Bio doubt:
Just wanted to know that why is glucose absorbed by the ileum through active transport and not diffusion? How is the glucose lower in concentration, I mean it isn't previously absorbed by any other cell before the food reaches the ileum then how does the high concentration of glucose that is ingested become less, (where does it vanish! :rolleyes: ) that it needs to be absorbed by active transport? o_O:confused:
Help!

THE ANSWERS ARE IN ORDER
prevents water loss and the effect of wind
prevents loss of water cuz its waxy u know water cant pass
very long roots to go deep into sand dunes an dget water and minereals
it stores water and as it is green it carrys out maximum photosynthesis
if there are less leaves there will be less chlorplast lss chlorophyll and less photosynthesis

osmosis-----------temperaure and no of root hair cells
photosynthesis------------light and temoerature
transpiration-------------temperature ans no of stomata

hope this helped remember me in ur prayers an dhit like

IS good questions
the glusoce ingested does no VANISH but say TRANFORMS into glycogen and is stored in the liver
and is again turned back into glucose for giving energy when the body needs it pancreas secert insulin hormone to do this
hope i am right and i helped cilkLIKE if did

so what you're saying is due to the fact that the stored glycogen can be converted to glucose any time and taken up by the ileum so there is always glucose available in high concentration for the small intestine and it never becomes low for the incoming glucose ingested to be diffused and not absorbed by active transport? :eek: Did I get you right? :rolleyes:o_O
Isn't there like a possibility that there isn't enough glycogen available for conversion and the concentration of glucose does decrease in the body and then there might be diffusion? :whistle:
