Chlorophyll Essays

The chloroplast is another organelle that is used by the cell to convert and make energy. By absorbing energy from the sun and using the energy in addition to water and carbon dioxide in a process called photosynthesis, to make sugar and release oxygen, chloroplasts can convert sunlight into usable chemical energy for the cell. Chloroplasts are only found in photoautotrophs, which are primary producers such as, photosynthetic algae and plant cells. All of the other organisms that are consumers depend

dioxide, ATP, and NADPH while the outputs are sugar, ADP, NADP+, and inorganic phosphate. The pigments utilized in light reactions are chlorophylls a and b and both occur within the thylakoid sacs of the chloroplasts. The focus of this experiment is to determine which photosynthetic pigments are prevalent in the spinach plant. I hypothesize that chlorophylls a and b will more abundant than other pigments. Methods

heights among the three different plants, the results came to being blue light has the greatest impact. Blue light has a higher rate for absorption in the pigments. Pigments in the thylakoid membrane (chloroplast), contain two key types, chlorophyll a and chlorophyll b, these types have a slight difference in structure but absorb the blue and red wavelengths. Other accessory pigments absorb these photons between the red and blue spectrum (orange, yellow, green, etc). Another reason for the height is

convert light energy into profitable chemical energy. The reaction of photosynthesis is different or reverse of cellular respiration. Light energy is essential for photosynthesis. Photosynthesis occurs in chloroplasts which have chlorophyll inside. Chlorophyll a, chlorophyll b, xanthophyll, and carotenes are major photosynthetic pigments which are found in chloroplast of the plant. The amount photosynthesis affected by the color of light as the amount of light absorbed in different color. Green plants

We know that Chlorophyll is more of a dominant pigment in green plants, in which hides the color of the Carotenes and Xanthophyll among the leaves. In this lab, we can easily separate these different pigments, through chromatography. What this does it separates mixtures

The purpose of this experiment is to study how much light is being absorbed by chloroplasts at different wavelengths for photosynthesis. The other goal is to learn if different color of leaves had different absorbance from green colored-leaves. For this experiment, two different color (purple and green) of Kale (Brassica oleracea var. sabellica) were used in the following experiment. The pigment from each leaves were extracted by grinding the tissue in 5 ml of 100% acetone using a mortar and pestle

paper. Chlorophyll a is one primary photosynthesis pigment of all photosynthesis organisms. There is also addition pigment, which are chlorophyll b, β carotene, xanthophylls, phycoerythrin, and phycocyanin. Those assists by transferring the light energy and Light energy absorbs to chlorophyll a. The paper chromatography separate pigment based on their physical characteristics. Hypothesis: My hypothesis for this experiment will be that chromatography paper will separate color of chlorophyll extract

only apply to plants, it also applies to any autotroph, some of which include, bacteria and algae. The photosynthetic process depends on a set of complex protein molecules that are located in and around a highly organized membrane in which chlorophylls- pigments that are responsible for the absorption of light to create energy- are able to capture the sunlight and further transform into glucose and ATP energy. See figure 1. This is because photosynthesis is light dependant, meaning that low

Cyanobacteria or cyanophyta is commonly known as blue-green algae which is a type of bacteria. The colour pigment they have is from phycocyanin along with chlorophyll. Chlorophyll is in all green plants, algae and also cyanobacteria which helps them absorb light to create energy to be able to perform photosynthesis. Cyanobacteria grows at the ocean shore or pools and ponds at their edges although they can be found in soil, water and salt water. Cyanobacteria live in sheets like films, but thin enough

The hormone cytokinin causes this after the exposure of light. Chloroplasts contain chlorophyll and due to this the plant turns green. 1.1 Research question For this experiment, I want to find out what will happen to cress seeds that are etiolising (growing in the dark) when they are then exposed to light. To conduct this experiment, I came

existing in a wave. Thus, the shorter the wavelength, the more energy it contained. This is in contrary to the longer wavelength. White light originating from the sun consists of a whole spectrum of visible light wavelengths (ranging 400nm to 750nm). Chlorophyll in chloroplast traps the sun’s light in two parts (red (680nm) and purple (400nm to

the sunlight and water are taken in by the chlorophyll where they are converted into oxygen and it exits through the stoma. The chlorophyll additionally produce the chemical energy ATP and NADPH which are taken to the Calvin Cycle. This is where carbon dioxide and chemical energy produce glucose and cellulose (which serves as food for the plant; it exits phloem of the plant, located in the veins. As stated above, the thylakoid, chloroplast, chlorophyll, ATP, and NADPH are the cell parts involved

process of making smaller particles into larger ones in metabolism, that plants use to convert reactants such as sunlight, water, and carbon dioxide into products of glucose and oxygen. Photosynthesis occurs in the chloroplasts of a plant cell where chlorophyll, a pigment, is used to allow the process to occur, while factors such as the amount of sunlight, water, and carbon dioxide affect how much photosynthesis occurs. Chromatography is the process of separating chemical mixtures by allowing chemicals

photosynthetic organ of green plants. Plants carry out the process of photosynthesis to convert carbon dioxide and water into oxygen and glucose for usable energy. This can be represented in a general equation which is 6CO2 + H2O -------> (sunlight and chlorophyll) C6 H12 O6 +6O2. Initially, the leaf is protected by the upper and lower epidermis as well as the cuticle. The leaf first needs to obtain sunlight which enters through the cuticle. Eventually, the sunlight seeps through to the upper epidermis and

Certain wavelengths are absorbed; others are reflected; when certain wavelengths are reflected, color is produced. This is the reason behind why plants are green. Because the main pigment chlorophyll absorbs all colors in the visible light spectrum but green. Plants also feature accessory pigments which are chlorophyll b and carotenoids. These different pigments absorb different wavelengths/frequencies of light except green. The use of accessory pigments is to capture and absorb most of the wavelength

How Calcium Effects Bean Plants Photosynthetic Rate Tristen Webber Introduction In this study I measured the growth of a bean plant over 13 days and then measured the photosynthetic rate by measuring the amount of chlorophyll a in the leaves of the plants. Photosynthesis is the process of plants creating glucose from, water, carbon dioxide and sunlight. Photosynthesis depends on the absorption of light from pigments in the plants leaves. I tested how calcium would affect the photosynthetic

Carbon Dioxide gas is a reactant that enters plants through tiny openings in the leaves of plants. Carbon and oxygen atoms are used in the formation of glucose during photosynthesis. Plants absorb the light from the sun by using the reactant chlorophyll. Chlorophyll also is the reason many plants have their green color. The products of photosynthesis are extremely important because they both are used and needed by many animals and humans. Glucose is an important product of photosynthesis, the energy

Doriana Spurrell What different frequencies and types of light would prompt the Spinach leaves to go through the process of photosynthesis effectively? Purpose: The purpose of this experiment was to see which of the four lights that range across the light spectrum would properly and most efficiently help the spinach leaf perform photosynthesis. Background Information: Photosynthesis is the process in which plants use light energy to transform into chemical energy. The process of photosynthesis is

the photosynthetic process. There are two types of colored pigments: yellow pigments or carotenoids, and green pigments or chlorophylls. Both categories of pigments also include other types of pigments and all are essential for carrying out photosynthesis and each have a role for helping plants receive energy (Pavia et al 208). In this experiment, carotenoids and chlorophylls were extracted from spinach leaves using techniques of column chromatography and thin-layer chromatography. Column chromatography

photosynthesis rate will increase. This is because as light intensity increase, the rate of light-dependent reactions increase since light dependent reactions use light as an energy source. When light hits the surface of the leaf, it is absorbed by chlorophyll pigments. The light dependent reaction takes place in the chloroplast, more specifically the thylakoid membrane.
