Whos been -repping me.
What did i do??!

hello little girl... r u ready?

im sorry but that just sounded wrong

thank you could you explain q. 27 june 2005

the answer is D BECAUSE plant bends toward the light that is positive phottropism
and the invertebrates is in dark place which is negative phototaxis

[kam]

can someonle tell me

if u increase humidity and temperature etc

will the rate of transpiration increase?

[AS girl]

Increasing humidity=decrease transpiration
increasing temperature (not to much)=increases transpiration

[Bani]

Someone, please answer my question....

[kam]

Increasing humidity=decrease transpiration
increasing temperature (not to much)=increases transpiration

thx

It is D. This is because when Invertabrated move away from a light source, this is negative phototaxis.
When a plant bends towards the light, this is positive phototropism.

Also, remember that when invertabrates respond to chemicals, this is called Chemotaxis
When they respond to gravity, this is geotaxis

[kam]

its B cuz leaves are green due to photosynthesis
its short cuz its too cold to grow
enzymes are not at their optimum

[AS girl]

please help:O/N 2007, paper 1, Question No.29
And can u please tell me the reason the answer is not B, because I  think since there is light, the plant should bend, as auxin will be destroyed....

It has nothing to do with auxins..5 degree celsius is a low temperature..so enzymes are inactive..rate of photosynthesis is low so the plant will grow but not that high!
the answer is B By the way!

Hope u understood my explanation

Oh I meant why is the asnwer not D....So its because it says the colour of the leaf is yellow, but in B its green.
So, since photosynthesis is happening in B, the colour is green, and thats why the asnwer is B
Ok, thanks, +rep
