Final answer:
The amount of light a plant receives affects its growth rate by enabling photosynthesis, which provides energy for growth. Too little or too much light can negatively impact a plant's growth. Finding the right balance of light is crucial for optimal growth.
Step-by-step explanation:
The amount of light a plant receives has a significant impact on its growth rate. Light is essential for photosynthesis, which is the process by which plants convert light energy into chemical energy to fuel growth. Without light, photosynthesis cannot occur, and therefore, growth is limited. Too much light can also be harmful to plants, as they may become overwhelmed and stressed. Different plants have different light requirements, and finding the right balance is crucial for optimal growth.
