- Leaves are a plant’s food factory. Leaves make glucose using the energy of the sun, water and carbon dioxide through the process of photosynthesis. Oxygen is also a product of photosynthesis.
- Chlorophyll is the green pigment that gives leaves their green color and helps make photosynthesis possible.
- Deciduous trees are loss their leaves in the fall. These leaves are generally large and flat.
- Evergreens stay green year round, as their name implies. Their leaves are actually needles.
- As the days get shorter and cooler in the fall, the process of photosynthesis slows down and the tree begins to use some of its stored energy. As a result, the true color of the leaves can show through.
- That’s right! The beautiful colors of the fall are the actual colors of the leaves, but the chlorophyll is masking the colors during the spring and summer while photosynthesis is occurring.
