why sori on the underside of fronds?
149927
The fertile regions on fronds that bear sporangia are known as receptacles, and the group of sporangia on a single receptacle is called a sorus. In many species, but by no means in all, the sorus is covered during development by a flap of tissue called an indusium. The shape and arrangement of the sori are different in different species.\n\nhttp://www.bbg.org/gar2/topics/botany/repro_ferns.html

They can see farther out into the water from an elevated position. It also helps them see over the waves.

This is normal IMHO, and it sounds like you are doing a fine job. They also supposidly like having a regular dust and the old leaves being removed from the pot if applicable. I've looked after mine for over 7 years now; I still get the joy, heheh.\n\nTo start with, I found the plant grew very predictabilty upwards, loosing leaves slowly at the bottom for several years. Then after lobbing the top off a few times over the years (think carefully, and take a deep breath for this) buds for new 'runners' seemed to spring up even lower down, and it has become more tree-like; branching at the top.\n\n The 'leaning' towards the sun will likely be the trickey thing to manage!!\n\nGL :)

on the underside of the leaf.  they open and close to regulate the gases and water in the plant.  if it was on top, i think it could get damaged and be unable to regulate the exchange.

May have been picked and let ripen in sun like we do tomatoes lol. It could make it harder that when it ripens in sun own its own lol.

Because the roots are on the dirt which means in the bottom side...if you grew trees upsidedown you would be planting what actually grows and it wouldnt have enough oxygen...

it has to do with the depth of the ocean and how the sun is hitting it

the moisture settles on the thing above it.

It's me again, Dhinesh,your classmate.\nrolling frictin is the friction caused due to rolling. it opposes rolling & it acts on a single point as there is a single pt. which has contact with surface

because at that time it is below the horizon and its rays are reflected to us by different layers of atmosphere.while comoing to us it is diffused

Because they are full of air.  Buoyancy.

To give them more stability.  Their roots are not very deep so the tree could be top heavy when fully grown.  The base gives the palm bottom weight and therefore balances the top weight, especially when it is laden with fruit.
