What is the function of light bulb?

Answer 1

To provide illumination by passing current and therefore, making it react with the gases inside the bulb and "light" up.

Answer 2

Bulbs are normally produced by plants to either store food or for protection from animals and adverse weather/ climate. A bulb is also a method of self replication via asexual reproduction (formation of adventitious bulblets). Most true bulb plants are monocotyledonous

For example: The Protoasparagus plant grows in semi-arid areas, it produces storage organs beneath the soil to store water and food for times when the climate is dryer and rain less frequent. It also protects the plant from dying completely in times when the temperatures may be high enough to kill the foliage above the ground. It also protects the plant in the case of fires that may ravage across the ground and kill the foliage.

Example: The Lily bulb, here the plant generates the new leaves from the centre of the bulb (which is below ground) during the spring and summer seasons. When the weather changes the frost and snow kill off the foliage that is above the ground; the bulb enables the plant to remain protected and dormant beneath the soil until the following spring.

Examples of bulbs include:

Agapanthus, Alstroemeria, Caladium, Canna, Clivia, Daffodil, Garlic, Onion, Tulip and Zantedeschia

Answer 3

A 'bulb' or, more correctly, a 'lamp' produces light. There are many types of lamp but, probably the most common type used in the home is the incandescent lamp which works by raising the temperature of its filament until it glows brightly.

Answer 4

A bulb stores nutrients for the plant to use in its next year of growth. It enables the plant to survive dry seasons.

Answer 5

A light bulb makes dark places light

Answer 6

the function of an bulb is it to light up
