Photosynthesis is a process that occurs in plants and algae where there is a change in the energy of the incident light energy into chemical energy for living things need itself.On blue gangng Cyanophyta and bacterial photosynthesis takes place by using chemical energy and utilize nutrients, Carbondioksida, water, and using sunlight tax and release oxygen as a result.
Although photosynthesis can take place in a variety of ways in a variety of species, some characteristics are always the same. For example, the process begins with light energy absorbed by chlorophyll proteins called photosynthetic reaction centers.
Chlorophyll tax is stored in the chloroplasts. In plants, these proteins are stored in organelles called chloroplasts, while in bacteria, these proteins tax are stored in the plasma membrane. Most of the light energy gathered by chlorophylls is stored in the form of adenosine triphosphate (ATP). The rest of the energy is used to separate electrons from a substance such as water. These electrons are used in the reaction that converts karbondioksia tax into organic compounds. In plants, algae, and cyanobacteria, tax this is done in a series of reactions
The process of photosynthesis can not take place in every cell, but only in cells that contain photosynthetic pigments. tax Cells that do not have photosynthetic pigments is not able to perform photosynthesis. In January Ingenhousz experiment, it is known that light intensity affects the rate of photosynthesis in plants. This can occur because of differences tax in the energy produced by each of the light spectrum. [14] In addition to the difference in the energy, another factor that made the difference is the ability of leaves to absorb a variety of different light spectra such. [14] The differences in the leaf's ability to absorb a wide range of the light spectrum due to different types of pigments contained in the leaf tissue. [14]
Of all the solar radiation that is emitted, only certain wavelengths are used plants for photosynthesis, ie wavelengths in the range of visible light (380-700 tax nm). [18] Visible light consists of red light (610-700 nm), yellow tax green (510-600 nm), blue (410-500 nm), and violet (<400 nm). [19] Each of these different kinds of light effects on photosynthesis. This is related to the nature of the pigments that capture light in photosynthesis works. Pigment contained in grana membrane absorbs light having a certain wavelength. Different pigments tax absorb tax light at different wavelengths. Chloroplasts contain several pigments. For example, chlorophyll a absorbs mainly blue-violet light and red, while chlorophyll b absorbs blue light and reflective orange and yellow-green. Chlorophyll a direct role in the light reactions, whereas tax chlorophyll b is not directly participate in the reaction teran g. The process of absorption of light energy causes the release tax of high-energy electrons from chlorophyll a, which will then be distributed and captured by an electron acceptor. tax This process is the beginning of a long series of reactions of photosynthesis.
Chloroplasts found in all green plant parts, including stems and immature fruit. In the chloroplasts are chlorophyll pigments that play a role in the process of photosynthesis. Chloroplasts have a shape like a disc with a space called the stroma Stroma is wrapped by two layers of membrane. Thylakoid membrane is called the stroma, in which there are spaces between the membranes is called lokuli. In the stroma lamella-lamella are also piles forming grana (granum collection). Granum itself consists of the thylakoid membrane is the site of the light reactions and thylakoid space which is the space between the membrane tax thylakoid granum When a slashed then we will see some of the components such as proteins, chlorophyll a, chlorophyll b, karetonoid, and lipids. Overall, the stroma contains tax proteins, enzymes, DNA, RNA, sugar phosphates, ribosomes, vitamins, and also metal ions such as manganese (Mn), iron (Fe), and copper (Cu) photosynthetic pigments present in the thylakoid membrane Meanwhile, the conversion of light energy into chemical energy takes place in the thylakoid with the final product in the form of glucose which is formed in a strom Chlorophyll itself is only part of the device in photosynthesis known as photosystem.
Although all cells in the green parts of the plant have chloroplasts, most of the energy is absorbed in the leaves. Cells in the leaf tissue, called the mesophyll, can contain between 450,000 to 800,000 chloroplasts in each square millimeter on the leaves. Leaf surface is covered by a cuticle lil sergam
