dont u knw any thing abt v1 ???

62

what kind of drawing came to u?

 

[asd]

first question will be on 12 leaves of which 6 were kept in light and 6 in shade. leaves in light were smaller, and in shade were bigger. widths are to be measured and recorded in the given table, we have to find the mean also. The second part asks to extend the experiment further. Third part gives you cross section of both leaves and asks you to write down the differences and how these helped them in adapting to their environment.

Second question is on sensing the pin. they have 2 pins attached to a cork and they place it slightly on the student's skin at diff places like finger tips, forearm, etc. they ask you which is the most sensitive and which is the least and the reason for your answer.

In the third question they ask you to draw the granule in the cells of a tuber which will be shown in a photo. Calculate the magnification of your drawing.
then comes the food tests, their colours and conclusion.

The last question is on meosis, cell division and they ask you to label chromosome and cytoplasm in the picture.

help me plz

 

[asd]

I DONT KNOW ABOUT VARIANT 1 ok. IT's ABOUT V2.

 

[nehaloo]

hw to extend the exp. and wt were the differences and hw did they help too??
which is the most sensitive and y??
and wt was the q. abt meiosis and cell division?? :/
(actually Iam takin another varient but Iam just curious enough to knw abt it! )

I wrote to place the shade developed leaves in light and observe changes and record.
other possibility could be to take more leaves of the same type and test for starch in leaves kept in light and in shade. Compare and record the results, how can these differences be related to light.

differences were regarding palisade cells, chloroplasts, air spaces, and thickness. I wrote that shade leaves don't photosynthesise much so they take up less water and therefore less transpiration takes place. So, less air spaces allowed for less surface area and hence, less evaporation. Shade leaves had abundant chloroplasts in palisade cells, this was to make use of even the little light they receive for photosynthesis.

Fingertips most sensitive, forearm least because more touch receptors in finger tips.

What type of cell div. takes place in gametes, what is its importance? give example of a part of a plant involving meosis.

 

[nehaloo]

aha

 

[Zeus]

What did you give as a precaution for test of carbohydrates ? Ohh, and what did you give in the observations, second part ?

 

[tribianni]

VARIANT 1 any1 done wid it ???

which varient is it ??

 

[Zeus]

We can discuss it in conversations, can't we ? Anyone up for it ?

 

[nehaloo]

which varient did u take??

 

[Zeus]

Variant 62.

 

[nehaloo]

so Iam not involved in the disscussion cause Iam 61 :/

 

[nehaloo]

Just one q wht is the example of the part of plant in which meiosis takes place?

 

[Hamzeh S]

i think anther or style and stigma not sure

 

[asd]

can be anther/ovary.

 

[asd]

aha

atleast like the big post i made for ya! -_-

 

[Ali gaber]

atleast like the big post i made for ya! -_-

thanks man really appreciated but many people told me the drawing is gonna be an ants head
