Why do some palm trees have a huge bulge at the base of the tree?
931675
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.

Because the pulp ascent in the bottom

The effective weight of the pine needles, and therefore the branches would be increased.  Happens a lot in New England.  With enough weight, the branches fail to hold the weight , and break. Snow on branches also increases the profile of the tree , and high winds are more likely to blow it over.\nAre you going to get an A for my answer?

Because the tree is not a plum tree

The lines are like the arteries and veins in your hand. Carrying nutrients throughout the plant (leaves).

Cedar trees find it hard to propagate mainly because the soil can be too base or too acidic.  As the fruit of the ceder tree is so sensitive, if the soil isn't of the proper ph balance, the tree will have issues.

They are big boned, literally that is part of the reason.  Relitive to thier size they arent "fat" you dont see whales with huge stomachs... they're just HUGE

You have mentioned that your hands are getting bigger, but if your palms  alone gets bigger, then it signifies that you have some problem in your circulatory system( including heart), so kindly contact physiotherapist and a physician.

All palm trees belong to  the plant family Palmaceae or Palmae; these are all monocot flowering plants.A short list is given below. I hope is is helpful to you. :-\n 1)Cocos nucifera - The coconut Palm.\n 2)Phoenix dactylifera - The date palm.\n 3)Livistonia rotundifolia - The Fan palm\n 4)Livistonia chinensis(sinensis) - The Chinese fan palm.\n 4)Calamus flagellum  - The cane palm. This is not a tree like in habit(Appearance).It is a climber and the stem is the source of commercial cane.It is mostly used for fany furniture and other decorations.\n 5)Oreodoxa regia - The Royal Palm or the bottle palm. The trunk is distinctly bottle shaped. A very attractive Avenue tree.\n 6) Areca catechu - The betel nut Palm.\n 7) Borassus flaberifer - The Plamyra Palm. It is the tallest Palm amongst the family.\n 8) Caryota urens - The fish tail palm.\n 9) Hyphaene indica - Only Palm tree that shows branching.\n 10) Phonex sylvester - The Indian date palm.

A coconut, when it is removed from a coconut palm tree , is a fruit and a one seeded fruit at that.\nBotanically speaking it is classified as DRUPE . The greenish or yellowish skin is the outer skin of the fruit or epicarp ( epi = outer; carp = fruit); the middle fibrous part is the mesocarp ( meso = middle). This mesocarp , being fibrous, is the commercial source of coir fiber, many tropical countries are famous for it. The inner most part of the fruit is very hard, stony and shell like; it is the endocarp (endo = inner or inner most). It is because of this hard endocarp the fruit is called NUT. \n The fruit part ends with the endocarp and the seed part begins.\nThe edible part of the fruit, which well protected by the endocarp, is the SEED.\nWhen young and immature this part is mostly liquid, and very delicious liquid at that, and commonly called coconut water.\n As the fruit, or the seed if you like, matures the liquid part solidifies and turns in to ‘ copra’ in native language. This solid  copra has its own skin which is invariably Cadbury chocolate brown in colour. That is exactly  the skin or the wall of the seed and botanically  Testa, that is wall of a seed.\n The seed encloses a small embryo located just below one of the three distinct dark spots on the shell.\n It invisible and can be noticed only when the seed begins to germinate.\n The solidified and dry copra is the source of coconut oil of commerce. Botanically it is called endosperm.\n IN A NUTSHELL, A COCONUT AS IT FALLS TO THE GROUND IS A FRUIT.\nTHE FRUIT PART ENDS WITH THE HARD SHELL OR ENDOCARP.\nTHE SEED PART BEGINS WITH THE CHOCOLATE BROWN TESTA  AROUND  THE OILY ENDOPERM.\nFoot Note: - 1) The fibrous mesocarp is also known as the husk. Removal of this husk from the nut is    called Dehusking or simply husking of nut. The coir obtained from the husk has a number   of commercial uses. The chief among them is rope and mats.\n         2) Completely dry endosperm easily separates from the hard shell and has a spherical shape       and the size of a cricket ball. This is the real seed The dark brown testa is easily visible    in such a case.\n   The dry endosperm yields plenty of oil which edible, and has a score of cosmetic     applications. The solid residue that remains behind after oil extraction is very rich source    of proteins.\n         3) The hard shell is a good source of fuel and burns fiercely. In fact no part of the tree is    wasted. It is one of the Nature’s bounty to man kind.

Only one I can think of is the Palm Heart. It is the unexpanded vegetative apex that is vaguely heart shaped.

Common Burdock: Burs are much smaller and stalks are shorter (burs are closer to the stem); the stalks of the lower leaves are hollow, not grooved and the plants themselves do not grow as tall\n\nGreat: The burs are large - up to almost 4cm and the stalks are long; stalks of lower leaves are solid and grooved on the upper surface; grows taller in general

Yes if you mean total ARMSPAN. It happens in lots of normal folks but ocassionally it may be a sign of a heriditary medical condition such as Marfan's syndrome, where you have very lax ligaments and are predisposed to various heart conditions.

A canopy could also mean more trees. The more trees there are, the more they hold roots and soil in place, thus preventing erosion.

There are about 200 genera of palm trees (Arecaceae or Palmae) and approx 2,500 species (with complicated taxonomy). Identification of species is not simple, and it won't be easy to find a dichotomous key for _all_ the palm trees. If you're interested in general knowledge, try some specialized books. If you want to identify specimens, you should look for a local key for your area. \nSee the FAO site at the link, it could be a start :)
