Photosynthetic pigment

Sea slugs and aquatic plants have similar core features that allow both of them to acquire energy from light, but the sea slugs mechanism is far more involved and revolved around evolution. Elysia chlorotica, or the sea slug, have acquired the ability to conduct photosynthesis in their adult stages of life through their consumption of Vaucheria litorea. Vaucheria litorea are algae that are the primary diet of the developed sea slugs. Juvenile slugs acquire this ability when they ingest the algae…

light would offer a larger spectrum of colors compared to a blue or red pigment. To go into further detail there are four different photosynthetic pigments that are found in the chloroplast of a plant and these are chlorophyll b- yellow/greenish in color, xanthophyll-yellow colored group of carotenoids, beta-carotene-an orange colored carotenoid, and lastly chlorophyll a- blue/green in color. Chlorophyll a is the main pigment that is in plants and because it reflects in the green light…

layers of peptidoglycan and gram-negative bacteria have only few layers of peptidoglycan. The cell membrane of a bacterial cell has infoldings- mesosomes are intensely folded and are associated with DNA and also carry out respiration, photosynthetic membrane posses pigments and spread throughout the cell, nitrogen-fixing membrane is present in the cell membrane for fixing nitrogen. The capsule/glycocalyx is a stiff structure which is made of polysaccharides and…

hindering their ability to float. Final connection: as photosynthesis occurs, oxygen is released. The accumulation of it in leaves displaces the water and causes leaves to rise. With more intense light sources and higher levels of carbon dioxide, photosynthetic rates increase. Some possible errors in the experiment include an inconsistency in the distance and angle of the light. Some solutions include setting a precise position for the light and keeping…

contain much less peptidoglycan and unlike gram-positive bacteria, gram-negative bacteria contain lipoproteins. T. aquaticus appears as either a rod or short filaments. When exposed to sunlight, it can exhibit a yellow, pink, or red color due to pigments within the bacteria. Along with the coloration, T. aquaticus can either have flagella or be immotile. It thrives at 70 °C, but can survive at temperatures of 50 °C to 80 °C. This bacterium is chemotrophic— organisms that…

Global climate change: there is now sufficient evidence that global climate change, the emission an accumulation of greenhouse gases in the atmosphere, has had multiple effects on coral reefs. (Lesser, 2010) Terrestrial, aquatic and marine ecosystems are all affected by climate change. Coral is a vital part of the Great Barrier Reef ecosystem, without it there would be cascading effects. Coral bleaching is primarily caused by ocean temperature increase, but can also be caused by increased…

The process of photosynthesis is composed of two phases: light-dependent reactions and the Calvin cycle. The first stage (light-dependent reactions) occurs in the thylakoid membrane, which absorbs light energy to create NADPH and a proton gradient used to power the synthesis of ATP. The latter occurs in the stroma, and results in carbon dioxide fixation. In this experiment, only the light-dependent reactions were studied. 2,6-dichlorophenol-indophenol (DCPIP) was used as an artificial…

organisms generally consist of prokaryotes or eukaryotes, meaning species such as bacteria, archae bacteria, mycoplasma and cyanobacteria are included. The protista kingdom consists of aquatic, single celled eukaryotes. These eukaryotes are generally photosynthetic, including diatoms, golden algae, and protozoans. The Mycota kingdom (kingdom fungi) consists of mycelium, with hyphae bodies (long, thread-like structures). These organisms generally include saprophytes/parasites and symbionts. The…

organic compounds such as glucose. Plants and animals use glucose in the process of respiration to produce energy, while excreting Carbon-Dioxide, and Water. This Carbon-Dioxide that is excreted by the plants and animals can be used again by photosynthetic plants. Fish/Animals eat these plants and assimilate the Carbon into their bio-chemical structure. In this way, Carbon is passed along the food-chain. Eventually, the animals at the top of the food-chain die, and as they fall towards the…

epidermis and stretch across the length of the leaf to maximise light they can trap in the cells. The thing that allows the palisade cells to photosynthesize are the chloroplasts which contain chlorophyll. Chlorophyll is a name for closely packed green pigments that allow plants to absorb energy from sunlight. Sunlight is not so much an ingredient of photosynthesis but tool used to convert Carbon dioxide and water in glucose and oxygen. Therefore, provided there is enough carbon dioxide and…
