Answers are for parents and teachers.
1
Write what the outer covering of animal, plant and fungal cells is made of.
Animal: membrane only (with glycocalyx); plant: cellulose wall; fungus: chitin-like wall.
2
How many cells of 20 µm diameter fit along 2 mm? (2 mm = 2000 µm)
100
3
How do substances pass between rough ER and the Golgi complex?
Through vesicles.
4
Why can white blood cells perform phagocytosis but plant cells cannot?
White blood cells have a thin, flexible membrane; a plant cell is surrounded by a thick cellulose wall.
5
Sort the cell’s organelles into membrane and non-membrane types.
Non-membrane: ribosome, cell centre. Membrane: ER, Golgi, mitochondria, plastid, lysosome, vacuole.
