Plant Life

Today is Earth Day and we are going to explore the life cycle of plants. Plants start out in the form of a seed. A seed in the ground that is regularly watered will germinate. Once this happens it starts to grow its taproot downward into the soil. The taproot is the main root that all other roots branch from. It also grows its cotyledons, which are the first set of leaves that emerge above the soil. Pictured above is a plant in its early stages of life.

After many years of adequate water and sunlight, that little tiny plant turns into this big tree (pictured above), which contain more seeds in order to reproduce and start the entire process over again. Trees absorb water through its roots. With its leaves, it uses sunlight to produce food (carbohydrates) from water and carbon dioxide and creates a byproduct of oxygen in a process called, photosynthesis.

Did you know, what makes the leaves of a plant green? This is because they contain a pigment called chlorophyll, which absorb blue and red parts of the light spectrum and reflect the green light, making the plant appear green.
