We definitely know that the water potential of the solution is higher (less negative) because the plant cells were more turgid. Also, since the water potential of the solution is higher than that of the plant cells, water entered the plant cells by osmosis and increased the water potential over there (it made the water potential of cells less negative as well)

Oh well
In the xylem, it just moves upwards through the lumen.
However, as soon as water enters the endodermis, it must go through the symplast pathway.
The pathway which involves water moving through plasmodesmata is the symplast pathway.
Telophase is not right. because there are 2 nuclei which means that it has already divided!!!!!!!!!!!!!

ive seen it in a past paper it is telophase and btw for the membrane question, to put it in simple terms, 02 and co2 CAN diffuse thru the membrane so the function of the phospholipids is to allow the passage of these 2 gases, hence option a was wrong. the question asked what is NOT a property, but letting the gases pass thru was the statement in a, making it wrong and making the hydrogen bonds statement correct since only glycoprotien,glycolipid form h-bonds
telophase is right! & was a past-paper question!
So! A was the correct option????

How many mistakes have you all made? (out of the ones we've discussed)
That could give us a more accurate grade threshold for this paper...

no it was c according to me
Lol!!!! Dont know what would be the correct option? everyone has a new answer
I put the answer about cytokines, I think a lot of ppl did that too but idk what's right :sLol!!!! Dont know what would be the correct option? everyone has a new answer
Cytokinesis is when the cell itself is splitting in two (split at the contractile ring) which comes after telophase. Telophase is when the nuclear envelope and nucleolus are reforming.
Phsopholipids actually allow oxygen and carbon dioxide to flow freely through it. Although they are very slightly soluble in water, they are non-polar (oxygen atoms obviously have the same electronegativity, and carbon dioxide has two dipole moments which effectively cancel out since they're directed in opposite directions, so carbon dioxide is non-polar).

In telophase, the nuclear envelope reforms, the spindle fibres disintegrate & chromosomes uncoil. Division of the cell into two cells happens during cytokinesis.
So what did u answer for the phospholipids question??? Which one was not a function of phospholipids??
i picked A which was cytokinesis..... not sure whether its correct
10 of my friends wrote the same answer 'A'

That plant question: It was A. Both less negative.

I picked A too, it makes the most sense I think
