In an eukaroyotic plant cell the mitochondria is contained in the nucleus. The mitochondria are the "power plants" of the cell. There are three main classes of plant cells: Epidermis, Vascular tissue, and Ground tissue. The second type transports materials through the plant. Since the plant is larger, being a tree, perhaps the longer distance means the cells need more mitochondria to travel that longer distance. In a bush this would not be neccessary. The third type peforms photosynthesis and does starch storage and stuctural support. These types are further broken down into Parenchyma, Collenchyma, and Sclerenchyma. Since it is a larger plant and more starch needs to be stored, perhaps this explains it. More powerhouses would seems to me to be a benefit in greater starch storage for a larger plant. I did not know there could be more mitochondria in one plant cell than in another. Your statement was the first I'd heard of it.

Mango trees grow best in soils with pH values of 6 to 7,2. If the soil-exchangeable aluminium (Al) is not more than 30 ppm, soils with a pH of 5,5 or higher may be used. \n\nAt pH values lower or higher than 6 to 7,2 the trees may suffer trace-element deficiencies, especially phosphate and potassium. \n\nFor acids and and nutrients of Mango see\nhttp://www.thefruitpages.com/chartmango.shtml

(m)\n\nMalaysia is well-endowed with rich and renewable natural tropical forest resources. The total area of natural forests in Malaysia at the end of 1989 was estimated at 19.49 million ha or 56.3 percent of the total land area. The total growing stock of all trees of 10 cm DBH or more was estimated to be 4600 million m3 of which about 1280 million m3 were considered to be merchantable volume comprising all trees of 45 cm DBH or more. Besides providing direct benefits, the forests play a vital role in maintaining environmental stability and quality; protecting soil and water resources; conserving biological diversity; and preserving cultural, recreational and other intrinsic values which enhance people's quality of life. \n\nThe importance of the natural forests to the Malaysian economy and the people's welfare was reflected in the early establishment of the Federal and State Forest Services, the forest research and training institutions and the National Forestry Council. National and state forestry policies and legislations have been adopted, Totally Protected Areas and a Permanent Forest Estate (PFE) established and forestry practices, based on the concept and principles of sustained yield, developed for sustainable forest management. Currently, the PFE comprises 12.73 million ha or 38.7 percent of the total land area and will eventually be increased to more than 14 million ha. Approximately 10 million ha or 78.5 percent of the PFE have been identified as production forest to be managed sustainably. In addition to the PFE, 1.06 million ha have been reserved as Totally Protected Areas and a funkier 0.75 million ha have been proposed for reservation (Thang, personal communication, 1991). \n\nCurrent forest management practices \n\nThe natural forests in Malaysia are managed in accordance with the concept and principles of sustained yield for all forms of forest produce. Traditionally, they have been managed under the Malayan Uniform System (MUS) which prescribes the removal of the mature crop in a single felling of all trees down to 45 cm DBH and the release of selected natural regeneration by poison girdling of defective relicts and non-commercial species down to 15 cm DBH (Thang, 1990). Approximately two to five years after the final felling, a post-felling forest inventory or diagnostic sampling is carried out to determine the stocking, status and condition of the regeneration and to prescribe appropriate silvicultural treatments. \n\nSelective harvesting of dipterocarp forest in Malaysia \n\nAs the MUS relied mainly on seedlings and saplings to form the next crop, silvicultural treatments were designed to favour these groups, often at the expense of the bigger trees. Such treatments tend to lead to a much heavier poison girdling than is necessary and, in some cases, a too drastic opening of the canopy. Consequently, the MUS has been substantially modified over time, with a shift toward more selective felling and the retention of advanced growth as well as a more discriminating use of poison girdling as a silvicultural tool. \n\nThe MUS has been applied successfully to the lowland dipterocarp forests but has been found to be unsuitable in the hill dipterocarp forests because of the more difficult terrain; uneven stocking; lack of natural regeneration on the forest floor before logging; uncertain seedling regeneration after logging (caused by irregular seeding); danger of erosion on steep slopes; incidence of the stemless palm (Eugeissona triste); and other secondary growth favoured by a drastic opening of the canopy (Thang, 1990). The shift from the MUS toward a more conservation-oriented approach to the management of tropical forests in Malaysia was also prompted by the realization that the diversity of the flora and timber species need not necessarily be disadvantageous to future wood production policies and strategies but could enable the wood-based industries to take advantage of changing demands of the timber

Most detergents have already reduced phosphate levels to below requested minimums. I think you have a stale worry and need to upgrade your worry list.

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.

through the roots and branches of the tree...teh same way that a orange has juice inside....coconuts have their nmilk inside.  the water pulled from the roots of the tree is distributed into the fruit as it grows

"High levels of Mn (189 and 465 ppm), Cu (30.5 and 21.8 ppm), Zn (151.9 and 75.1 ppm), and NO3 (4,600 and 7,200ppm) were found in the leaves of E. hirta and P. amarus respectively. No traces of cyanide and nitrite were found in the leaves of these two plants. Varying proportions of Fe (2,225 and 1,563ppm), Mg (5,500 and 5,800ppm), K (33,000 and 32,000ppm), Ca (21,000 and 26,500ppm), and Na (558.1 and 125 ppm) were found in the leaves of E. hirta and P. amarus respectively. The levels of chemicals are high enough to constitute a source of toxicosis to animals consuming them and their use for medicinal purpose should also be a source for concern most especially if the fresh leave decoctions are used."

The paddy soil-rice system has efficient nutrient replenishing mechanisms. Basic cations and silica are supplied by irrigation water, while biological fixation works as an inexhaustible source of N in the system, and phosphorus availability is enhanced under anaerobic conditions. This, along with almost perfect resistance to soil erosion, gives the paddy rice system high productivity as well as high sustainability.It has been shown that of the three essential macroelements, two of these, K and N, have an assured, if not sufficient, supply mechanism in paddy soils.Phosphorus has no such supply mechanism. However, it is the 11th most abundant element in the earth's crust, and is present everywhere in the soil in reasonable quantities. Therefore, what matters usually is its availability rather than the absolute quantity present. In acid soils in a humid climate, P is present mainly in the form of iron phosphate (Fe-P) and aluminum phosphate (Al-P). Neither of these is readily soluble. There are, of course, organic forms of P that may be released during the process of organic matter decomposition. However, in contrast to N, the quantity of such organic P compounds is normally very low, compared to the mineral forms of P.In the process of anaerobiosis in paddy soils, iron phosphate tends to be reduced, with a release of some of the P in available forms. Moreover, reduction of iron oxides releases some of the occluded P into the soil. Thus, there is at least one mechanism to raise the availability of P in paddy soils. The reduction of paddy soils under submerged conditions is accompanied by an elevation in soil pH. This is the result of H+ consumption as oxidized materials, such as NO3- and Fe2O3, are reduced. Usually the pH of acid paddy soils stabilizes at around 6.5. The rise in pH enhances the solubility of iron phosphate and aluminum phosphate, by a factor of 10 times per unit rise in pH.

try where sodium phosphate came from or what does sodium phospate come from .  Check it out

plants use N, K and P to live. the more phosphorus(phosphate) in the water the more plants it can support. the more plants the less oxygen for fish.\nso high phosphate levels can cause low oxygen levels.
