function. CB1d Inside Bacteria B1.1 B1.5 Explain how the sub-cellular structures of eukaryotic and prokaryotic cells are related to their functions, including: ... (c) bacteria - chromosomal DNA, plasmid DNA, cell membrane, ribosomes and flagella. Demonstrate an understanding of the relationship between quantitative units, including (a) milli (10-3), micro nano (10-9), pico (10-12) 1) Write the word ‘bacteria’ on the board. Discuss with students the sub-cellular structures that they would expect to find in bacterial cells. 2) Remind students that both plant and animal cells are described as being eukaryotic because they have nuclei. Establish the idea that eukaryotic cells contain nuclei but prokaryotic cells do not. Students examine live yoghurt cultures to look for bacteria. Even at the highest magnifications, bacteria will appear very small. Students should draw outlines of any bacteria they can see. Equipment: Live yoghurt (liquid varieties are more useful), sterile toothpicks/cocktail sticks, access to beaker of 1% Virkon in which to dispose of used toothpicks, light microscope, microscope slide, coverslip, water or methylene blue stain, paper towel, gloves, pipette. Optional: microscope with ×100 oil-immersion objective, video camera and display, non-live yoghurts. Write up A × 10n on the board and explain how standard form works. Use arrows to illustrate how the unit moves by the number of times shown by the power of ten, both to the left and right for positive and negative powers.

Explain that the fungus is Students investigate the action on starch solution of amylase from their own saliva or with prepared amylase solution, using the iodine test. Demonstrate to students how starch can be synthesised from a potato.
