As'salam u Alaykum. How did it go?

 

[sweet life]

how was yours? Which slide came?

what was the slide?

 

[Ikram Khaliq]

how was yours? Which slide came?

what was the slide?

transverse section of a plant leaf

 

[Usman04]

Mine was fine except Q1 one thing i want to discuss is thatin graph q the water pottential on y axis starts from -3 some were saying that we have start our graph from -3 because it is smallest value. is there anyone who had made the graph correctly

 

[Muhammad TAimoor]

No graph had to start from -1. You did right.
My q1 was like, the worst question i have ever attempted. It was real difficult understanding the quesyion and then completing it in time. I suppose I 've lost 8 straight marks

 

[Usman04]

thanks dude

 

[Manahil Shafiq]

mine went fine,though q1 took me a great deal of time.

 

[Ahmed Khalel]

question 1 went bad for me , i took 20 min. just to understand what to do , and i didnt use a syringe for the 5 test tubes just measured them roughly, hope the threshold be low.

 

[samiaaaaaaaaaaaaahhh]

what was the answer to that hypothesis ? was the statement that co2 decreses with time correct? or no? please help!!

 

[Nerd for Word]

what if my readings were wrong.. how many marks will the examiner deduct..
i was getting a decreasing trend.. for instance..
for reading 1 i got 175 seconds and for reading 2 i got 160 and for reading 5 i got 60 seconds..
probably the worst practical i ever did.. the slide went much better.. what do you guys expect the threshold to be..
i hope its somewhere around 24 so that i can score a B or a C..

 

[rabeeya]

Heyy
I was also getting a decreasing trend

 

[SOTZAIDI]

Worst Practtical Q1 of my life, My trend was variable and I did ot even had time left to write the hypotheseis Hope The threshold is Really LOw....

 

[rabeeya]

Hope for the best

 

[Ahmed Khalel]

its a decreasing trend , which means the statement is wrong and the rate of co2 getting produced is more.

What was the ratio of diameter of vascular bundle and width of xylem tissue?
I got 5:2

i got the same answer

the graph does start from -3 on the y-axis and goes up to -2, -1 and then 0.

 

[Ikram Khaliq]

it was not supported.

 

[Ikram Khaliq]

What was the ratio of diameter of vascular bundle and width of xylem tissue?
I got 5:2

i got 13:5. i was confused because there were two distinct vascular bundles seperated by a wall of cells. so i took the width across both xylem tissues rather than one. idk.
