B2.2 Organelles and compartmentalization: grass skirts
19 quick questions on organelles and compartmentalization, 10 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.- Discrete subunit of a cell with a function
- Organelle where mRNA is made and edited
- Membrane sac of hydrolytic enzymes
- Stack of cisternae that processes proteins
- Breaking cells and separating organelles
- Machine spinning samples at high speed
- Cell where mRNA meets ribosomes at once
- Sac holding an engulfed bacterium
- Keeping incompatible reactions apart
- Protein fibre network, not an organelle
- Folds of the inner mitochondrial membrane
- Flattened sac holding the photosystems
- Fluid around the grana in a chloroplast
- Opening that lets mRNA out to ribosomes
- Ribosome-studded sacs for export proteins
- Makes proteins kept in the cytoplasm
- Unedited RNA copy still in the nucleus
- Mitochondrial gap where protons build up
- Protein coat that shapes budding vesicles
