alkenes are everywhere and many have biological importance. the simplest alkene , ethene , is a plant hormone that regulates fruit ripeing , flower maturation , and seed germination. many of the pheromones that insects use to communicate alarm or find mates are alkenes, as are some of flavors and fragrances found in plants.

milk to curd, the ripening of a fruit, cooking of food and onset of monsoon after the unbearable heat of summer.
Do bananas really ripen faster left in a plastic bag?
As a banana ripens, it gives off ethylene gas. This gas is instrumental in the ripening process. In fact, it is this same gas that is used by banana importers to accelerate banana ripening once the bananas are ready to go to market. By placing bananas in a paper bag, you are concentrating the gas that is emitted from the fruit. As the concentration increases and the ripening process accelerates, more gas is emitted faster. Essentially, you have a chain reaction taking place -- more ripening means more gas, which means more ripening, and so forth.
Does the packaging affect the ripening of fruit?
Yes, packaging can affect the ripening of fruit. One way is by trapping the ethylene gas produced by the fruit, causing rapid ripening.
What is the differences between maturation and ripening?
Maturation is the full formation of the fruit or seed. Ripening is the process by which the seed receives the energy that it needs to grow.
How is auxin different from gibberellins and ethylene in terms of function?
Auxins are different from gibberellins and ethylene in terms of fruit ripening functions. Giberellins and Ethylene promote fruit ripening while Auxin slows down fruit ripening.
What are the uses of ethylene?
Fruit ripening.
How does Mango ripens by keeping it in a rice tin?
Ripening fruit generates Ethylene gas. If this gas is trapped around a ripening fruit in sealed bag or container it accelerates the ripening process.
What is the presence of oxalates in gauva fruit with ripening?
"What is the presence of oxalates in gauva friut with ripening?"
Is ripening of fruit a physical change?
Ripening is a chemical process.Ripening involve many chemical reactions.
Are tomatoes ripening created by ethylene or bacteria?
Ethylene promotes fruit (including tomatoes) ripening.
Is ripening fruit a irreversible change?
yes
Is auxin produced in cells of ripening fruit?
no
Does fruit ripen faster if placed in bag?
Ripening fruit in bagsYes. It can help to hasten the ripening process of some fruit if you place them in a paper bag. Ripening fruit release ethylene gas, and exposure to ethylene has been shown to hasten ripening, so placing the fruit in a closed bag traps the ethylene and facilitates ripening. This only works for fruit that ripen after being harvested. Apples, pears, peaches, plums, and bananas, to name a few, will benefit from being placed in a bag. Citrus fruit -- oranges, lemons, grapefruits -- will not ripen after they're picked.
What is ripening define?
Ripening is a process in fruit that causes them to become more edible. In general fruits become sweeter, less acidic, less green and softer as they ripen. Fruit ripening can be regarded as a senescence or ageing process.
