Light affects plant growth in three ways, including quality, quantity and duration. All of these must come together in the proper balance to ensure optimal growth of a plant.
Quality addresses the wavelength or color of the light that hits the surface of the plant. Sunlight may be a prism of different colors, including red, yellow, blue, violet, orange, green and indigo. Weather events such as rain can work similar to a prism and cast different colors. Quantity means the concentration or intensity of the sunlight the plant is receiving, and duration refers to how long the plant is getting sunlight.Learn More
The process of gaseous exchange in plants happens in the leaves. Oxygen and water vapor leave the plant while carbon dioxide enters through pores called stomata. Plants require carbon dioxide for photosynthesis and oxygen for respiration.Full Answer >

Trees lose their leaves in the winter as they enter their dormant period in order to protect cells from freezing temperatures. In this stage, they no longer need the food that the leaves produce. Trees respond to changes in available light and begin to form a layer of dead cells in the stem of their leaves, so each leaf breaks from the limb and falls to the ground.Full Answer >
