Biology 111 Article Review 1 Sea Slug Steals Photosynthesis Genes From Algae. Janet Fang in IFL Science; February 2015 Richard Johnson Friday, February 25, 2015 Instructor: Professor Seth Kraner The first multicellular animal that is now able to produce Chlorophyll and undergo photosynthesis is a slug! The slug’s actual name is Elysia chlorotica this slug is only found deep in the deep salt waters of New England and Canada. The article talks about various ways the slug is able to eat and survive

Cell Processes: Photosynthesis Part 1: Pigments in Plant Leaves Purpose: The purpose of this experiment is to visualize the pigments present in plant leaves by using paper chromatography. Materials Used: Chromatography vial with cap, wax pencil, disposable transfer pipet, chromatography solvent, chromatography paper strip, sharp pencil, ruler, pair of scissors, piece of fresh pre-soaked spinach, coin, pair of forceps. Observations and Data: Distance of Pigments From Original Pencil Line

photosynthetic rate. Photosynthesis at low temperatures actually take CO2 more efficiently. The rate of photosynthesis is decreased by higher oxygen concentrations. Lower temperatures inhibit Rubisco and forces this enzyme to to work competitively. Rubisco works competitively because is actually binds itself to oxygen rather than binding to carbon dioxide because of the mere attraction. Therefore, in doing so, this activates photorespiration rather than photosynthesis. Photosynthesis in corn is different

MY BIOLOGY S.B.A Lab #1 Topic: Classification Aim: To classify organisms into groups Apparatus: Method: A list of 10 organisms in my school environment was made and observed. A table was constructed to show the organism and their visible characteristics. Another table was constructed to show the kingdom, phylum and class to which the organisms belong. Observation Organism | Visible Characteristics | Bird | They are vertebrates with a pair of wings. They also have a beak | Cat |

energy exserted into photosynthesis in a given time period. The background also states that during light-dependent reactions of photosynthesis, light energy is absorbed by chlorophyll molecules within the thylakoid. This indicates that since there was an increase in light energy being inserted into the chlorophyll molecules in the 15 minute time period by the 30 cm Light CO2 when compared to the 50 cm Light CO2, the electrons began to move at greater speeds throughout photosynthesis, resulting in the

NAME: Bobby Morris How do photosynthesis and cellular respiration compare? Follow the directions in the virtual lab to complete the photosynthesis and respiration puzzle. Make sure to read the virtual “book” (or use your textbook) to correctly order the processes. When complete check your results. Copy and paste your Screen Shot here. JOURNAL QUESTIONS 1. What is the importance of the light and dark reactions in photosynthesis? Light Dependent Reaction is the initial stage

1st Hour 12-4-15 Cellular Respiration and Photosynthesis In my Photosynthesis Lab my group changed the amount of light intensity by increasing the amount of Light Bulbs used (2 per cup), making it Qualitative. By increasing the amount of light bulbs we noticed that the leaf disks floated to the top of the water 2 times as fast. The leaf disks floated to the top because the water put little pockets of CO2 and Oxygen and us putting more light bulbs the Oxygen and CO2 were being ¨put into” the

Science Lab Report. Section 808 Photosynthesis. 19th of October 2012. Introduction Definition: Photosynthesis is the physico-chemical process by which plants, algae and photosynthetic bacteria use light energy to drive the synthesis of organic compounds. In plants, algae and certain types of bacteria, the photosynthetic process results in the release of molecular oxygen and the removal of carbon dioxide from the atmosphere that is used to synthesize carbohydrates (oxygenic photosynthesis) Whitmarsh
