How come its the central part??

 

[Diishiik Douw]

i got magnification x0.8
i dnt know if its gOod but some pupils drew it the same size

 

[mimmi]

Omg I missed the question asking to fill in the missing number! This is so sad everything else according to you guys are correct

 

[mimmi]

I got magnification 1.9x

And wrote the factors as: light intensity, temperature, humidity

 

[Diishiik Douw]

the last question on hydrogen carbonate.
was it acidic or alkaline?

 

[Diishiik Douw]

i wrote humidity ,On a windy day..and hOt day..
gosh ! i got it wrong !

 

[mimmi]

 

[Prince III]

i got magnification x0.8
i dnt know if its gOod but some pupils drew it the same size

this is quite small and i dont think this much would be accepted !
i got my magnification 1.99 x

the last question on hydrogen carbonate.
was it acidic or alkaline?

please refer to previous post i have already told about it

i wrote humidity ,On a windy day..and hOt day..
gosh ! i got it wrong !

this is correct dont worry

factors were numerous
-temperature
-wind
-humidity content
-light

Firstly,i drew the same central part and labelled the radical correctly but didnt labelled the stem part correctly
how many marks would be deducted

SECONDLY, i cant believe my magnification was same 1.99
But the problem is i forgot to put "X" after the value would mark be deducted ?

 

[mimmi]

the diagram CIE gave for the exam had a magnification of 0.75x meanin the real seed would have been actually bigger. Also, we were suppose to find the real side of the part we were suppose to draw from the diagram! i got 31mm as in the diagram! so...

0.75 = x/31

so x = 23.25

then find the size of your drawing and divide it by 23.25

thats for 4 marks

answer me mimmi or prince

i dont think they will sorry not sure!

 

[mimmi]

hey guys, i labelled it:
this part develops into stem ------>
this part develops into root ------->

would i loose marks?

 

[Shiki Misaki]

@ mimmi: No marks will be deducted.


Edit>> @ rose: 1 mark will be lost since you haven't precised which part would be the stem.

For the magnification, mine was ' X 1.1667 times'
and the reason why the graph was lower at 14 00, i wrote that it was due to high humidity.

 

[jazzangel16]

I drew the same thing!!.. But they are telling that we need to draw the smallest one???

That part is supposed to be the cotyledons huh?

 

[jazzangel16]

Some one please tell me what exactly we should draw for the magnification !!!

 

[Shiki Misaki]

These were included in my drawing too, except for the plumule part...

I'm 100% sure that small thing is air space between two cotyledons as it is a cross section of the seed =S

 

[Shiki Misaki]

@ mimmi: I guess you're right 'cause the seedling cannot be that small and besides the radicle was already there in the image.

If however I'm wrong, then what is the thing that I'm mistaking for the radicle? :S

 

[mimmi]

There is no other feature in the small thing =S

And the biggest thing looks like the fruit to me
