Chloroplast Is The Site Of Photosynthesis

Virtual Lab #5- “Which Colors of the Light Spectrum are Most Important for Plant Growth?

People should buy fake trees instead of going to cut down a real one. Plants go through photosynthesis and give off oxygen. They also give us fruit and vegetables (food). Plants also help us making new seeds that will create new plants for the future. Real trees also go through photosynthesis and give off oxygen, food, and new seeds.

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.

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 is a molecule that absorbs light and synthesizes it into the energy, in turn giving plants life. Chlorophyll is primarily responsible for the photosynthesis process and hence performs as the basic building block of all life. It also gives plants

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

Light dependent reactions occur in the chloroplasts of a plant. Inside of chloroplasts are membranes called thylakoids, a folded membranous structure that holds chlorophyll. In order for the plant to make glucose, the plant must harness light energy and change it into chemical energy. In light dependent reactions, the plant uses light energy to make ATP and NADPH. The ATP is used in the next stage of the reactions, the light independent, also known as the Calvin Cycle. The light first enters photosystems I and II. The photosystems contain chlorophyll to help them capture the light. The light excites electrons which then passes its energy to another pigment molecule. When it passes its energy on, the electron drops into a stable energy level

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).

Chloroplast is an organelle. It is the cell in plants it contains chlorophyll.Chloroplasts absorb sunlight and mix it with water ,and carbon dioxide to make food and for the plant.Chloroplasts also then absorbs and collects light from the sun to produce the energy that is stored through a process called photosynthesis.Chloroplasts are one of the many organelles in the plant.In this respect they are similar to mitochondria. They are only found in plants..All organelles are surrounded by a cell membrane .They both have their own DNA, which are involved in energy metabolism; and both have reticulations, or infoldings, filling their inner spaces.Chloroplasts is commonly found in guard cells located in the plants leaves. Guard cells surround

Photosynthesis is one of the most important processes regarding living things. Photosynthesis is a process that plants undergo in order to produce food for themselves as well as giving off oxygen as a byproduct. Plants undergo photosynthesis because they are autotrophs, meaning that these organisms can gather energy from various non-living structures and store that energy in hydrocarbons (1). More specifically, most plants (including the elodea used during the lab) classify further as phototrophs. Phototrophs are organisms in which gathers the energy they use during photosynthesis from sunlight (1). The chemical equation which represents photosynthesis is as displayed below (2):

Photosynthesis is a process that plans protistans and some bacteria, use energy from the sun to create sugar. Cellular respiration turns into ATP which is fuel used by all living things. The transformation of sunlight energy into chemical energy, also goes along with the same process as green pigment chlorophyll. The photosynthetic process mostly uses water and releases the oxygen that is mandatory for us humans must have to live.

Photosynthesis is the process used by plants, algae and cyanobacteria to convert light energy from the sun into chemical energy for later use. The first stage in photosynthesis involves drawing moisture (H2O) and Carbon Dioxide from the surrounding area. The next stage in photosynthesis occurs when the light from the sun reaches the chloroplasts in the organism, for plants this is in their leaves, and for algae and cyanobacteria it happens in their antennae that collect the light. This light energy is used to convert the stored carbon and water in the organism into Glucose (C6H12O6) and Oxygen (O2). The glucose is stored in the organism whereas the oxygen becomes a byproduct of this reaction and is released into the immediate area. It is this

This lab allowed the experimenters to understand the effect of light on the producer’s photosynthesis. Once understanding how the light dependent reactions of photosynthesis worked, the experimenters can make predictions on how the light will affect the photosynthesis. For example, a low amount of light will affect the light dependent reactions of photosynthesis because light is essential for those reactions. The question the experimenters asked was, “Does having more or less exposure to light cause a faster rate of photosynthesis?”

     Photosynthesis is a biochemical process in which plant, algae, and some bacteria harness the energy of light to produce food. Nearly all living things depend on energy produced from photosynthesis for their nourishment, making it vital to life on Earth. It is also responsible for producing the oxygen that makes up a large portion of the Earth¡¦s atmosphere. Factors that affect photosynthesis are light intensity and wave length, carbon dioxide concentration, and temperature.
