I am not sure man. I think RBD cant pass thru the capillaries right?

iamapebble SG

Can't remember but I think is the one that do not have light has limiting factor since increasing light intensity do not have any effect on the plant.

davidche SG

The difference between X and Y(the one we drew) was that Y had more oxygen production before light intensity of 13.5. As the intensity increases, X had more oxygen produced, meaning more photosynthesis.

Evidently Y is the plant which is normally in shade because it is more adapted to surviving in darker places, because it has more photosyntehsis in lower intensity.

Kinda like why grass in direct sunlight are shorter.

Scotchtape SG

I put Plant Y too. shizz.

uponAStaR SG

I put Plant Y. Cos plants in shades dun get much sunlight. so not a lot chloroplast. blah blah blah..

Am i right??

Forevagalaxy SG

i think my answer similar to yours...

Theguiltshow SG

Wasn't the graph production of oxygen against time (and not light intensity)?

Theguiltshow SG

And I thought they said one plant was placed in sunlight, one was placed in shade. Then they gave you the graph and table values and asked you to conclude which plant was placed in the shade? Not which plant is normally found in the shade. Isn't it? Which is why limiting factor immediately popped into my head.

Forevagalaxy SG

ehh i thought there wrote oxygen production against light intensity?

iamapebble SG

The graph is oxygen production against light intensity. Not too sure about they put one in light one in shade, or one grow well in light and one grow well in shade. O.O But then if they are saying one was put in light and one was put in shade and they ask which was put in the shade, the graph wouldn't make sense since in both cases the light intensity increased, no?

Theguiltshow SG

Hahaha okay I have no idea, I can't remember much O_O

Going to study for SS now!

iamapebble SG

Hahaha okay I have no idea, I can't remember much O_O

Going to study for SS now!

Haha yup, let's moveeee on, me too :D Study hard people!

davidche SG

its light intensity for sure because i read from the graph that till light 13.5, play y always had a higher oxygen production. And i can also tell you that they provided no units for light intensity. They say arbitrary units. This is because while explaining the light i had to include units so i looked for what the unit is.

But this isnt impt. jie2 ai1 shun4 bian4

SS is coming. Guys got see my predictions?

La Nina SG

lol. 22 topics for bio. or 21? forget.

Anyway, this is new syllabus. You good in memorising doesnt mean u can do well. Almost all of the Section A is like application question.

I was tested on 20 topics and i studied the same syllabus as you guys and seriously memorizing helped me. Of course, you have to understand what you try to memorize as well. For the record, I scored 83 for my EOY examinations.
