Chloroplasts And Solar Energy

Chloroplast: An organelle bounded by a double membrane containing the enzymes and pigments that perform

If plants didn’t have chloroplast, life as we know it would not be here. We would all die because we could not get energy from the sun. We get our energy from the sun by either from eating plants or eating animals that eat the plants that get there energy from the sun. The chloroplasts are responsible for harvesting and turning sunlight into energy. Another reason we would all be dead is because plants give us oxygen and if we did not have oxygen we could all get carbon dioxide poisoning.

The school and cells also both have “chloroplasts.” The function of chloroplasts is to create energy from sunlight. Similarly, the school has several solar panels. They absorb sunlight and turns it into usable electricity.

Chloroplasts are important photosynthetic organelles that present in plant cells. It is believed that chloroplasts evolve from an endosymbiotic event; engulfment of a photosynthetic cyanobacterium by a large heterotrophic host cell (1, 2). During this process proteins in the cyanobacterium has been transferred to the nucleus and also the proteins that are essential for organelle biogenesis has been transferred to the cyanobacterium making it dependent on the host. Although chloroplast proteins have estimated to consist of 3500-4000 different types of polypeptides, the protein coding capacity in chloroplast genes is approximately 200 polypeptides (3, 4). This data further suggest that most of the proteins found in chloroplast are encode by nuclear genome and transport to the chloroplast. At least, a few proteins are use secretory pathway in which first targeted to the endoplasmic reticulum and then transfer to the chloroplast through vesicles (5-7).

Chlorophyll- a green pigment, present in all green plants responsible for the absorption of light to provide energy for photosynthesis.

This is known as the light dependent reaction of photosynthesis. The goal of photophosphorylation is to take the energy from sunlight and convert it into chemical energy for the Calvin cycle. The Calvin cycle then takes this chemical energy and uses it to make glucose. Photophosphorylation begins when a photon (packet of light) is absorbed by a pigment (light absorbing molecule), which is attached to a protein along the thylakoid membrane of the chloroplast. The energy from the photon creates resonance (electron passing from one pigment to the next), which eventually reaches a special reaction center. The reactions center is a protein that houses a special pair of chlorophyll molecules capable of releasing electrons. When the chlorophyll molecules get excited, they release two electrons. These two electrons then move along the membrane through a series of specialized protein releasing energy as they go. This action creates an H+ gradient inside the lumen of the chloroplast. Eventually the electrons reach the end of the chain and attach onto electron carriers. The H+ flow across the ATP Synthase protein where they meet up with ADP (andesine diphosphate) and Pi (phosphate group) to from ATP. The chemical energy created can then be used in the Calvin

The chloroplasts are organelles found in plant cells. The chloroplast is the site of photosynthesis. Since chloroplast is the site of photosynthesis it is also where sugar is produced, because glucose is a product of photosynthesis. To begin with, I made a solar power sugarcane processing plant. The reason being is that the chloroplast is where photosynthesis takes place and a product of photosynthesis is glucose (sugar), and a sugarcane processing plant produces sugar. In photosynthesis, light energy from the sun is converted into chemical energy, which is then stored and also used to make glucose. I have a light in the corner to represent the sun and solar panels on the roof, which shows energy transformation.

Photosynthesis is the process that plants use to convert light energy into chemical energy. The chemical energy is stored in glucose. The chemical reaction for photosynthesis is: 6CO2 + 6H2O (+ light energy) → C6H12O6 + 6O2. Glucose needs UV light, carbon dioxide, and water to form. The UV light from and water is absorbed into the plant by the leaves of the plant. In the mesophyll cells of the leaves, organelles called the chloroplasts contain chlorophyll that absorbs the energy from light (Campbell and Lawrence, 1999). Chlorophyll looks green because it absorbs red and blue light; it is the green light which

Plants utilize chloroplasts to perform photosynthesis to produce glucose. Photosynthesis consists of two stages called light reactions and the Calvin cycle. Within the chloroplast, the thylakoid is the site of light reactions. The thylakoid is capable of absorbing light energy and transforming it to chemical energy in the form of ATP and NADPH which will later be used in the Calvin cycle. Pigments located inside the thylakoid allows for the absorption of visible light (Campbell, pg. 191). There are three significant types of pigments in chloroplast: chlorophyll a (main light-absorbing pigment) , chlorophyll b (accessory pigment), and carotenoids (group of accessory pigments).

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorbs sunlight and use it in conjunction with water and carbon dioxide to produce sugars. Chloroplasts have similar jobs like the windows at the Westminster Mall. It provides sunlight and photosynthesis for the people that are inside like organelles that are inside of a

Both chloroplasts and mitochondria contain circular DNA knowns as chloroplast DNA and mitochondrial DNA respectively, signifying that both organelles have prokaryotic origins. The presence of mitochondria in eukaryotes allows for ATP synthesis through the electron transport chain and oxidative phosphorylation (Chinney et al, 2003), thus enabling eukaryotes to satisfy their high metabolic requirements, particularly in animals. The production of large amounts of ATP energy allows for the sustenance of life in a wide variety of environmental conditions as they are able to produce the energy required. The unique double membrane of the mitochondria suggest that it was formed as a result of primary symbiosis, and are homologous to plastids. Similarly chloroplasts enable eukaryotes to take advantage of sunlight as a natural resource, which allows the process of photosynthesis, where the reaction of carbon dioxide and water is converted to glucose and oxygen gas (Cogdell, 2013), using light energy produced by the sun with the aid of chlorophyll. This conversion of light energy into chemical energy forms the primary source of all energy accessible by the animal consumers on land, through the producers - the plants. At the cellular level, protists are the most simple examples of endosymbiosis. In the amoeba Paulinella chromatophora it contains two chromatophores, derived from once free living cyanobacteria (Wernegreen,

During the experiment I noticed that in the onion cell there were no chloroplasts. There were no chloroplasts in the onion cell because in an onion the cells are used for storing energy not for photosynthesis and it grows under ground so there are no leaves on the physical body of the onion so it is unable to go through photosynthesis. The stem however of the onion has leaves above the ground but they do not serve a purpose after the onion has been picked. The cells, which contain chloroplasts that are located in the stem, are discarded therefore leaving the bulbous section of the onion that contains specialized cells that contain no chloroplasts. Also in the onion cell there were only 4 visible parts: the nucleus, the vacuole, the cell wall and the cytoplasm.

Algae is a good example of where you can find chloroplast. When looking at chloroplast the appearance would be a green pigment known as chlorophyll. Chlorophyll absorbs light energy for production. In plant chloroplast which are commonly found in plant leaves have different structures each of them being important. The membrane envelope contains lipids for protection, and keeping chloroplast closed regulates what goes in and out of the cell.

With surely convincing evidence researchers have been able to compile in support of the endosymbiosis theory, it becomes hard for one to deny the possibility that cilia, mitochondria and chloroplasts once existed as bacterial organisms (later to be taken up by host cells by endosymbiosis).

17) They both function in order to make energy. Mitochondria make energy called ATP, for animal cells, while chloroplasts make energy called sugar, or glucose, for plant cells.
