It is often found in seeds and tubers (e.g.‚ potatoes). It consists of two kinds of polymers of glucose. The simpler kind is called amylose‚ and it makes up about 20% of starch. It is basically a chain of glucose units linked by α – 1‚4 – glycosidic bonds. During digestion‚ the oxygen

Plant cells become ’turgid’ when they are put in dilute solutions‚ which mean that it becomes swollen and hard. The pressure inside the cell rises‚ and eventually the internal pressure of the cell is so high that no more water can enter the cell. Turgidity is very important to plants because this is what makes the green parts of the plant ’stand up’ into the sunlight. However‚ when animal cells are placed in sugar solutions things may be rather different because animal cells do not have cell walls

The Ju/’hoansi from Southern Africa‚ subsist as the most documented community by means of where and how they obtain a variation of subsistences (Golden 103). Furthermore‚ the Ju/’hoansi hunt and gather near their campsites‚ which reside next to a watering hole (Golden 104). The Ju/’hoansi women can recognize about more than one hundred edible plants for the reason that they operate the gathering. In fact‚ the Ju/’hoansi women cannot hunt because other Ju/’hoansi natives would consider a women hunting

Plant Transport Plants are mostly made up of water. Lettuce is about 94% water and a potato is about 77% water. Plants need water for three main purposes: ------photosynthesis‚ -support -transport of chemicals Water is a raw material for photosynthesis. If water is in short supply‚ the rate of photosynthesis will be limited. Plants need water for support‚ otherwise they wilt. Water is needed to transport many chemicals within plants. Chemicals‚ such as mineral salts‚ dissolve in water and

Discussion: We have made four set-ups in two different specimens. Onion and Boat of Moses skin with water‚ 2%‚ 5% and 10% salt (NaCl) Solution. Based on our experiment‚ the result of the set up explains that the presence of the salt solution results in outward diffusion of water and the collapse of the protoplast. In table 1‚ we have observed under the microscope that the onionskin mounted with water has no results of plasmolyzed cell (0%). This time‚ we have repeated the procedure with 2% salt

Herinrich Wilhelm Schott who is one of the most important plant taxonomists of the 19th Century dedicated a large part of his life to the Araceae family. In 1832‚ he reclassified Arum colocasia as Colocasia antiquorum and Arum esculentum as Colocasia

The Isoma ritual is a corrective ritual used to remedy a woman’s inability to produce children‚ a condition commonly known as lufwisha‚ meaning “to give birth to a dead child” (16) as well as the “constant dying of children.” Lufwisha is thought to be caused by angry shades that inflict the condition upon the would-be mother‚ because she has forgotten direct ascendants as well as “the immediate progenetrices of their matrikin” (13). Isoma‚ therefore‚ is used so that the afflicted woman‚ being able
