lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration by putting the syringes in box containing no light and then waited for the spinach disks to sink. The exact process

However‚ other cultivated varieties include the leaf vegetables chardand spinach beet‚ as well as the root vegetables sugar beet‚ which is important in the production of table sugar‚ and mangelwurzel‚ which is a fodder crop. Three subspecies are typically recognised. All cultivated varieties fall into the subspecies Beta vulgaris

natural energy source for photosynthesis. White light form the sun is a mixture of all the colors of the light spectrum: red‚ orange‚ yellow‚ green‚ blue‚ and violet. Light can be either absorbed or reflected by substances called pigments. Most plants are green because the pigment chlorophyll reflects green and yellow light and absorbs the other colors of the spectrum. Problem: • Which colors of the light spectrum are most important for plant growth? Hypothesis: • I believe that if we use the colors

chloroplasts‚ the process had to have been completed rapidly in subdued light. When the solutions were not being used they were stored on ice. Ten spinach leaves were rinsed and deveined. They were then placed over ice and chopped with a razor. After‚ the spinach was placed between eight layers of cheesecloth to squeeze all the liquid derived from the spinach. The liquid was then diluted by adding 20mL of homogenizing buffer (HB). The solution was added to a pre-cooled conical centrifuge tube‚ and

By testing the effectiveness of these reactions within chloroplasts‚ the ability of spinach to thrive in varied temperatures was determined.

Paper chromatography‚ which is a useful technique for separating and identifying pigments and other molecules from cell extracts that contain a complex mixture of molecules. The solvent moves up the paper by capillary action‚ which occurs as a result of the attraction of solvent molecules to the paper and the attraction of solvent molecules to one another. As the solvent moves up the paper‚ it carries along any substances dissolved in it. The pigments are carried along at different rates because they are not e

respiration‚ photosynthesis would not be able to perform. The process of photosynthesis is able to perform its duties with the help of an organelle called chloroplast as well. Within the chloroplasts lie thylakoids‚ a membrane system that contains pigments which are used to capture light energy. Photosynthesis is also responsible for reducing carbon dioxide into glucose‚ because reducing power is present. Reducing power is made after electrons get excited in the chlorophyll molecule. To carry out

This process occurs in plants and some algae. Plants need only light energy‚ CO2‚ and H2O to make sugar. The process of photosynthesis takes place in the chloroplasts‚ specifically using chlorophyll‚ the green pigment involved in photosynthesis. ------------------------------------------------- http://biology.clc.uc.edu/courses/bio104/photosyn.htm ------------------------------------------------- 2- Chloroplasts: are organelles found in plant cells and other
