    Well I guess you'll lose both the marks
    1) you have defined what binomial nomenclature does without going on to the advantages
    2) assuming the radioactive material was amino acids you should explain how the amino acids passed through the double membrane (facilitated diffusion) not random. Therefore they came there for a reason. They are asking you what is that reason. Its a reason .

    go through the papers and reports ... then at the end just read the notes once or twice...also if u can skim through the text book (detailed one) that wud be even better coz it contains some extra info which ll help u!
    Good luck

    Read the specification first. After every point go through your notes about that point. Then do the past papers with timing and thereafter correct your answers yourself using the marking scheme. Read the examiners report after marking. Learn all what you don't know,ask for help here if needed. Meanwhile write down any exam technique you think you must remember and read them through just before the exam.

    Well organisms fall under three domains (the largest group of organisms) . Archae, true bacteria and eukaryotes. Archae and true bacteria was previously classed as prokaryotes. There are many differences between a prokaryotic cell and an eukaryotic cell. Prokaryotes are smaller, have no organised nucleus, no membrane bound organelles, no mitachondria, no chloroplast, no cellulose cell wall(bacteria has a peptidoglycan cell wall), no centrioles or microtubules.....
    and yes plant and animal cells are both eukaryotic. But they have loads of differences. Plant cells have cell walls,vacoules,chloroplast,amylo plasts, piths, and between the plant cells there are middle lamella, plasmodesmata.

    A famous question is "Name two structures in a cell that shows it to be both a plant cell and an eukaryotic one". It can be cellulose cell wall or chloroplast.

    All these we must know.

    Thanks, but when you say chloroplast do you mean that it's also present in the eukaryotic cell?

    How does protein modification take place in prokaryotes, since they don't have a golgi apparatus or rER?
    I doubt we have to know this, but still...
