Bella Nelson 11/25/12 Regents Biology 3BCD Osmosis and Plasmolysis Problem: What is the effect of Osmosis on a chicken egg? What is the effect of different solutions with various concentrations on plant cells? Hypothesis: 1. In an animal cell in a hypertonic solution the egg will swell‚ in a hypotonic solution the egg will swell. 2. In a plant cell in a hypertonic solution it will shrink‚ and in a hypotonic solution

* Question 1 5 out of 5 points | | | The secretaries have asked us to provide a lounge area where they can spend their coffee breaks.This request will have to be refused.If we give them lounge areas‚ next they will be asking for spas and swimming pools. Then it will be racquetball courts‚ tennis courts‚ and fitness centers.Expenditures for these facilities for the secretaries will drive the company into bankruptcy.Answer | | | | | Selected Answer: | Slippery slope | | | |

concentration of free energy. (http://en.wikipedia.org/wiki/Osmosis) Plasmolysis plays an important role in Osmosis. It is the process in plant cells in which the cytoplasm is extracted away from the cell wall due to the loss of water via osmosis. This process occurs in a hypertonic solution. When a plant cell is in a hypertonic solution‚ the water in the cells move to a region of higher solute concentration. (http://en.wikipedia.org/wiki/Plasmolysis) This results to the cell shrinking and in doing so; it becomes

Akapulko Ringworm Bush Family: Fabaceae Scientific Name: Cassia alata L. Plant Description: Akapulko is a coarse‚ erect‚ branched shrub‚ 1.5 to 3 meters high. Leaves are pinnate and 40 to 60 centimeters long‚ with orange rachis on stout branches. Each leaf has 16 to 28 leaflets‚ 5 to 15 centimeters in length‚ broad and rounded at the apex‚ with a small point at the tip. Leaflets gradually increase in size from the base towards the tip of the leaf. Inflorescences are terminal and at the

Abstract: As can be observed‚ the uses of the pandan tree are not limited to cooking uses. Its leaves and roots are found to have medicinal benefits. Such parts of the plant have been found to have essential oils‚ tannin‚ alkaloids and glycosides‚ which are the reasons for the effective treatment of various health concerns. It functions as a pain reliever‚ mostly for headaches and pain caused by arthritis‚ and even hangover. It can also be used as antiseptic and anti-bacterial‚ which makes it

called cytolysis that occurs when a cell burst due to an osmotic imbalance that has caused excess of water to move into the cell. When hypertonic happens is when the water of the cells passes trough osmosis into the environment and this is when plasmolysis happen that is the process in which cells lose water so the cell shrinks. AIM: To investigate the osmolarity
