Light has a wave nature and particle nature. The smallest parts or units of light are called photons and the amount of photons absorbed per unit time determines the brightness of light. Wavelengths are a certain amount of energy each photon possesses as they vibrate. Chlorophyll reflects the wavelengths green part of the light spectrum because it is green and the plants that contain chlorophyll are green as well.
This article may not be reliable because there was no date or author noted. This article clearly examines in what form light is absorbed and the process thereof.
Article 2:
Photosynthesis converts light/radiant energy to chemical potential energy. The raw materials needed for this process to occur are light energy, water and carbon dioxide in order to make glucose. Light absorbed gives chlorophyll the green pigment as it absorbs red and blue light therefore making these two colours invisible to the human eye as the green is not absorbed. This means that the blue and red light are used for photosynthesis.
This article is reliable in that it has been recently updated on the website therefore any flaws or inaccuracies would have been corrected then as the process of photosynthesis does not evolve, but rather, the plant evolves and adapts itself for this process. This article clearly states that although not all parts of the light are used, it is still needed by the chlorophyll molecules and gives the molecules their characteristic green pigment.

Photosynthesis depends on light absorbed by the chloroplasts in the leaves. Nutrients would not be created by photosynthesis if it weren’t for the absorption of light. It is said that early aquatic bacteria photosynthesize using s protein complex in halobacteria- in their ...

... in the chloroplasts in some of their cells. Chlorophyll allows the energy in sunlight to drive chemical reactions. Chloroplasts act as energy transducers, converting light energy into chemical energy. So as the plant has more light the chlorophyll inside the chloroplasts can react faster absorbing in more light for food and energy.¡¨ So this shows my prediction was correct for in my experiment and shown in my result table and graph the more light intensity there is on a plant the higher the rate of my photosynthesis will be. My prediction is very close to what I said the results will be so my prediction was correct and has been proven to be correct in my result table, graph and now explained again in my conclusion.
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.
The energy inside molecules is called chemical energy, so light energy is converted into chemical energy by the chlorophyll. I believe that the results are reliable enough to support the hypothesis, because the graph of results proves the hypothesis because the gradient of the curve increases with the increase of the light intensity. I think that the method used is reliable enough to support the prediction. Overall, both graphs and my results support my predictions fully. My idea that the rate of photosynthesis would increase with light intensity was comprehensively backed up by my results.
Photosynthesis is something that helps the plants to grow, but it is also very beneficial to us because of the fact that we need to breathe oxygen to maintain our functions of life. Plants produce an abundant supply of energy that is stored because they are what I would like to call savers/hoarders. Plants store the extra energy that they produce into different things such as potatoes, carrots, and other different types of food that we use to maintain our cellular respiration. Without photosynthesis it would be hard for animals to find fuel for cellular respiration and there would be no life as we know it due to photosynthesis being one of the key roles in life. After learning about cellular respiration, I have found out that both plants and animals use this when creating energy.
energy as yellow would. Red will have a very high photosynthetic rate. even though it has the longest wavelength and therefore carries the least energy it will be greatly absorbed so a lot of the light energy will be used rather than reflected. Prediction graph. [ IMAGE] Photosynthetic equation =
To make the test fair I will use the same amount of water and the leaf
The substance that absorbs sunlight is chlorophyll, which is mainly contained in chloroplasts. This energy is used to convert carbon dioxide (CO2) and water into sugars. This conversion creates the waste product oxygen, which is used by humans for breathing. Without being able to photosynthesise plants will stop growing and die. In a plant growing in the dark the chlorophyll will slowly be destroyed causing them to use their food reserves.
Photosynthesis in simpler turns is the ability of a live plant to carry on its chemical process by the use of light energy. Photosynthesis can not take place when there is absolutely no light, instead it stores the light it captures during the day, and uses it when needed. Photosynthesis can take place in land plants and aquarian plants such as algae. There are many factors that influence the ability of a plant to go through photosynthesis, such as light, the color of light and amount of water and or light.
Photosynthetic pigments are essential for life because they allow photosynthesis to occur by capturing sunlight which is then used alongside carbon dioxide and water to form organic compounds such as glucose and oxygen. The pigments allow the conversion of light energy to chemical energy which other organisms can benefit from. Oxygen is utilised by other organisms in aerobic respiration. The different pigments present in the chloroplasts allow a wide variety of wavelengths of light to be absorbed for efficient photosynthesis and provide colours to the plant to attract pollinators.
Photosynthesis will occur at a faster rate when the plant is exposed to the sun, than when it is not exposed to sunlight.
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.
Photosynthesis and cellular respiration help sustain life on planet earth as both are metabolic processes in their own way. Photosynthesis is the process by which plants and other organisms use energy from the sun to form glucose from water and carbon dioxide. From there, glucose is then converted to ATP by way of cellular respiration. To convert nutrients that are biochemical energy into ATP, a process such as cellular respiration that has reactions needs to take shape in the cell of an organism, releasing waste products at the same time. For the continuous energy cycle that tolerates life on Earth as we know it Photosynthesis and Cellular respiration very essential. They have a few stages where energy and various connections occur within the eukaryotic cell. Cellular respiration takes place in the lysosome, an organelle that is found in the cytoplasm of eukaryotic cells. It uses enzymes to break down biomolecules including proteins, nucleic acids, carbohydrates, and lipids. Photosynthesis involves the chloroplasts, which contain pigments that absorb the sunlight and then transfigure them to sugars the plant can use. Those specific processes are crucial in how far and diversified evolution has
Photosynthesis is a key contributor to all living things; photosynthesis provides the oxygen, food, and nutrients that help all living things stay healthy and alive. Photosynthesis converts solar energy into the chemical energy of a carbohydrate. Photosynthetic organisms, including land plants, algae, and cyanobacteria, which are called autotroph...
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.
Photosynthesis is the process in which living cells from plants and other organisms use sunlight to produce nutrients from carbon dioxide and water, the image below “Diagram of photosynthesis 1,” helps show this process. Photosynthesise generally creates oxygen as a by-product through the use of the green pigment, chlorophyll, found in the plant that helps this reaction occur. “Photosynthesis provides us with most of the oxygen we need in order to breathe. We, in turn, exhale the carbon dioxide needed by plants,” (factmonster,2017). This is able to show us why photosynthesis is so greatly needed to occur through plants in order to give one another essentials needed for continuity of life. “Plants perform photosynthesis because it generates the food and energy they need for growth and cellular respiration,” (photosynthesieeducation, 2016).
