Junior Cert Experiment-Biology

Blyngin

Hi I was just wonderin if anyone knew any good links to find information on the following experment: A gardener suggests that the lenght of time taken for marrowfat peas to germinate is decreased if they are soaked in advance. Carryout a quantitive investigation of this suggestion. Thanks;)

S.T.E.V.O

i was wondering the same thing. what date are you doing your experiment. i am so screwed.

Yes i am doin this experiment aswell.

What I've got is I put groups of peas in a number of labelled test tubes, don't soak one group and soak the rest for different times at different temperatures and then see how long it takes to germinate.

I hope that this will be enough to get me a pass. Can you help me anymore?

Doesnt have to be done at different temperatures btw

Geg124

Yes i realise that but wouldnt it be better to do it at different temperatures?

It would help, but I'm not sure that level is required for Junior Cert. It's moving into the realm of enzymes. If you are going to use temperature, make sure you've got one in cold water, one in warm (around 20 degrees) temperature and one very hot (over 40 degrees).

I dont think i will use temperature as it is getting into to much detail which wouldnt really be needed at this level as you have said. Thanks

Anyone have any luck finding helpful links? Ive spent ages on google trying to find something but I cant see anything helpful with the write up

Google it!

Well correct me if im wrong but your mother might be able to help you with this,

but what you can do is get 100 marrowfat peas. Divide them into groups of 20. i.e 5 groups

leave one group without soaking and record the time it takes for them to germinate.

then use the other for groups and soak them for different times!

i.e
1hour

4 hours

8 hours

and 24 hours.

and record the time taken to germinate


You might also want to be a nerd and try leaving some peas (after they have been soaked) in complete darkeness and see if the germinate!

hope this helps:)

Get 2 groups of marrowfat peas, 3 in each. Soak 3 for 24 hours. place the soaked and unsoaked in seperate jars in compost. leave in a temp controlled environment for 48 hrs. After that remove and measure any growth. The reason the soaked peas grow faster is that they absorb most of the water needed for germination before being placed in the jar.
u doing the ball experiment too?
