Full Answer Photosynthesis is a complex natural process that takes place when plants convert sunlight into energy. In addition to taking place in all plant species, photosynthesis is carried out by some algae and bacteria. The energy produced by photosynthesis is a type of chemical energy that is then used to fuel basic life functions such as growth and reproduction. The Process of Photosynthesis To perform photosynthesis, plants require three elements.
Back to Top Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATPthe "fuel" used by all living things.
The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll.
Most of the time, the photosynthetic process uses water and releases the oxygen that we absolutely must have to stay alive. Oh yes, we need the food as well!
We can write the overall reaction of this process as: Image from Purves et al. Leaves and Leaf Structure Back to Top Plants are the only photosynthetic organisms to have leaves and not all plants have leaves.
A leaf may be viewed as a solar collector crammed full of photosynthetic cells. The raw materials of photosynthesis, water The equation for photosynthesis carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf. Cross section of a leaf, showing the anatomical features important to the study of photosynthesis: Water enters the root and is transported up to the leaves through specialized plant cells known as xylem pronounces zigh-lem.
Land plants must guard against drying out desiccation and so have evolved specialized structures known as stomata to allow gas to enter and leave the leaf.
Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata. Unfortunately for the plant, while these gases are moving between the inside and outside of the leaf, a great deal water is also lost. Cottonwood trees, for example, will lose gallons of water per hour during hot desert days.
Carbon dioxide enters single-celled and aquatic autotrophs through no specialized structures. Pea Leaf Stoma, Vicea sp. This image is copyright Dennis Kunkel at www.
Wavelength is defined as the distance from peak to peak or trough to trough. The energy of is inversely porportional to the wavelength: Wavelength and other saspects of the wave nature of light.
The order of colors is determined by the wavelength of light. Visible light is one small part of the electromagnetic spectrum. The longer the wavelength of visible light, the more red the color. Likewise the shorter wavelengths are towards the violet side of the spectrum.
Wavelengths longer than red are referred to as infrared, while those shorter than violet are ultraviolet.
Light behaves both as a wave and a particle. Wave properties of light include the bending of the wave path when passing from one material medium into another i. The particle properties are demonstrated by the photoelectric effect.
Zinc exposed to ultraviolet light becomes positively charged because light energy forces electrons from the zinc. These electrons can create an electrical current. Sodium, potassium and selenium have critical wavelengths in the visible light range.
The critical wavelength is the maximum wavelength of light visible or invisible that creates a photoelectric effect. The color of the pigment comes from the wavelengths of light reflected in other words, those not absorbed. Chlorophyllthe green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects to be detected by our eyes.
Black pigments absorb all of the wavelengths that strike them. Pigments have their own characteristic absorption spectra, the absorption pattern of a given pigment.Photosynthesis can be represented using a chemical equation.
The formula for photosynthesis is 6CO2 + 6H2O + light energy = C6H12O6 + 6O2. In words, the equation translates to the combining of water, carbon dioxide and light energy to produce glucose and oxygen. Mar 18, · Photosynthesis | #aumsum #kids #education #science #photosynthesis - Duration: Photosynthesis song new and complete version - Duration: Peter Weatherall , views. Photosynthesis is also important in maintaining the levels of oxygen and carbon dioxide in the atmosphere. Here is the word equation for photosynthesis: carbon dioxide + water → glucose.
The overall balanced equation is 6CO 2 + 6H 2 O > C 6 H 12 O 6 + 6O 2 Sunlight energy. Where: CO 2 = carbon dioxide H 2 O = water Light energy is required C 6 H 12 O 6 = glucose O 2 = oxygen. Equation for Photosynthesis Photosynthesis equation is the simplified representation of this process in a chemical reaction format, which occurs in chloroplasts.
Read . Photosynthesis is also important in maintaining the levels of oxygen and carbon dioxide in the atmosphere.
Here is the word equation for photosynthesis: carbon dioxide + water → glucose. Photosynthesis Equation. In photosynthesis, solar energy is converted to chemical energy. The chemical energy is stored in the form of glucose (sugar).
Carbon dioxide, water, and sunlight are used to produce glucose, oxygen, and water. The chemical equation for this process is.
The chemical equation for photosynthesis involves the input (reactants) of carbon dioxide, water, and sunlight to produce the outputs (products) of glucose and oxygen. This chemical process is a fundamental equation for understanding how photosynthesis compliments respiration.
Study the general equation for photosynthesis and be able to indicate in which process each reactant is used and each product is produced. List the two major processes of photosynthesis and state what occurs in those sets of reactions.
