Mimosa Pudica
TOUCH ME NOT PLANT
Mimosa pudica also called sensitive plant, sleepy plant and the touch-me-not,is a perennial herb often grown for its curiosity value: the compound leaves fold inward and droop when touched or shaken, due to evolution from predators, re-opening minutes later. The species is native to South America and Central America. but now It has been introduced to many other regions and is regarded as an invasive species in Tanzania,SouthAsia and South East Asia and many Pacific Islands.[7] It is regarded as invasive in parts of Australia and is a declared weed in the Northern Territory,[11] and Western Australia although not naturalized there.[12] It has also been introduced to Nigeria, Seychelles, Mauritius and East Asia but is not regarded as invasive in those places. It grows mostly in shady areas, under trees or shrubs.
Mimosa pudica is well known for its rapid plant movement. Like a number of other plant species, it undergoes changes in leaf orientation termed "sleep" or nyctinastic movement. The foliage closes during darkness and reopens in light.[4]The leaves also close under various other stimuli, such as touching, warming, blowing, or shaking. These types of movements have been termed seismonastic movements. The movement occurs when specific regions of cells lose turgor pressure, which is the force that is applied onto the cell wall by water within the cell vacuoles and other cell contents. When the plant is disturbed, specific regions on the stems are stimulated to release chemicals including potassium ions which force water out of the cell vacuoles and the water diffuses out of the cells, producing a loss of cell pressure and cell collapse; this differential turgidity between different regions of cells results in the closing of the leaflets and the collapse of the leaf petiole. This characteristic is quite common within the Mimosoideae subfamily of the legume family, Fabaceae. The stimulus can also be transmitted to neighboring leaves. It is not

    When plant cells have adequate supplies of water, the water eerts a pressure, known as trugor pressure, against the cell walls. This pressure supports the stem and leaves. IF MORE WATER IS LOST FROM A PLANT BY TRANSPIRATION THAN IS REPLACED THROUGH THE ROOTS, THE CELLS LOSE TURGOR PRESSURE.…

    In a flowering plant, the water travels from the soil, then to the root hairs, next to the xylem, then into the stomata, to the mesophyll cells, next to the stoma, then finally into the atmosphere. Osmosis is the diffusion of water through semipermeable membranes. Transpiration is the evaporation of water from the leaf. Cohesion is when water molecules stick together. Adhesion is when water molecules stick to, not attract. Root pressure is force made by root on water columns. Water potential is the negative pressure in leaves, which is positive in roots.…

    “Body Rituals Among the Nacirema”, by Horace Miner, is an essay written about the American people, from an outsider’s perspective, which he calls Nacirema, American spelled backwards. He disguises what he’s talking about by spelling many nouns backwards and giving things different names. Miner writes about American rituals in a foreign way that comes off as barbaric and heinous. He starts off talking about George Washington and how he founded America and how he’s seen as a hero. Then he moves on and talks about how vain the American people are, their focus being on money and the way they look. How the majority of people spend a good amount of time in the bathroom, which he calls “shrines”, prepping ones self to look different than they naturally do. How the richer you are, the bigger the house you live in and the more bathrooms you have. Then he goes on to talk about our medicine cabinets and says they’re full of “medicines and potions”, in which people believe they can’t live without. He talks about our doctors, dentists, and psychologists and gives them the names of “medicine men”, “holy-mouth-men, and the listener.” He even goes as far as talking about hospitals and what goes on there, which he calls “latipso”. He also talks about our dentist visits and our obsessions of keeping our mouths cleaned. Miner made his point quite clear, you can’t make an assumption or judgment until you have participated in another’s ways or “know the whole story”. It’s completely rude and demeaning.…

    The movie “A Wrinkle in Time” is better than the book because it doesn’t add extra useless information like the book does. There are some, but they’re minor. On the first page of the book the narrator says, “Sandy and Denny's, her ten-year-old twin brothers, who got home from school an hour earlier than she did, were disgusted.” In the movie, these characters were not in the story and it had no effect on the plot at all, making the movie better because it does not add useless excess information. This is declaring that in the book Meg was the oldest of 4, and in the movie there was only 2.…

    At first glance, it might seem that culturally-advanced and deep-thinking Americans have relatively little in common with the comparatively narcissistic, shallow, and primitive Nacirema, who carve out an existence somewhere between "the Canadian Cree, the Yaqui and Tarahumare of Mexico, and the Carab and the Awawak of the Antilles" ("Body Ritual among the Nacirema, p. 1). Who could even think to compare Americans, in our advanced state, with such a remote and isolated group? However, upon closer reflection, however, it occurred, much to the present author's surprise, that the Nacirema and Americans are in fact mirror images of one another.…

    We believe that when a plant is exposed to stress it will undergo morphological changes, known as thigmomorphogenesis, to conform to its environment. The purpose of this experiment is to observe the growth in Phaseolus vulgaris (common beans) with an emphasis on the structural changes induced by touch. During an 18 day observation period, the experimental group’s shoots and leaves were gently rubbed five times daily with gloved hands. After soaking in distilled water to hasten germination, the beans were planted in two separate 8 oz. cups filled with 4 oz. of topsoil. The soil was moistened with 1 oz. of distilled water and the cups were placed on a windowsill with sufficient sunlight. Each plant was watered at the base of the shoot daily…
