AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

Aquaponics system is a food production system that combines conventional aquaculture‚ raising aquatic animals such as snails‚ fish‚ crayfish or prawns in tanks‚ with hydroponics cultivating plants in water in a symbiotic environment. In normal aquaculture‚ excretions from the animals being raised can accumulate in the water‚ increasing toxicity. In an aquaponic system‚ water from an aquaculture system is fed to a hydroponic system where the by-products are broken down by nitrogen-fixing bacteria

“Respiration” and “Photosynthesis” All life depends on two chemical reactions “Respiration” and “Photosynthesis”. These two processes are quite crucial because they are a source to nearly all life on Earth. Both of these processes are quite similar yet differentiate vastly. In this essay I’ll be comparing and contrasting “Photosynthesis” and “Respiration”. I’ll start by discussing what actually happens

The effect of different wavelengths of light on photosynthesis rate in spinach leaves Abstract: This experiment was performed to test the effect of different wavelengths of light had on photosynthesis. According to the results gathered we can say that if two plants are put under different lights‚ one green and one a normal light‚ that the plant under the normal light will perform photosynthesis at a higher rate than the plant under the green light. This experiment is important because it shows

Chloroplasts and Photosynthesis All animals and most microorganisms rely on the continual uptake of large amounts of organic compounds from their environment. These compounds are used to provide both the carbon skeletons for biosynthesis and the metabolic energy that drives cellular processes. It is believed that the first organisms on the primitive Earth had access to an abundance of the organic compounds produced by geochemical processes‚ but that most of these original compounds were used up billions
