Plant photosynthesis happens in leaves and stems with green stem with a special organelle called a chloroplast. A plant leaf has tens of thousands of cells, and they contain 40-50 chloroplasts. The chloroplast, is an oval-shaped structure, and is divided by membranes into numerous disk-shaped compartments. The disk like compartments, which are called thylakoids, are placed vertically in the chloroplast and look like a stack of plates or pancakes. One stack of thylakoids is called a granum or more than one grana, the grana lie placed in a fluid known as the stroma. Inside of the thylakoids are hundreds of molecules of chlorophyll, which is a light capturing pigment used for photosynthesis. More light trapping pigments, like enzymes used to speed up chemical reactions, as well as other molecules used for photosynthesis and in the thylakoid membrane. These pigments …show more content…
The first stage is the light dependent reaction(it was called the light reaction), and the chloroplast traps light energy and changes it into chemical energy which is (NADPH) and (ATP), these are two molecules used in the second stage of photosynthesis. In the second stage, this is called the light-independent reaction (it was called the dark reaction), NADPH gives the hydrogen atoms to help form glucose, and ATP gives the energy for reactions used to make glucose. The stages are literal meaning of photosynthesis, to build with light. In the light-dependent reaction photosynthesis depend on the energy flow started by light energy. Electrons are small particles that move in a specific orbit around the nuclei of atoms and have a small electrical charge. Light energy causes the electrons in chlorophyll and other light-trapping pigments to increase up and out of orbit; the electrons automatically fall back into place, releasing energy, or vibrating energy, as they go, all in millionths of a
Photosynthesis consists of the following equation: Sun light Carbon dioxide + Water = = == == ==> Glucose + Oxygen Chlorophyll Chlorophyll is a substance found in chloroplasts, found in the cells of leaves.
Both starch and sucrose can be converted back into glucose and used in respiration. Photosynthesis happens in the mesophyll cell of leaves. There are two kinds of mesophyll cells - palisade mesophyll and spongy mesophyll. The mesophyll cells contain tiny bodies called chloroplasts which contain a green chemical called chlorophyll.
Experiment #1: The purpose of this experiment is to investigate the effects of baking soda and light intensity on the rate of photosynthesis of green spinach leave through the observation of floating disk.
The Effect of Light Intensity on the Rate of Oxygen Production in a Plant While Photosynthesis is Taking Place
Photosynthesis can occur in any green part of the plant. This green part contains chloroplasts. Chloroplasts separate photosynthesis and other cellular activities. The cytoplasm like liquid, stroma, in chloroplast consists of ribosome, DNA, and enzymes which takes part in photosynthesis. There are two stages in photosynthesis: light dependent and light independent. In light dependent stage, by using light energy water is broken into hydrogen and oxygen. In light independent stage, hydrogen reacts with CO₂. Also, water is reformed. This stage both happens when it is dark or light.
An Analysis and Evaluation of Data from Photosynthesis Experiments Graph analysis This is my analysis for the investigation in to the affect of light intensity on the rate of photosynthesis to the Canadian pondweed, elodea. In the results the pattern is that when the light intensity is higher the readings are generally higher. On the graph the less the light intensity the lower the gradient of the curve. the equation for the photosynthesis process is; CO2 + 2H2O + Light Energy = =
The process of photosynthesis is present in both prokaryotic and eukaryotic cells and is the process in which cells transform energy in the form of light from the sun into chemical energy in the form of organic compounds and gaseous oxygen (See Equation Below). In photosynthesis, water is oxidized to gaseous oxygen and carbon dioxide is reduced to glucose. Furthermore, photosynthesis is an anabolic process, or in other words is a metabolism that is associated with the construction of large molecules such as glucose. The process of photosynthesis occurs in two steps: light reactions and the Calvin cycle. The light reactions of photosynthesis take place in the thylakoid membrane and use the energy from the sun to produce ATP and NADPH2. The Calvin cycle takes place in the stroma of the chloroplast and consumes ATP and NADPH2 to reduce carbon dioxide to a sugar.
product and glucose levels. Plants trap the energy in sunlight using chlorophyll, a light trapping pigment found in leaf plant cells. It then uses carbon dioxide which enters the plant through small holes found. on the underside of the leaf called stoma and water which enters the
Short version: Photosystem II is one of two light-capturing units in a chloroplast 's thylakoid membrane. Photosystem I absorbs photons of wavelength of 680 nm. Light energy is captured by chlorophyll and transferred into high energy electrons; Water is broken up into Oxygen and Hydrogen Ions and Electrons; Electrons are sent to electron transport chain.

Chlorophyll in the cells in the palisade layer absorb light for photosynthesis. The plant releases the oxygen created in photosynthesis back into the air but it uses or stores the glucose for energy, respiration, growth and repair. The leaves and plants are also specially adapted for photosynthesis in their structure and cell alignment.

What is Photosynthesis exactly? Well the simplified version that we’ve all been told when we’re young is that it is something that plants do that changes carbon dioxide into oxygen so we can breath. While partially true there is still so much that is missing. Photosynthesis is the process of plants absorbing light energy from the sun into those chloroplasts and converting it into chemical energy, or sugar. Plants use the energy from the sunlight they absorb to convert the carbon dioxide from the air and water from the soil into glucose (sugar) and H2O (oxygen). Most of the cool stuff with the chloroplasts happens mainly in the leaves of plants. Simply put the carbon dioxide that the plants need for the chemical reaction are absorbed by stomata in the
This organelle is the site of photosynthesis in plants and other organisms. In the structure, the chloroplasts has a double membrane, the outer membrane has a continuous boundary. This organelle can be found in a vast group of organelles called the plastid, chloroplasts are usually found in many plant cells but never in animal cells. Chloroplasts organelles are large; they are 4-10um long and 2-3um wide. They are very important to plants because chloroplasts are what plants use to create food from sunlight. Chloroplasts are not found in humans.
Photosynthesis is a process in which plants and other organisms convert the light energy from the sun or any other source into chemical energy that can be released to fuel an organism’s activities. During this reaction, carbon dioxide and water are converted into glucose and oxygen. This process takes place in leaf cells which contain chloroplasts and the reaction requires light energy from the sun, which is absorbed by a green substance called chlorophyll. The plants absorb the water through their roots from the earth and carbon dioxide through their leaves.
In some way, shape, or form energy is one of the several reasons why there is an existence of life on earth. Cellular respiration and Photosynthesis form a cycle of that energy and matter to support the daily functions that allow organisms to live. Photosynthesis is often seen to be one of the most important life processes on Earth. Photosynthesis is a process by which plants use the energy of sunlight to convert carbon dioxide and water into glucose so other organisms can use it as food and energy. It changes light energy into chemical energy and releases oxygen. This way organisms can stay alive and have the energy to function. Chlorophyll is an organelle generally found in plants, it generates oxygen as a result too. As you can see without
An Experiment to Investigate the Effect of Light Intensity on the Rate of Photosynthesis. Introduction Photosynthetics take place in the chloroplasts of green plant cells. It can produce simple sugars using carbon dioxide and water causing the release of sugar and oxygen. The chemical equation of photosynthesis is: [ IMAGE ] 6CO 2 + 6H20 C 6 H12 O 6 + 6O2 It has been proven many times that plants need light to be able to photosynthesize, so you can say that without light the plant would neither photosynthesize nor survive.
