Oxidation is a process in which something (an atom or molecule or substance) loses an electron to something else. Photo-oxidation is therefore the process of oxidation which is caused by shining light on it. Often, light can be used to cause reactions to happen, such as oxidation. The term "photo" comes from "photon" which is light.

Why do sample should be keep in dark place for 30minutes in determination of iodine value?
Samples are kept in the dark for 30 minutes in the determination of iodine value to prevent the oxidation of unsaturated fats by light. Exposure to light can cause the fats in the sample to undergo photooxidation, which can result in inaccurate measurement of the iodine value.
Would the earth have soap if plants did not exist?
No, the earth would not have soap if plants did not exist. I believe this because soap plants (of the genus Chlorogalum) are essential to our making of soap. We use these plants to make all kinds of soap, by using the sap of these plants. However because this does not complete the question, I will explain further. Plants are the only way that the compound 'saponin' exists. Saponin forms the bubbly lather.
What are plants without chlorophyll?
Plants without chlorophyll are called achlorophyllous plants. They are incapable of photosynthesis and rely on obtaining nutrients from other sources like fungi or through a parasitic relationship with other plants. Examples include Indian pipe and broomrape.
What gas do plants produce for the atmosphere?
Plants produce an excess of oxygen which is released into the atmosphere. This is a product of photosynthesis.
What pigment only present in plants makes photosynthesis possible?
Chlorophyll is the pigment that is responsible for absorbing sunlight energy needed for photosynthesis in plants. It gives plants their green color and is found in chloroplasts.
What has the author John Homer written?
John Homer has written: 'A brief sketch of the present state of the province of Nova-Scotia' -- subject(s): Commerce, Economic conditions 'Primary processes in the photooxidation of polyolefins'
Does milk have chlorophyll in it?
It has been found that milk contains chlorophyllic compounds in very low concentrations. Not exactly chlorophyll a or b, but probably breakdown products from these. Milk also contains porphyrins such as protoporphyrin and hematoporphyrins. All these compounds contribute to the photooxidation in milk since they are very light sensitive.
When a newspaper is left in direct usnlight for a few days the paper begins to turn yellow The yellow color is evidence of a what?
The yellow color on the newspaper is evidence of oxidation and chemical breakdown of the paper fibers due to exposure to sunlight. This process is known as photooxidation and it causes the paper to lose its brightness and become yellow over time.
How does nature take action against an oil spill?
Nature can degrade oil through natural processes like evaporation, photooxidation, and biodegradation by microorganisms. Sometimes, natural oil-degrading bacteria can help break down the oil, reducing its impact on the environment. Additionally, waves and currents can disperse the oil, helping to naturally dilute and minimize its effects.
How does recycling pollute plants and animals?
Because plants are plants and plants are plants which means plants are plants and plants are plants

Why is photorespiration wastful process?
Photorespiration is considered wasteful because it consumes energy and resources without producing useful compounds for the plant. It occurs when rubisco enzyme fixes oxygen instead of carbon dioxide, leading to the release of CO2 and consumption of ATP and reducing power. This process reduces the efficiency of photosynthesis and can limit plant growth in certain conditions.
Are pitcher plants nonvascular or vascular plants?
Pitcher plants are vascular plants.
How can plants be dangerous?
There are poisonous plants and carnivorous plants
What do you think when you classified plants?
Talking about classification of plants: Plants can be classified into 3 groups. SHORT DAY PLANTS LONG DAY PLANTS DAY NEUTRAL PLANTS
