    Is the squash slide similar to a wet mount? When preparing a slide for light microscopy..

    Well for squash slide you have to prepare a wet mount and then you use a lens tissue to press down the cover slip on the sample. Its best used for soft samples such as for root tip squashes.

    Literally the whole spec.. I think we might have a 6 marker on one of:
    Transpiration
    Transcription and translation
    DNA replication
    Cardiac cycle

    On the breadth there wasn't much on
    Diffusion
    Active transport
    Meiosis and mitosis (other than 1 multiple choice question)
    Plant defence mechanisms (callose and chemicals)
    Thank you

    By the way, does anyone have any tips on time management? Should I do the 6 markers first and then the rest of the paper or what?
    I always do them as they come up and just go through the paper like a book, then go back to any I miss out

    Lol transcription won't come up - there was a 4 marker on it in the specimen papers.
    Lol DNA replication won't come up, there was also a 4/5 marker on it in specimen papers.
    I'm feeling mitosis and meiosis

    Anything else? I feel that microscopes would come up.

    Well the specimen papers don't matter as they are not actual papers.. Look at Q6 on depth specimen paper, we had a similar one on breadth,
    In all seriousness even translocation (came up in breadth) has a chance of popping up

    Apparently laser scanning confocal microscopy is new in this spec (wasn't on previous spec) so id say that has a higher chance of coming

    Oh yeah where was transcription on the specimen paper Ronny?

    That's the most confusing one.. It's the one with dyes right? Can't remember how it worked.

    What do I need to know about plant defences?
    Plants have active and passive defences. Passive defences are already present before infection and will prevent the entry of any pathogen.
    Passive defences include physical barriers such as cellulose cell wall, waxy cuticle, lignin, stomatal closure, tylose and callose. Chemicals include terpernoids, phenols, alkaloids & hydrolytic enzymes. These are only produced when a pathogen is detected as they require a lot of energy.

    Active defences just fortify passive defences e.g. extra cellulose and callose. Active defences also include necrosis which is deliberate cell suicide of a part of the plant that is infected and canker which is death of cambium tissue in the bark.

    I think we only need to be able to recognize which pictures are from which microscopes for that part of the spec

    How do the pictures look like for the laser scanning thing look like?

    Experiment-type questions i found quite difficult, dont really know if tomorrow will be better than the specimen
