Fruits and Seed Dispersal

Fruits and Seed Dispersal Nicole Saylor Meiko M. Thompson BIO one hundred fifteen 11/25/12 In this essay I will be answering questions much or less fruit and as to the reason why things argon the way they are First up is some fruits are sweet and some are not is because, Actually, the taste of a fruit depends on the compounds put in it. Normally a fruit contains thematerialslike cellulose, proteins, starch, vitamins, certain acids,fructoseor sugar. All thesematerialsare found in mixed form inside the fruit and they have dissimilar proportions in different fruits.Fruits ofsweet taste have morefructosein themwhereasthefruits ofsour taste have more acids in them. (Gemini Geek) so this means that the more or less acid a fruit has thusly more sweeter or more sour it will taste, and that all means something with no taste rattling to is to say to have no acid , or sugars that would give it a particular taste. The next in line is that the ripening of a fruit and the spill dispersal go devolve in hand in such a way that when a fruit ripens it is a signal from production fashion of a seed to the dispersal of a ripe(p) seed that is ready to become another set out to create the dame cycle over again.To help explain this for example, n dry fruits (cereals, nuts, dandelions) ripening consists of vapor and is considered maturation. Ripening in fleshy fruits is designed to make the fruit appealing to animals that eat the fruit as a means for seed dispersal. Ripening involves the softening, increased juiciness and sweetness, and color changes of the fruit. Fleshy fruits are all climacteric or non-climacteric. Climacteric fruits produce a reparative burst with a concomitant burst in ethylene synthesis, as the fruits ripen. These include fruits with high degrees of flesh softening, like tomato, banana, avocado, peach etc. (Lecture 17)So we see that in this do of ripening and seed dispersal are that it is the plants way of making sure that the seeds that it produce d to carry on and make more fruit plants or trees happens by making the fruit itself more appealing to animals which will at and then later disperse the seeds. The next question to address is how do we play a role in all of this and how do we effect it basically. Well we humans affect this natural process when we take over the land and granted that plants were here long before we were and before animals were.So plants have been sufficient to grow without our aid if fertilizing the soil and etc For example, Unlike colonist plants, the deep forests of our planet are largely self-sufficing from us. They dont need us to prepare the ground or disperse their seeds. Plants, after all, colonised dry land well before animals did, and were doing quite well, on their own, before we arrived. Some kinds of trees need flyspeck help from animals of any sort. Because they dont need our help, these trees have little to gain by sustenance us. This is why we often find that there is relatively li ttle food to be had in mature forests.You cant eat wood. (Kyle Chamberlain) So see plants were reproducing before animals and us but granted when animals came on it did make the seed dispersal process a lot easier. As far as I can see that a seed does not use sugar or starch for its metabolic process unless it developing then yes. Because when a seed is developing it needs these to grow into a mature seed that can be dispersed, but since this seed has become mature and is dispersed then it start increment and producing its own sugars and starches from the light and dark process of photosynthesis.References The Gemini Geek (2012).
