Was the answer "fats" or "Water" in biology paper 1 ?

Also the question of the arrows was tricky ..

i think it was fats cuz fats cnnot be found in plants!

Green plants can make all the materials(including fats and sucrose)using water,carbon dioxide and salts. They r synthesized from sugar molecules and other molecules produced in photosynthesis.

Glucose and amino acids are transported in solution(water). Fats are synthesized for cell membrane and for storing in seeds.


SO THEY LACK FATS

for sum reason.. I chose water... cuz a phloem tube transports amino acids and sucrose, and the aphid only fed on phloem tubes.... and why would a Aphid even need fats?
Title: Re: Was the answer "fats" or "Water" in biology paper 1 ?
Post by: thukon on June 06, 2009, 12:49:55 pm
The question was what do aphids LACK in their diet. Thats fats, because the phloem doesnt transport fats.

was it D or whichever one that was from decomposers to plants?

i did water...i don't think they lack fats they don't really need it.....so i think it is water.
Title: Re: Was the answer "fats" or "Water" in biology paper 1 ?
Post by: bebo26 on June 06, 2009, 01:12:58 pm
the aphids question definitely lacked FATS.. cuz the question asks: which type of food did the aphids lack and water isnt a type of food but fats are.

for the water arrow question, the answer was the one at the stomata bec water never enter the plant thru stomata, instead it only enters thru the roots.

X was the right atrium and W was the left atrium.. so if u chose W and X, u would be sayin the 2 artria contract together

there's something called an atrial and ventricular systole. Both the atria contract together and both ventricles contract together. So it's A

Post by: Bani on June 06, 2009, 01:51:33 pm
I chose sucrose, because, I think that they meant what does it lack in diet, as in it will eat what it lacks....so since it feeds on phloem tube, and the phloem translocates sucrose, thats what it must lack, as it feeds on it and needs it.... ???
I hope im right :-\
For the heart diagram, I chose X and Z (left atrium and rigt ventricle)
For the arrow question, I chose B (stomata)
For some unknown reason, for the  chloride paper question, I chose Plant Y, upper surface (on the chart, the highest bar<<<I thought tht the one tht takes the most time to turn pink loses water rapidly, as absense of water would not turn the chloride paper pink :-\

Hmmmm.... :-\

ya, arteries and veins is right...
I wrote sucrose(Aphids will eat what they need <so since phloem translocates sucrose, thats what Aphids must lack, therefore they feed on that>) :-\ Im not sure if Im right

No

Its A for the heart beating


Cause there is something about Atrial Systole that u have to know

Atrial systole is the contraction of the heart muscle (myocardia) of the left and right atria. Normally, both atria contract at the same time.

I think is the highest bar (bec the plant that took the most time to turn the paper pink meant that that water was lost rapidly, so absence of water did not turn the paper pink)

um u guyz even tho phloem transports amino acids and sucrose they CANNOT be travelling in " solid form" u cant hav amino acids travelling in a line along the tube they HAVE TO travel IN SOLUTION so they definitely get water.....fats are wat lack nowhere in a plant are ther fats, so answer has to be fats..even my bio teacher sed so

FAT IS NOT A FOOD
answer is water
neither is water!! fat is closer..lol
nehow...everyone cirlced fats..
and for the hear diagram...it was W and X...cuz they both contract and push the blood downwards to the lower to chambers to recieve while they r relaxin...thn they contract while the atriums relax and the blood is forced through the arteries...

no that is wrong presence of water turns the paper pink and as the leaf looses water by transpiration the faster the water lost the lesser the time taken because the water would escape through the styoma in the form of vapours which will be absorbed by the paper so it will turn pink therefore the lowest bar is the answer.its their in the mckean txtbk

You eat food right?
The food also contains water even if it is in a little amount right?
So why do you drink water?
So i think its water they lack in their diet.

Besides the aphids wouldnt want to become obese.

The aphids lack FAT!!!! Its common sense. When you break a plant in half, watery stuff comes out meaning that the plant transports WATER!!
The surface of the leaf that loses water the fastest is the one with the LOWEST BAR!! The lowest bar means it took the least time to turn the paper pink, which means it gave out water the fastest.
The heart one is the 2 atrioles, or W and X, or answer A.
The monocot leaf is D, the long thin one.
The energy flow diagram is D, the one that goes from the decomposer to the plant.
The last question.... I have no idea. I put B :P. BUT ONLY ONE WRONG SO FAR WOOHOO!!

Ok look guys think about it, what is sucrose?
Its a carbohydrate
What happens to sucrose when its is changed by enzymes
It becomes an individual glucose molecule
What happens when an organism (An Aphid in this case) has an excess of carbohydrates
They are stored as Fats
And so if the aphid is eating the phloem it will rightly obtain sucrose
Which can than be stored if in excess as fats
Thus meaning that fats cannot be the answer
Allowing us to conclude through elimination of the obvious first two and now Fats
That water is to be lacking.
Am i right... Think about it  ;D

Nice Explanation but dont think so
glucose can be changed into glycogen and stored :P
And what if it didnt feed on excess of carbs?!!!

its definitely water.. :)
isnt fat immobile..?
wat wud it be doing in the phloem?

it shud be water i guess...

wat say guys..?  ???

water cannot be lacking cuz all substances in phloem are transported in a solution. Plz don't repeat the mistake again in ur paper 2morrow.

Yeah true but the question clearly states that the contents of the phloem are all that the aphids eat
So therefore we know that it is eating usually excessive amounts of carbs thus justifying what i said.
Yeah but glucose is only changed into glycogen as a means of homeostasis, thats a completely different answer or even question
And plus isn't it the xylem's job to carry water and minerals.
Sucrose can be used as a transporting agent for amino acids.
Think about it Haven't you ever felt a sticky substance when you cut open a leaf, if you haven't try it.
So what i am trying to say is fats are just basically carbs stores assuming as said before that aphids are only eating the contents of the phloem as the question states.  :)

Ppl listen:
the aphid feeds on the phloem's contents, that means it obtains sucrose and amino acid. Done!
it cudn't POSSIBLY be lacking water in its diet cuz it would die (of dehydration or whatever). Done!
so obviously the answer is fats.

I know we r all trying to justify what we wrote, cuz obviously we  dont want to know our thinking was wrong ! :P
p.s. i chose amino acids not fats By the way

haha ok

Then the answer was fat beacause water is used as a solvent for amino acids and sucrose and not because it is not foods??

No one said it didn't drink ANY water, were just saying that it was LACKING water
So therefore it would still have blood.... don't freak out  ::)
What were saying is that water is not transported in the phloem
Only in the XYLEM (And please don't bring up that solution stuff again)
Sucrose can be turned into fats if it is in excess which in basically is
As the APHIDS are feeding on it constantly :)
Title: Re: Was the answer "fats" or "Water" in biology paper 1 ?
Post by: VIP_93 on June 09, 2009, 08:50:06 am
ofcourse guys it's fats
although phloem doesnt transport water alone but how could sucrose and amino acids ever be transported in phloem if they're not found as a solution? as powder??? as crystalline solids???? ofcourse not
and remeber that an importance of water is that it is a transport medium so everything is transported in it.. no matter what the phloem transports , water has to be in there. ;)

And By the way, phloem does transport water. Check your textbook people.

um sorry but u r wrong cause the answer is fats i asked my teacher and she said it is fats because the food  is dissolved in water and then transported in the phloem so the aphids get water!so it is fats :P
