17. What is a eukaryotic cell?
Eukaryotic cells have a distinct nucleus and possess membrane-bound organelles.
They are different from prokaryotic cells, such as bacteria (we will look at these next lesson).
With an electron microscope, details of organelles within these cells can be seen.

29. Peer Assessment
M1.(a) (i) (Aerobic) respiration; Accept ATP production / energy release Reject anaerobic respiration Reject energy production 1 (ii) Golgi (apparatus / body); Ignore smooth ER

30. Peer Assessment
(b) (‘It’ = Optical microscope) Ignore reference to magnification 1. Has low resolution / not high enough resolution; Accept converse relating to EM 2. (Because) wavelength of light not short enough / too long; Accept larger wavelength Accept statements that microscopes have a wavelength

31. Peer Assessment
M2.(a) 1. How to break open cells and remove debris; 2. Solution is cold / isotonic / buffered; 3. Second pellet is chloroplast; 3 (b) 1. A stroma; 2. B granum; Accept thylakoid 2

32. Peer Assessment
(c) 1 (d) Two of the following for one mark; Mitochondrion / ribosome / endoplasmic reticulum / lysosome / cell-surface membrane 1 max [7]

33. How did they do?
11 – 8 = Brilliant! Now read ahead on specialised cells. 7 – 5 Fair. Do a quick recap organelles, use of electron microscopes and calculating magnification. 4 – 0 Oh dear. Deep revision needed! Recap organelles, use of electron microscopes and calculating magnification.
