What was the answer for the statements question about apoplast and symplast pathway? there was a statement that said water moves through the PLASMODESMATA in APOPLAST pathway so i i didn't choose this statement i choosed the other 2 statements ...

Don't remember all answers, think it was lysosomes and Golgi though
No, the one which gave that list of organelles such as nucleus, mitochondrion, etc & asked which one of them had a single membrane?
I honestly forgot that one :/

Yes that statement was rubbish. I think I chose the others too
HI 5. hope it's correct! what do you think of the GT?
Nope they dont have double-membraned organelles!
Hello everyone, I just came from school, and I've missed most of the discussions. If anyone's interested, here are the answers that I remember.
Actual size of cell = 50 micrometers
In prokaryotes, ER is absent and DNA is the genetic material
Lysosomes and Golgi apparatus have single membranes (2 and 3)
Prokaryotes are 750 nm = 0.75 micrometers on average (and I think that was option B)
Glycosidic bonds are broken down by dilute hydrochloric acid
Primary, secondary, and tertiary were affected
Heart graph: 1,2,4,3
Volume of oxygen exchanged per minute = 325 cm^3 ([19-12.5]*[5000/100])
Enzymes lower the activation energy required to start a reaction
Glucose and proteins have C=O (carboxyl) group
Water potential of solutions: both "less negative" (option A, I think)
Measels is spread in overcrowded conditions only (3 only)
Organism C increases in number
NPP = GPP - respiration

ohh that was easy ! it was golgi apparatus , lysosomes and ER ( not sure whether ER was there in the choices) but i'm sure it's not ( nucleus, mitochondria or chloroplast) since they have a double membrane

I think it'll be high cause the paper was quite easy. Around 33 maybe, or higher :/
32-34 i guess
ohhh god /: last year it was 35/40 for A . i'm scared it's the same again but i don't think it will be higher than 33 since there were many confusing questions ...

the second statement dint make much sense so i only chose 1
oh come on ! it wasn't that easy to reach 36 ! i don't think it will go beyond 33/40 . usually oct/nov has a lower GT than may/june

For the plant material placed in solutions of different concentrations, shouldn't the water potential of the cells be higher, and that of the external solution be lower in the concentrated solution and vice-versa for the dilute solution? :/
I either chose 1&2 or 1&3. I seem to be undergoing memory loss at the moment & can't confirm what I chose :/
It was a repeated question! The answer was A :|
