make it faster or slower. Therefore‚ the concept of varying wavelengths becomes obsolete when it’s dependant on several other factors. Also‚ if the concentration of NaHCO3 increased or decreased‚ it would affect the rate of photosynthesis‚ as all plants requires carbon dioxide in one form or another to

law of Thermodynamics‚ energy can never be created nor destroyed‚ but can only be transformed. Thus‚ the sun burns up its mass to release light and mass to release light and heat energy that reach the earth. It is this light energy that Chlorophyll plants‚ protists (algae) and monerans (bacteria and cyanobacteria) capture and convert to chemical energy through photosynthesis (photo-light; synthesis-building up) ‚ the key process by which energy that ultimately comes from sunlight is supplied to nearly

it appears green. The leaves and the stem reflect a green light as they also absorb multiple colors. Molecules that absorb colors are usually called pigments. As humans and animals have pigments in the skin plants have a different kind of pigment. The most common pigment they have is chlorophyll which happens to absorb the red and green light. Plants also absorb the light as they use it for energy to turn carbon dioxide into proteins‚ and carbohydrates. A rainbow is a

Hypothesis The lack of chlorophyll in kidney beans is due to the environment. Presence of chlorophyll in plants Chlorophyll is a green pigment found in the cyanobacteria and the chloroplasts of algae and plants. Chlorophyll is an extremely important biomolecule critical in photosynthesis‚ allowing plants to absorb energy from lights. Chlorophyll is present in specialised cells within plants and many algae‚ when sunlight is present‚ chlorophyll combines it with water and carbon dioxide and creates

Light on Plant Growth Introduction: Photosynthesis is the process in which plants use light energy‚ water‚ and carbon dioxide to produce food. Plants use the food they make for the growth and for the carrying out other life processes. Sunlight is the natural energy source for photosynthesis. White light form the sun is a mixture of all the colors of the light spectrum: red‚ orange‚ yellow‚ green‚ blue‚ and violet. Light can be either absorbed or reflected by substances called pigments. Most plants

Distinguish between the strategies used by autotrophs and heterotrophs to obtain free energy for cellular processes. In other words‚ how and in what form does each capture and store that energy? 2. Explain how photosynthesis differs in eukaryotic organisms (with organelles such as chloroplasts) and in prokaryotic organisms (single-celled‚ no organelles). 3. How does a metabolic

found in plant cells. Chloroplasts contain small pigments called chlorophylls. Animal cells do not have chloroplasts. All green plants you see are working to convert the energy of the sun into sugars. Plants are the basis of all life on Earth. They create sugars‚ and the oxygen that we breathe. This process is also known as chloroplast. The mitochondria work in the opposite direction and breaks down the sugars and nutrients that the cell receives. Photosynthesis is the process of a plant taking energy
