1) Bioluminescence/ fluorescence: Bioluminescence can be used to describe an organism that glows or releases a flash of light, particularly when disturbed. Fluorescence on the other hand can be defined as a process where light energy excites electrons to a higher energy state and that emits a photon when returning to ground state excitation. A major difference between the two is that bioluminescence is chemical process that involves enzymes and the breakdown of substrates that result results in light as a product; whereas fluorescence is physical process that relies on changes in electron excitation. Organisms such as certain algae, bacteria, fungi, squid, insects and fish use bioluminescence for several different purposes, such as to scare off predators or to lure prey (anglerfish), to attract mates (lanterneyes fish), and communication. Fluorescence serves several purposes as well, such as in chromosomal fluorescent staining techniques or gemology.
2) Endoplasmic reticulum/ Golgi complex: The endoplasmic reticulum (ER) is responsible for the modifaction of fats and lips, the

Daily fluctuations in the amount and availability of light make circadian rhythms necessary in such a way that, for example, in humans we sleep during the night so that we can utilize the availability of light energy, photons, during the day. This fluctuation in availability of photons has a pronounced effect on biological processes such as DNA replication and photosynthesis; UV light that comes company with visible light from the greater electromagnetic radiation spectrum, produces an effect that typically only allows for DNA replication to occur at night for most organism, the proteins used during photosynthesis to be produced before dawn, and allows for photosynthesis to fully utilize the day portion of the light cycle to generate usable
The smooth endoplasmic reticulum is responsible for production and packaging of lipids and steroids. (Plant Cell Anatomy, n.d.)
In the effect of light wavelength experiment, the action spectrum is used to demonstrate the effectiveness of various wavelengths of light on photosynthesis. To observe these effects of the wavelengths the wavelength pigments red, blue, green, white light, and no light are used. In the experiment, spinach leave disks were aspirated in a sodium bicarbonate solution in order to remove all internal gases and make the disks sink to the bottom of a beaker. Each beaker full of 10 spinach disks was placed into a different box with a different colored light source.
In this lab, varying wavelengths were used to test how light affects photosynthesis and respiration as a whole. The absorbance of lights from 380 nm to 720 nm of chlorophyll pigment from the Elodea sample
Fireflies are able to light up because inside their body, there there is a chemical reaction produced. The light production is also known as bioluminescence. The best known example of bioluminescence is the production of light by fireflies. In presence of luciferase, adenosine triphosphate (ATP) and the chemical luciferin in the presence produce light when oxygen combines with calcium. A firefly’s light is cold light and causes less energy is lost as heat which makes it special than light bulb. In a light bulb, a lot of heat in addition to
When [A] is luminol and [B] is hydrogen peroxide, a suitable catalyst then evokes the reaction:
Being able to see in the dark often does not come easy. For humans, we typically need to find a flashlight, and more times than not, find new batteries to power the device. For animals, it can be different. Some animals may see fine and night, and some animals have large eyes like owls that capture lots of light, and some animals use other senses to gather information about their surroundings. We humans on the other hand are left fumbling for candles when the power is out for any length of time. But there are some life forms that have a completely different approach – bioluminescent life forms. Bioluminescence life forms make their own light and carry it around in their bodies. This paper will address bioluminescence and try to
Natural and artificial light have varying properties that affects their capability and appropriateness these properties regularly impact their surroundings. Natural light comes in a spectrum of colours, which are the visible rays. Also on the colour spectrum are shorter wavelengths, named ultraviolet rays and higher wavelengths, known as infrared rays. Both of these are not visible to us. Exposure to the sunlight can help
Photosynthesis is a vital process that autotrophs use to transfer light energy into chemical energy. Photosynthesis ultimately produces O2 and glucose. It, like many other biological processes, can be affected by environmental variables. The variable that we altered in the following experiment are intensity, light wavelengths, and pigment types. In order to do this, we conducted three experiments. In the first experiment, we examined the effect of light intensity by placing vials with chloroplasts with DPIP at different light distances in which the results varied. Initially, 30cm away was the most effective for photosynthesis. Then 24cm appeared to be the most effective. Followed by 49cm at minutes 25 and 30. In the second experiment, we
Obvious light ranges from approximately 750 nm in the red to 380 nm in the blue. Regarding vitality, our equation lets us know that these photons range from around 1.6 to 3.3 electron volts. This is generally on the request of the energies included in electron vitality levels, which is the premise for science. Synthetic responses can make noticeable light (shine stocks, fireflies, and so on) and light can made substance responses (camera film, colours blurring, and so on). Bright light from the sun is of a shorter wavelength, say, 300 nm or somewhere in the vicinity from the beams we ought to shield ourselves from at the shoreline. These are around 4.2 eV, sufficiently solid to more energize more enthusiastic electron vitality levels and separate the particles. On the off chance that it's a DNA atom, these harms and breaks from retaining the photons can in the long run lead to skin growth and other wellbeing
Both the firefly and the firefly squid create light with a chemical called luciferin. When it combines with other chemicals, luciferin produces a light without heat. The structure of luciferin molecules in an animal’s body determines the color of the light – it
1. An example of this would be our response to light. We follow a circadian rhythm of being awake in the daytime, and sleeping when it is dark outside.
The name for these bacteria is Luminescent bacteria. They produce light through a chemical reaction in which chemical energy is converted into light energy. Many deep sea organisms have this chemical reaction. Some species of luminescent bacteria possess quorum sensing, which allows them to light up when there area is populated.
The first thing to note is luminescence is a generalized term describing the production of visual light with a lack of radiant heat termed “cold light”. Three main categories describe the types of luminescence (please refer to Table 1); biological, chemical and physical. Bioluminescence is another broad term defining any form of luminescence produced by organisms, predominantly seen in marine species. This phenomena is seen in some species of cephalopods of the Tesuthida (squid) order and many of the members of the

Bacterium has a symbiotic relationship with its host and is contained in an organ inside the animal (Lin). Many marine animals use both of these processes to produce a desired light source.
