I know why plants have flowers but, why do some trees have fruit. How does it benefit the tree?

It is not the fruit which is beneficial to the tree. What is important to the tree is what is held within the fruits pulp or meat, the seed. Though the meat and or pulp of the fruit provide nurishment to all types of creatures, the real mission of the fruit is to protect the seed until it is ready to grow.





Thank goodness for the fruit though because it certainly provides...

FlowersBirthday FlowersSympathy FlowersAll flowering plants (angiosperms) produce flowers and fruits. Fruits develop from the ovaries of flowers and function in seed dispersal. Fruits may be juicy sweet and brightly colored to attract an animal disperser. Alternatively, they may be dry for wind (dandelion fruits; maple fruits) or water dispersal (coconut). Some fruits are barbed for animal dispersal (Burs)
Reply:Yep, animals eating the fruit to disperse seeds are how the tree benefits. Interestingly, the seeds of some fruits cannot germinate unless they pass through the digestive tract of certain animals. The acid in the stomach is needed to soften the outer coating of the seed to allow germination.
Reply:it%26#039;s their way of reproduction. all plants that have flowers eventually will get seeds from those flowers, i.e., they%26#039;ll bear fruit.
Reply:A: Because we live in the best of all possible worlds. The trees exist to benefit you and me. (Panglossianism)


B: Because farmers propagate, tend, and protect fruit-bearing trees. (Economics)


C: %26quot;Whatever, in happening, causes itself to happen again, happens again.%26quot; (Douglas Adams)


A tree which surrounds it%26#039;s seed with fruit has it%26#039;s seeds swallowed by browsing animals, such as horses or primates, who travel miles away before depositing the seeds, in a pile of high-nitrogen waste, on the ground. It is surrounded, one season per year, by fertilizer-producing animals. Thus fruit-bearing trees are well-fertilized and widely distributed, both when sprouting and when being harvested. These mechanisms, of course, are just guesses. How would you determine whether these mechanisms are actually causative?


Are wild fruit-trees more common in forests with relatively low soil-nitrogen content? Does eating lots of fruit cause diarrhea? Is there any fruit tree whose seed is destroyed by eating the fruit?
Reply:They use animals to spread their seeds. Offer fruit to a monkey (for example) monkey comes along, eats the fruit, wanders off to another part of the forest... poops - and therefore you have the seeds which are unaffected by digestion deposited with a healthy dose of manure. Genius - people have suggested that the banana is proof of creation - in fact it slots neatly in to evolutionary theory - the fruit monkeys enjoy eating less are going to have an advantage as its their seeds that will be propagated more often and more widely.
Reply:Birds eat the fruit and seeds then fly away and crap out the seeds, thus pollinating other areas.nanny
