Electronic Flash differs from the consumable bulb flash in important aspects. Instead of creating light by burning up in an atmosphere containing oxygen, a consumable material (each bulb being used therefore only once), it produces a brilliant incandescent by discharging a current for a brief instant through a rarified gas, usually xenon. The gas glows every time the discharge is made through it but it is not consumed, so that many thousands of flashes are obtainable from a single tube, which helps to offset the much higher cost of the initial apparatus.

Plants are photosynthetic autotrophs, which means that they are able to produce their own food through the process called photosynthesis.

In photosynthesis, plants use light, water, and carbon dioxide to create glucose, which they convert to cellulose and use to make new cells.

Hence, that is why, Plants are called photosynthetic autotrophs.

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms activities.
