where there is a high concentration of water to where there is low until both sides are equal. This is known as reaching equilibrium. A cell is turgid when it swells to its maximum volume due to large water content. Opposite to this is plasmolysis (or flaccid) where there is not enough water in the cell and the cell membrane begins to contract. Image courtesy of the BBC website. Factors which affect osmosis: The difference in concentration affects the speed ay which osmosis takes

Trade became the vehicle for the spread of religious ideas‚ technological innovations‚ disease-bearing germs‚ and plants and animals to regions far from there places of origin. Trade also shaped a lot of societies‚ whether it was politically‚ structurally‚ or economically. Economically it often altered consumption‚ for example enabling West Africans to import scarce salt‚ necessary for human

AbstractDifferent pH level may affect the growth and development of the plants. Certain key words include: pH level‚ germination‚ acidity‚ osmosis and diffusion. This experiment examines the effects of different pH level of vinegar on the growth of bean plants. Materials used in this experiment consist of: water (pH 6)‚ vinegar with the pH level of 3‚ 4 and 5 (each one were made before experiment)‚ beans‚ soil‚ and pots. Eight bean plants were planted‚ two were watered with pH 6 and the other ones

This would result in the potatoes’ cells shrinking-when the fluid left the vacuole‚ and the cytoplasm also being pulled away from the cell wall by the vacuole (dragging the cell wall in‚ too) in the process of plasmolysis-and the entire potatoes piece shrink‚ becoming soft and flaccid; as it was osmosis & the fluid in the vacuole that helped it keep its turgid shape and feel of density and stiffness in the first place (Bradley‚ O.‚ 2006).
