ok can someone just explain to me these tables i see in all 3 biology books and other papers ive got.

heres whats some say:

Wind-pollinated plants:
Have no scent
have no nectaries

etc...

Insect-pollinated plants:
pollen is havoer
produce small amounts of pollen

etc...

i dnt undetstand what they mean :confused:

My teacher today explained it very fast, and i did not get all the notes down (first time :cry: :p)

thanks alot :)

i didnt do biology...

but i guess it seems to be a way of categorizing the plants species(?)

Pollination (http://en.wikipedia.org/wiki/Pollination) you may also want to look for: vanilla at wikipedia...

however, the article is wrong in one point. natural pollination of vanilla is not done by an insect but rather done by a hummingbird (kolibri) only.

pollination: how the pollen gets from the male bits of one flower to the female bits of the other

insects that land on the flower can carry pollen to another flower (insect pollination)

some flowers, the pollen is blown from one flower to another in the wind (wind pollination)

flowers that need insects to carry the pollen have to attract insects - they can do this by making themselves smell nice and producing nectar for insects to eat. Flowers that are pollenated by wind don't need to do this so they dont. however their pollen needs to be small and light to be carried on the wind, and also to stick to the female parts of flowers of the same species. The pollen itself in the dfferent flowers will be different depending whether it has to stick itself to an insect or be carried on the wind.

Hope that helps inshaAllah - what you wrote above is just shorthand for what I wrote
