Biology Standard Level : Photosynthesis

Photosynthesis occurs each time the sun’s light reaches the lives of a plant. The chemical ingrediants for photosynthesis are carbon dioxide (CO2), a gas that passes from the air into a plant via tiny pores, and water (H20), which absorbed from the soil by the plant’s roots. Inside leaf cells, tiny structures called chloroplasts use light energy to rearrange the atoms of the ingrediants to produce sugars, most importantly glucose (C6H12O6) and other organic molecules. Chlorophyll gives the plant its green color (Simon, 02/2012, pp. 92-93). Chemical reactions transfers the sun’s light energy into the chemical bonds that hold energy-carrying molecules. The most common are

Photosynthesis is the process in which plants consumed inorganic materials like solar light, carbon dioxide and water and converted it to an organic molecule like sugar and an inorganic gas like oxygen. Light is one of the major elements influencing the rate of photosynthesis; direct light concentration affects the noncyclic pathway (light

Photosynthesis is the conversion of light energy from the sun into chemical energy. During this process light energy is absorbed by the chlorophyll molecule (a green pigment found in chloroplasts of plant cells) and is then used to convert carbon dioxide and water into simple sugars, glucose. The chlorophyll molecules however absorb different colours enabling plant growth as well as food production and by this it could be identified whether photosynthesis does occur or not. Blue and red light are the most absorbed and this is because they are colours that are most effective when driving photosynthesis. Green light is reflected which is why leaves appear green. Plant growth will occur the most under the red and blue light but not green. This is because red light wavelengths which are absorbed by the leaves of the plant will produce a hormone which stimulates budding and flowering of plants and blue light will promote photosynthesis which increases the rate at which it occurs.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms ' activities. Plants need photosynthesis to survive. The balanced chemical equation for photosynthesis is 6 CO2 + 6 H2O ? C6H12O6 + 6 O2. In English terms, this equation translates to six carbon dioxide plus six

All plants photosynthesize to produce glucose, which is stored chemical energy as the plants food can be converted into energy through respiration for life processes. The rate of photosynthesis has three main limiting factors – carbon dioxide concentration, light intensity

During photosynthesis, the section that is light dependent stage is in the thylakoids in the Mitochondria of a plant cell, while the light independent stage is in the stroma of the Mitochondria of a plant cell, specifically named the Calvin cycle. The light dependent and light independent stage work together to perform photosynthesis. The light independent gives ATP and NADPH to the light independent stage. In return, the light independent stage gives the light dependent stage NADP+ and ADP. The light dependent stage works in the thylakoids of the Mitochondria in a plant cell. It starts off by light energy being absorbed by photosystem II,

Photosynthesis is essential to all living organism such as animals and plants. Photosynthesis is a process used by plants and other autotrophs to capture light energy and use it to power chemical reaction that converts carbon dioxide and water into oxygen, carbohydrates and water. (Textbook: Principles of Biology). The reactants and the products of photosynthesis are:

Photosynthesis is a process used by plants, algae and certain bacteria to harness energy from sunlight into chemical energy.

The Effect of Light Intensity and Temperature on the Rate of Photosynthesis Aim The aim of my experiment is to determine whether intensity of light and temperature would affect the rate of photosynthesis in a plant. To do this, I will place a piece of pondweed in varying light intensities and temperatures, and observe the amount of oxygen being given off. I am using pondweed because of its unusual quality of giving off bubbles of gas from a cut end, when placed in water. Introduction Photosynthesis occurs only in the presence of light, and takes place in the chloroplasts of green plant cells.

Photosynthesis is the conversion of light energy to chemical energy. There are many different factors that can affect the rate of photosynthesis, those being light intensity, the temperature of the water, the amount of carbon dioxide in the water, and the color of the light. In this experiment we chose to alter the color of light that was used in the process involving the aquatic plant Elodea while maintaining the other 3 factors. This experiment was conducted to see how much of an effect the color of the light played in the amount of carbon dioxide produced in the process of photosynthesis. We measured the amount of NaOH that was needed to color the water pink and then converted the net difference of drops into the net volume of carbon dioxide that was produced or consumed. The results showed that there was not a significant difference in the amount of carbon dioxide produced when using a standard regular colored light bulb compared to a green light bulb.

Water combines with carbon dioxide in the presence of sunlight within the chlorophyll of leaves to manufacture food (glucose) and oxygen is liberated as a by-product. Photosynthesis occurs in all green plants. Photosynthesis is an endothermic reaction and it consists of a series of complex reactions. This reaction during photosynthesis is grouped into two stages called Light reaction and Dark reaction. During this process, oxygen is given

Photosynthesis is a process in plants, algae, and some prokaryotes, that coverts solar insulation into chemical energy stored in glucose or other organic compounds. Photosynthesis occurs in slightly different ways in higher plants relative to photosynthetic bacteria. Photosynthesis is an important process because it harnesses the sun's energy into utilizable forms of energy on earth. Most biological organisms such as animals and fungi are unable to directly use light energy to power biological processes such as active transport, cell division and muscle movement. ATP is used to power these processes. Photosynthesis converts light energy into chemical energy in the form of glucose and then the process of cellular respiration converts energy in glucose to energy in the form of ATP which is ultimately used to power biological processes. The energy produced by photosynthesis forms the foundation of virtually all terrestrial and aquatic food chains. As a result, photosynthesis is the crucial source of carbon in the organic molecules found in most organisms. The high oxygen concentration in the atmosphere is derived directly from the light reactions of photosynthesis. Prior to the evolution of photosynthesis on earth, the atmosphere was absent of any oxygen

Introduction: Photosynthesis occurs in the plants chloroplasts the process has two stages where a light reaction occurs also the Calvin cycle. The light reaction products are ATP, NADPH, and oxygen. The light reactions take place in the thylakoid membranes where the stages of photosystems I and II. The Calvin cycle has six steps and it takes place in the stroma. The Calvin cycle is the second step of photosynthesis and creates glucose as the final step to photosynthesis. The steps of which the Calvin cycle take place is processing a three 5-carbon compound called RuBP combines with three CO2 molecules which become three 6-carbon molecules. The second step of the Calvin cycle takes the three 6-carbon molecules which are unstable, and change into six 3- carbon molecules which are called 3- PGA. Halfway through the process of creating glucose ATP and NADPH from the light reactions provide energy and electrons to convert 3-PGA molecules into six G3P molecules. One G3P molecule exits the cycle and the remaining which is used for glucose later on. Five G3P molecules shuffle back into RuBP, getting

First let us comprehend the cycle of photosynthesis. Photosynthesis is defined as the procedure whereby light energy is transformed to chemical energy to create sugars. By breaking down the meaning one can simply say photo-means light and synthesis means to use that light to create sugar. Water is added to light in order to provide electrons and carbon dioxide is include to provide fixed carbon. Sugar is not the only output. There is a byproduct created called molecular oxygen. This is an important result because we humans and other living organisms wouldn’t be able to breathe without its existence. Photosynthesis is placed into two categories:

Photosynthesis entails a process that involves complex and fundamental actions that occur in plants, algae as well as some bacteria. They use sunlight to produce carbohydrates. Oxygen is then created from carbon dioxide (CO2) and water (Jackson, 2008). The carbohydrates created through photosynthesis enables growth and normal functioning for the plant to sustain life. Here is an example of a formulation of photosynthesis by Campbell et al.
