IGCSE BIOLOGY------>TRANSPORT IN PLANTS

Good night and good luck

Anybody interested in the contents of the human stomach and combustion should realise that fire is only a self sustaining  chemical reaction where the activation energy is provided by the reaction. There have been cases of "spontaneous human combustion"m where apparently the contents of peoples' stomachs have spontaneously combusted, maybe in the same way that rotting food in the sun can catch fire suddenly. The whole body can burn so fiercely as to be totally consumed in spite of being 70% water.

Wohoa, I am getting dizzy with all of these nauseating details up my head.

[sweetsh]

Oh gosh

[SGVaibhav]

hhhaaha


but an advantage is that during rotting, CO2 is produced, so it will act as an fire extinguisher.
:D
SIGN OF HOPE

but if are running or doing some heavy activiyty, then our muscle will respire anaerobically in that case due to absence of oxygen.
rotting in absence of oxygen produces methane(CH4) instead of CO2.
so now, ur fully charged up with methane.
and  if  there is even little friction, then
BOOM, THERE U GO

Mr. Paul is an good chemistry teacher also.

Back to real biology.

Any questions students??! 

[emi]

i had Questions in some past papers .. but i will post them later and separate since this topic is for Plants stuff ,, when i reach to solving past papers i will post it

[sweetsh]

yes please do.you can post them on the new topic 'IGCSE Help'

[SGVaibhav]

ok lets get serious now!!
no doubts so far,
 but i am trying to look for an video which shows how these auxins cause bending.

[saifalan]

Read abt auxin more than a year ago. Aint auxin a hormone that grows hair when u put it onto ur skin ??

[past-papers]

Doubt it. Auxin causes plants to grow taller by elongating the cells. Try searching auxin in wikipedia or google.

[saifalan]

I was being sarcastic   

[sweetsh]

Haha Im loving this forum more and more everyday.

Anyway saifalan didnt you take biology IGCSE? Auxin as past-papers said is a hormone causing plants to grow taller by elongating the cells..

[SGVaibhav]

ok   LAST FUNNY SENSELESS NON-SENSE  STUPID  IDIOTIC COMMENTING COMMENT

maybe he thought if he pours that in his hair, he will grow more hair. but he tried on his head and actaully

plants grew
removed all the nutrients from his brain.
de-nitrifying bacteria settled there.
there were few explosions

and at last the plants brain washed his head.

ok



NO OFFENCE!
JUST FOR FUN!


Time to get serious....

[sweetsh]

Good idea. Its better we dig our heads inside books as our exams are not so far away.

Best of luck for everyone
