Put simply‚ photosynthesis is the process of converting light energy into chemical energy and storing it in the bonds of sugar. Photosynthesis comes from the Greek language and literally means “Light Composition” or “Putting Together Light.” Photosynthesis generally takes place in plants‚ however it also takes place in algae and many species of bacteria. In photosynthesis‚ light energy is converted to chemical energy and the chemical energy is then stored in the form of glucose‚ or sugar. Carbon

possible by my AP Biology teacher’s assignment. If not for her‚ I would never have sat down and composed a four page script about Photosynthesis. I would also like to thank my supporting family for listening to my complaints and frustrations throughout this process. My gratitude goes out to the AP Bio Facebook group as well‚ for answering all the questions I had about Photosynthesis. Thank you all very much.

“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

HW Review for Photosynthesis exam: Due Monday March 28 Reminder your lab write up will be a next week. If your lab is this Friday you also will get a week to complete your full lab write-up. Sample questions: 1. twenty-five plants were placed in each of four closed containers and then exposed to light conditions shown in the data table below. All other environmental conditions were held constant for a period of 2 days. At the beginning of the investigation‚ the quantity of CO2 present in each closed

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

Factors Affecting Photosynthesis Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However‚ after reaching an intensity of 10‚000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may‚ in fact‚ slow down the rate as it bleaches the chlorophyll. Normal sunlight (usually with an intensity of about 100‚000 lux) is quite sufficient for a normal rate of photosynthesis. Open and Closed

The effect of wavelength of 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

Photosynthesis is process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing‚ photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen‚ on which most organisms depend. Photosynthesis occurs in green plants‚ seaweeds‚ algae‚ and certain bacteria. These organisms are veritable sugar factories‚ producing millions of

Investigating Functionalism Functionalism is a theory about the nature of mental states. According to functionalism‚ mental states are functional states that are defined by their functional roles (causal relations to other things) rather than their intrinsic qualities. To illustrate the difference between the two ways of defining something‚ entities such as clocks (to display time) and calculators (to manipulate numbers) are defined functionally‚ whereas entities such as water (H2O) and gold (Au)

Investigating the ‘Belief Bias’ Effect in Human Reasoning Abstract In this report an experiment was conducted to investigate the belief bias effect in human reason‚ the weighting attached to logic and belief in syllogistic reasoning. Belief biases were observed despite controls for conversion of premises. Belief bias was shown to be more marked in the invalid than the valid syllogisms. This consistent interaction between belief and logic was also noted. However‚ participants were intermediate
