PHOTOSYNTHESIS IN PLANTS
All living things require food: humans and plants eat other animals or food, but plants cannot eat like humans and animals. Plants obtain food by preparing it on their own by a process called photosynthesis.
Therefore, the most important process triggered by light in plants is photosynthesis. The faster the photosynthetic rate, the faster the plant grows. The rate of photosynthesis is impacted mostly by the light intensity and quality. There are 2 key factors that impact the photosynthesis rate: Light intensity and spectrum.
