The energy that is taken in by plants is supplied by sunlight
The energy that is taken in by plants is supplied by sunlight. Sunlight is a form of electromagnetic radiation that contains energy in the form of photons.
Plants have a special pigment called chlorophyll, which is responsible for absorbing sunlight. Chlorophyll is mainly found in the chloroplasts of plant cells, specifically in structures called thylakoids.
When sunlight hits the chlorophyll molecules in the thylakoids, it excites the electrons within the pigment. This energy is then used to power a series of reactions known as photosynthesis. Photosynthesis is the process through which plants convert solar energy into chemical energy in the form of glucose (a sugar).
During photosynthesis, the absorbed sunlight is used to split water molecules into oxygen and hydrogen ions. The resulting oxygen is released into the atmosphere as a byproduct, while the hydrogen ions are used to generate chemical energy in the form of adenosine triphosphate (ATP) and another energy carrier molecule called Nicotinamide adenine dinucleotide phosphate (NADPH).
These energy carriers, ATP and NADPH, are then utilized in the second phase of photosynthesis called the Calvin cycle, where carbon dioxide from the atmosphere is converted into glucose. Glucose is a form of chemical energy that plants can use for growth, metabolism, and other cellular processes.
Therefore, sunlight acts as the primary source of energy for plants, and through the process of photosynthesis, plants are able to convert this light energy into chemical energy in the form of glucose, ultimately supplying the energy they need for survival and growth.
