Adam and Eva Essays

Adam and Eva Essays Adam and Eva Paper Adam and Eva Paper A man said to me once, that youll never realize the limits of time until you hit a certain age; the finite-news of it all. I still wonder each day what Ralph Williams really meant when he foretold me those queer words, while in the middle of discussing literary themes which has transcended through time. The Irony with this, I guess, Is why In my life are so many of the great themes Vive enjoyed, gone? Was he really forewarning me of this nostalgic tragedy we will face, or realize, one day? Has that day come for me? I often attribute the story of Adam and Eve with that of a typical relationship. A man Is young and carefree, enjoying his life In the fair Garden of Eden with a woman he enjoys to be with. With no of good or evil responsibilities ever haunting his naked, pure senses. But then Eve brings forth apple, Oh the Apple! What Is this apple you force me to eat, Eve? It Is this apple that steals away my bachelorhood! No longer can I roam naked around the garden and do as I wish, but rather I must now bare a child with you and toil the rough soil to support us all. Why, Eve, have you seduced me with this forsaken apple, which has stolen all the pureness and freedom away room? Is it really this simple apple, which I have now eaten that makes me see the tragic end? Is it this simple apple that makes me a man? Then what is so great about being a man? Oh cursed woman, why do you force me to eat such pain? To follow your rules, Oh I believe the wicked apple really is the downfall of all men, and the end to his glory. The moment in time, when that apple is handed to the man from the wicked woman who now takes control of his soul, chaining him to her and her ways.. Why are we made so weak to fall for such a tragedy after all these millenniums?

Tree Leaf Abscission and Cellular Senescence

Tree Leaf Abscission and Cellular Senescence Leaf abscission occurs at the end of annual plant senescence which causes the tree to achieve winter dormancy. Abscission The word abscission in biological terms means shedding of various parts of an organism. The noun is of Latin origin and was first used in 15th century English as a word to describe the act or process of cutting off. Abscission, in botanical terms, most commonly describes the process by which a plant drops one or more of its parts. This shedding or dropping process includes spent flowers, secondary twigs, ripe fruits and seeds and, for the sake of this discussion, a leaf. When leaves fulfill their summer duty of producing food and growth regulators, a process of shutting down and sealing off the leaf begins. The leaf is connected to a tree via its petiole and the twig-to-leaf connection is called the abscission zone. The connective tissue cells in this zone specifically grow to be easily broken apart when the sealing process begins and have a built-in weak point which allows for proper shedding. Most deciduous (means falling in Latin) plants (including hardwood trees) drop their leaves by abscission before winter, while evergreen plants (including coniferous trees) continuously abscise their leaves. Fall leaf abscission is thought to be caused by a reduction of chlorophyll due to shortened hours of sunlight. The zone connective layer begins to harden and blocks the transport of nutrients between the tree and leaf. Once the abscission zone has been blocked, a tear line forms and the leaf is blown away or falls off. A protective layer seals the wound, preventing water evaporating and bugs getting in. Senescence Interestingly, abscission is the very last step in the process of cellular senescence of deciduous plant/tree leaves. Senescence is a naturally designed process of the aging of certain cells that takes place in a series of events that prepares a tree for dormancy. Abscission can also occur in trees outside of autumn shedding and dormancy. Leaves of plants can abscise as a means of plant defense. Some examples of this are: dropping of insect-damaged and diseased leaves for water conservation; leaf fall after biotic and abiotic tree stresses including chemical contact, excessive sunlight, and heat; increased contact with plant growth hormones.
