Carbon Dioxide Greenhouse Gases
827 wordsCarbon dioxide is a gas comprising less than 0. 04 % of the atmosphere. It is used by plants to make, directly or indirectly, all of the food that we eat. Increases in the concentration of carbon dioxide generally increase the growth rate of plants and decrease their water use. The concentration of carbon dioxide in the atmosphere is increasing, mostly as a result of burning of coal, oil, gas and forests. Its concentration may double by the end of the next century. Carbon dioxide also significan...

Carbon Dioxide Hydrogen Ions
1,424 wordsPhotosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. Photosynthesis powers almost all trophic chains and food webs on the Earth. The net process of photosynthesis is described by the following equation: 6 CO 2 + 6 H 2 O + Light Energy = C 6 H 12 O 6 + 6 O 2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunli...

Pigment Molecules Calvin Cycle Light
216 wordsPhotosystem 1 &# 03 Photosynthesis occurs in 3 main stages: energy is captured from sunlight, then it? s converted into chemical energy and stored in organic molecules. Photosystem's are light harvesting units of the thylakoid membrane. Each photosystem has four hundred pigment molecules. A photon hits the pigment molecules and travels through each molecule and then reaches the reaction center as shown in figure 1 - 1. The thylakoid membrane has two photosystem's, photosystem 1 &# 038; 2. The re...

H 2 O Carbon Dioxide
854 wordsColours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1. 1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in ...

Genetically Engineered Calvin Cycle
827 wordsC 3 and C 4 plants have two things in common, they both are found in hot and very dry areas and they both use photo respiration. However, the difference is the way they react toward water loss which will affect photosynthesis. If a C 3 plant starts to transpire rapidly because it is photosynthesizing and the stomata are open, then it will close the stomata, ending photosynthesis. What the plant does next is undergo a counterproductive cycle called photo respiration. In the C 3 plant photo respir...
