Before we conducted our experiment‚ the class learned about the photosynthetic process of‚ not only spinach discs‚ but plants in general.

In this lab‚ we extracted spinach pigments‚ and analyzed what colors of light these pigments absorb. By using TLC plate‚ hexane and acetone‚ I separated the pigments of spinach‚ and discovered that the main pigments were green and yellow. This works because with different polarities‚ pigments move at different rates. Hexane and acetone were also used to separate chlorophyll and carotene from spinach. Since they are polar‚ they can separate organic and inorganic things. From the experiment‚ I know

experiment to examine the phenotypic differences against each strain’s genotypes. The mutant strain (KBT-1) did not possess gas vesicles‚ which decreased its ability to float to the surface. The lack of gas vesicles in the mutant strain made the colonies a red color. The wild type strain (NRC-1) had gas vesicles and appeared a pink pigment color. Growth on the agar allowed one to examine the specific colonies. Inoculation and growth in the liquid culture were done to examine both strains of Halobacteria in

Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

Transpiration and Leaf Resistance By: Bernina Berber Introduction Transpiration is a part of the water cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on

The red light didn’t photosynthesize as well as the white light did and had low photosynthetic rates compared to some of the other visible lights. I think this may have happened because the lights have a color coating‚ so the red light wasn’t a pure red light and may have filtered out the light. In figure 2‚ white light almost doubles the results of the red light. Even in figure 3‚ the gross rate‚ the white and blue light were able to photosynthesize more than the red light. I think this
