light:How do plants use UV light?

How do plants use UV light?

Some insects like bees eery different of colours from see, and they IN light. Bees ery important due, for they Pollen from one another. These are brightly to attract ke bees. Some ire a bright red,
a colour that bees can't see. This is where UV light plays a role. The red flowers reflect UV light- which is a colour that is visible to the bee. The bee is then attracted to the red flower, n d flies to it to drink its nectar- and in the process, get some pollen on its body that will be transferred to another flower. When some materials are lit by UV light, they emit a fluorescent glow. Some such chemicals are used in laundry detergents as whiteners. They bind to the natural fibres in clothes, and make them look brighter in sunlight. Ultra violet light is used to kill bacteria, hasten chemical reactions, and to identify some fluorescent minerals. UV light can also be used to show things the human eye can't see, which makes it very useful for forensic scientists.
