Leo Pigao Susan Andres Edeliza Caparas Marites Sanchez Arma Cantre Aurora Lazaro Alma Castaño ABSTRACT Flavonoid pigments make plants colorful. Due to the varied colors‚ the researchers used extracts of Anthurium spathe‚ Onion skin and Rose petals as an alternative highlighter pen pigment to commercially available highlighter. The preparations of pigments were treated differently for quality sake. One was by boiling the samples in 100ml denatured alcohol for 1-2 minutes

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

Discussion Questions: 1. What happened to the onion skin after flooding it with salt solution? What could be a possible explanation to such observation? o Crenation happens (where the cytoplasmic contents of the cell pull away from the rigid cell wall) because the onion skin is exposed to a hypertonic solution (where the water solution on the cell is greater than that of the outside) and by osmosis‚ the water goes out of the cell‚ this process is called Plasmolysis. 2. What happened to

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

sucrose solution would cause “Incipient Plasmolysis”. Theory Plasmolysis is the result of a (in particular) plant cell which has lost vast amounts of water. When this happens‚ turgor pressure within the cell has decreased to the point where the cytoplasm of the cell membrane peels away from the cell wall. When this begins to happen it is called Incipient Plasmolysis and when the cytoplasm is almost completely gone it is call “full/complete” Plasmolysis. Plasmolysis is only possible if the cell is placed

Describe the effects of hypertonic‚ isotonic‚ and hypotonic solutions on Elodea leaf cells and onion scale leafs.
