light on the rate of photosynthesis was investigated in this experiment. The results from Figure 13 suggest that white light‚ containing all wavelengths of coloured light‚ has the highest rate of photosynthesis. Purple light had the second highest efficiency‚ followed by blue‚ red‚ and yellow light. Green light was significantly less efficient‚ producing the second lowest pH reading (Figure 14). The samples exposed to no light had the lowest rate of photosynthesis. The hypothesis that white light would

step 2: The hypothesis Answer the following questions: * What is a hypothesis? * How is a hypothesis different from a theory in science? * Describe an example of how you may use the scientific method in your daily life and state a good hypothesis for that example. * Which hypothesis did you first pick in the "Recognizing a good hypothesis" activity in the scientific method tutorial? Why? If any‚ which mistake(s) did you make when picking a hypothesis? A hypothesis is a specific

Endosymbiont Hypothesis or Endosymbiont Theory‚ as it is sometimes called (both terms are used throughout). In this essay we shall look at the history of the theory‚ how it was formed‚ who the most influential collaborators were‚ and how it is applied to the evolution of certain organelles‚ in particular‚ the chloroplast and mitochondria. The development of the Endosymbiont Theory occurred over a

needed for photosynthesis. The process of photosynthesis occurs in all plants‚ plants absorb sunlight through the leaves using the chlorophyll pigments in the leaf cells. The carbon dioxide diffuses through the stomata‚ under the leaf. The roots of the plants absorb the water from the soil and then the xylem will transport the water and nutrients upward to the leaves. As well as that the roots also store nutrients and anchor the plant. Plants also need Nitrogen to allow them to photosynthesis. Plants

photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is created as a result of the photosynthesis reaction. Since

affect Photosynthesis? Introduction: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. It produces sugar and other organic compounds such as lipids and proteins. The sugars are then used to provide energy for the organism. Light reaction is the series of biochemical reactions in photosynthesis that

The purpose of the experiment is to determine the effects of sugar on photosynthesis in Elodea. Sugar water with Elodea‚ water with Elodea‚ and water (control) are used to test for photosynthesis. Five drops of sugar water were added to sugar water with Elodea beaker. The three beakers were left under normal light for photosynthesis to occur. After 60 minutes‚ NaOH solution was added to each beaker to test the volume of CO2. The result shows that both Sugar water with Elodea and water with Elodea

explain to you why photosynthesis is bad while helping Earth too. I will be giving you a few reasons to explain that photosynthesis is important. So even though photosynthesis can kill the plant‚ photosynthesis is important‚ because it helps grow food for omnivores and herbivores. Photosynthesis grows plants and trees‚ which produce clean‚ fresh oxygen. Photosynthesis helps us living organisms with lungs breathe. It helps us when plants go through the process called photosynthesis. During this process

Introduction: Photosynthesis is a process to which some autotrophs such as plants produce their own food. It has two stages or reactions light-dependent and light-dependent reactions. The light dependent reactions are the first stage‚ where energy from sunlight is captures in Photosystem 2 and then 1‚ the electrons generated in Photosystem 1 then moves along the electron transport chain. The moving of electrons causes a hydrogen ion gradient that is used in the final step to produce ATP‚ by the
