disks was used during cellular respiration‚ the leaf disks might not have risen even though they did photosynthesize. I think to improve this experiment next time; we have to keep all these factors in mind‚ also make sure to pick the leaves off the spinach plant ourselves‚ or at least ascertain the health and age of both the leaves we use and the plant they are from‚ not to mentioned doing the vacuuming process as well. In general‚ for future experiments‚ I would allot more time and have more materials

spectrum that allows them to process a different wavelength of light for photosynthesis (Wiles‚ 2013). In this experiment we tested varying wavelengths of light to see which would cause photosynthesis to occur to the greatest degree in spinach leaf disks. The spinach leaves were hole-punched to form 60 disks. These disks were placed in a solution of sodium bicarbonate and dish detergent to create a vacuum and remove all of the oxygen from their environment. This vacuum caused the disks to sink‚ and

Column and Thin Layer Chromatography Beverly Abstract: Plant pigments were separated and concentrated from a crude spinach extract through the use of column chromatography and an eluatropic series of hexanes‚ hexane/acetone‚ and methanol. The pigments were analyzed using thin layer chromatography with a 30% ethyl acetate/hexane developing solvent. Introduction: Chromatography is a technique used to separate a mixture of two or more components based on

Many nutrients‚ including the ones that fight against cancer and heart disease are found in fruits and vegetables. 4. Vegetables have less sugars than fruits. Spinach 5. Spinach is an excellent example of a nutrient-dense vegetable. Spinach provides at least 50 % of the RDI for vitamin A‚ and about 20% of the RDI for vitamin C. Spinach is a good source of iron‚ calcium‚ and folate. Asparagus 6. Asparagus is high in folate content (20 to 50% of the RDI per serving). Folate is a nutrient identified

compound. Thin layer chromatography can be used as a physical method to segregate compounds from natural sources. E.g. Spinach leaves are visibly green‚ but consist of a variety of components that have more colour than others. This experimental procedure uses compounds from spinach leaves that are exposed to chromatography‚ TLC plate to indicate the different pigments within the spinach extract. ‘Column chromatography in chemistry is a method used to purify individual chemical compounds from mixtures
