    Anyone have any ideas what might/due to come up.
    :confused:

    I´d say respiration as a long question cuz photosynthesis came up last year. n the usual ecology, genetics,reproduction...


  • Closed Accounts Posts: 1,504 ✭✭✭Nehpets


    ugh....biology


  • Registered Users, Registered Users 2 Posts: 25 Oatesy


    Make sure you know the female reproduction hormones. they are the only thing that havent been asked yet in the chapter


  • Registered Users, Registered Users 2 Posts: 1,152 ✭✭✭carlowboy


    I'm banking on that Oatesy!

    Know Protein Synthesis is my recommendation.


  • Registered Users, Registered Users 2 Posts: 25 Oatesy


    Right heres a list of stuff my teacher is saying.

    Iaa (Auxin) experiemnt
    Genetic screening
    Resparation
    That female hormones one i mention.
    Protein synthesis As mentioned above. anything else ?

    Hows about experiments people? Im thinking:

    All effects on catalase activity
    IAA
    Enzyme Immob.
    Light intensity and co2 on photosynthesis

    Any other ideas?


  • Registered Users, Registered Users 2 Posts: 1,152 ✭✭✭carlowboy


    Not Immobolised Enzyme. Other 3 should come up, maybe osmosis too but that's a pass one.


  • Closed Accounts Posts: 57 ✭✭whatshername!!


    thanks. Im thinking enzymes and osmosis and diffusion coz they avent come up yet. Im dreading 2moro goin to be my worst day by far!:(


  • Closed Accounts Posts: 42 Tula


    there's pretty much always plant reproduction or human reproduction right? and ecology or food?


  • Registered Users, Registered Users 2 Posts: 4,195 ✭✭✭Corruptedmorals


    Yes, always genetics, reproduction, plant stuff and ecology..think food comes up every year year too, in some part. Respiration is being tipped more than photosynthesis, woohoo. I still can't grasp photosynthesis, and I've tried so hard..as soon as it mentions protons..:(

    Genetics, Repoduction, Respiration/Photosynthesis (possibly a double question), The Sense Organs, Microbiology, Ecology


  • Closed Accounts Posts: 100 ✭✭alancork


    The sense organs have never come up yet, i.e. the ear, eye etc...know the eye and the ear well anyway!:D

    Oh my God, its going to suck. I still have to do respiration... Please let it be nice. I need a B2 realistically.....C2 in the Pre....can it be done?? lol
    Actually, came across a question in the photosynthesis experiment while ago. I presume its to do with the water bath, but i'm so tired I don't really know?

    Q: why is elodea (a water plant) used instead of a wood plant in this exp.

    Is it just cause you're putting it in a waterbath??

    In the papers they kinda go male/female/male/female with regards repro. I think its male meant to come up this year, then again, gambling never works...


  • Registered Users, Registered Users 2 Posts: 427 ✭✭izzyflusky


    So u can measure the reate of photosynthesis by counting the O2 bubbles

    lol im going for an A1 and I got a c2 so there is hope for you yet! its gonna be a tough paper I think the food experiments will come up!


  • Closed Accounts Posts: 201 ✭✭Spank


    I'm leaving out the immune system and plant hormone regulators. Bad decision? Should I cram them in?

    Lol I'd love an A, but i think i won't be able to remember what I have "learned."

    Em, spank, there was a short question on antibodies and antigens last year, I can't remember if there was more. Read over it before the exam tomorrow; its actually not too difficult a chapter. I'm leaving out plants, except photosynthesis and respiration so I don't know about the other thing.


  • Registered Users, Registered Users 2 Posts: 321 ✭✭Bluefox21


    lol i plan to learn respiration photosythesis genetics and the eye before tomorrow and I plan to watch prison break mission impossible :D:D


  • Registered Users, Registered Users 2 Posts: 699 ✭✭✭ashyle


    i'm leaving out all things to do with plants. sense organs-defo memorising that chapter its easy & has never come up. shiiiiiiite why did I do bio????

    I plan to fit it all in before 2 o clock tomorrow. Well some of it

    Can you leave out all plants?


  • Closed Accounts Posts: 108 ✭✭blondie07


    Im just doing the osmosis experiment now with the visking tubing. what kind of questions can they ask u on it? Why do u force out the excess air before you tie a knot in it? why do u wash and dry the outside of the tubes?

    Not sure bout the air part, put wud it work wit air in it? i dnt tink it does but anyways, n dryin it i tink its in case u spill some sugar outside the viskin tube.When u test the water from the beaker wit iodine it has to remain yellow/brown, to prove that only water went into the tube, nutin came out.

    Theres a question in one of the sample papers bout this experiment


  • Closed Accounts Posts: 428 ✭✭Selphie


    I think you have to dry it so that when you weigh it, you're weighing the proper mass of the thing, and not what it weighs when its dripping wet.


  • Registered Users, Registered Users 2 Posts: 427 ✭✭izzyflusky


    Yeah that makes more sense lol


  • Registered Users, Registered Users 2 Posts: 427 ✭✭izzyflusky


    Ok, here goes a stupid question...while do plants need nitrogen? Its asked in the nitrogen cycle n i cnt answer it!!

    Chemosynthesis isnt it?

    I think

    Nitrogen is needed in Plant Protein (coz the elements in it are C.H.O.N)


  • Registered Users, Registered Users 2 Posts: 427 ✭✭izzyflusky


    Dnt tink any1 is back yet. I live very close to my school and left early.

    In my opinion was a fairly easy paper. I was so worried all morning...Couldn´t believe when i saw photosynthesis there cuz i didnt tink i could be that lucky! Overall i´m very very happy. I got to answer 5 questions of part c n still finish an hour early :confused: But in general i always finish early so it dont really bother me.


  • Closed Accounts Posts: 1,504 ✭✭✭Nehpets


    I did all the questions. I didn't study the nitrogen cycle but threw something down and couldn't remember the thoraic volume/pressure stuff. The paper was pretty simple. I wasn't going to use bio for my 6


  • Registered Users, Registered Users 2 Posts: 427 ✭✭izzyflusky


    I am, but i can do wit a C. N i´d say i got that.So i´m very happy!


  • Closed Accounts Posts: 1,504 ✭✭✭Nehpets


    I can do with a C too :D


  • Closed Accounts Posts: 39 originalcupcake


    have to say i was delighted with that paper..even got a chance to check over everything at the end :)

    but what was that all about in the first long q...the rats DNA or something?? lol the department try so hard to be imaginative...:D
