the set-up of expt:
select a stem with large leaves and insert into a tube under water without bubbles
the other end of the tube is connected to the pressure sensor of potometer
by data logging, the pressure change with time is observed under the 4 conditions. each condition allows 10min data...
I've done an experiment on rate of transpiration in 4 conditions.
1) ambient
2) ambient + fan
3) ambient + lamp
4) lamp + fan
result: the rates are
1) -0.367
2) -0.233
3) -0.197
4) -0.198
why the rate on condition 1 is the highest but not condition 4?
thanks for your reply.
you said lactose can be used to control osmosis, is that also happen in kidney?
what is the advantage of using lactose in breast milk with its low solubility property?
how about the galactose? what is the use of galactose in human?
hope to hear from you soon.
I would like to know the use of lactose and galatose in human with regarding to their solubility.
how does low solubility of lactose can be made good use on human?
what are the uses of galactose for human other than making guma?
