Unit 2, Cell Structure and Function: grass skirts

51 quick questions across the whole of Unit 2 (a fresh 30 on each print), 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

  1. SnipA runner cuts one strip off the bottom of their team’s sheet.
  2. Answer as a pairBack at the table, they write the answer on the strip. No books.
  3. Get it checkedThe checker reads it against the key: you, or a student holding it.
  4. 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.
  1. rRNA and protein, found in all life
  2. Ribosome-studded membrane network
  3. Makes lipids and detoxifies, no ribosomes
  4. Stacked sacs that tag and package proteins
  5. Sac of hydrolytic enzymes in animal cells
  6. Plant cell's large sac of water
  7. Double-membraned organelle of respiration
  8. Organelle where photosynthesis occurs
  9. Holds most of a eukaryote's DNA
  10. DNA region of a prokaryote, no membrane
  11. Folds of the inner mitochondrial membrane
  12. Rigid cellulose layer outside the membrane
  13. Small membrane bubble that moves cargo
  14. Falls as a cell grows, limiting its size
  15. Fingerlike projections on gut lining cells
  16. Soil-facing outgrowth that boosts uptake
  17. Double layer with tails facing inward
  18. Proteins drifting in a sea of lipids
  19. Spans the bilayer, like a channel or pump
  20. Loosely bound to the membrane surface
  21. Steroid that buffers membrane fluidity
  22. Sugar-tagged marker for cell recognition
  23. Lets some substances cross but not others
  24. O₂ crossing the bilayer with no protein
  25. Solute difference that drives diffusion
  26. Uphill movement of a solute, spending ATP
  27. Taking in material by membrane infolding
  28. Cell eating: engulfing large particles
  29. Vesicles fusing to secrete their contents
  30. Passive transport via a channel or carrier
  31. Channel that lets water cross fast
  32. Hydrophilic pore that ions pass through
  33. Diffusion of water across a membrane
  34. Having more solute than the cell
  35. Having less solute than the cell
  36. Same solute level as the cell
  37. Ψ, the sum of pressure and solute terms
  38. Equals −iCRT, zero or negative
  39. Membrane pulling away from the wall
  40. Push of a full vacuole against the wall
  41. Bails water out of a freshwater protist
  42. Keeping body water and solute balance
  43. Moves 3 Na⁺ out and 2 K⁺ in using ATP
  44. Voltage of about −70 mV across a cell
  45. One solute rides another's gradient in
  46. Charge plus concentration difference
  47. Keeping reactions apart behind membranes
  48. ER, Golgi, vesicles and lysosomes as one
  49. Engulfed prokaryotes became organelles
  50. Cell lacking a nucleus, like a bacterium
  51. Cell with a nucleus and organelles
