthesis rate at each wavelength
- Input in shortest supply, setting the rate
- Orange pigment running furthest on paper
- Pigment array around a reaction centre
- Light-driven splitting of water
- Hydrogen carrier loaded at photosystem I
- Enzyme fixing CO₂ in the Calvin cycle
- Five-carbon acceptor of CO₂
- Stroma pathway fixing CO₂ into sugar
- Crops grown outdoors at raised CO₂
- Three-carbon sugar the Calvin cycle makes
