Study Notes
Plants play a crucial role in our ecosystem by producing oxygen through a process called photosynthesis. This process occurs when plants absorb light energy from the sun using pigments like chlorophyll found within their leaves. With this light energy, they convert carbon dioxide into glucose and oxygen via the Calvin Cycle. Photosynthesis is essential because it allows plant life forms to grow and thrive while also providing us with fresh air to breathe. Without photosynthetic organisms, there would be very little oxygen present in Earth's atmosphere, making human survival impossible. While many people think of trees primarily for their wood products or beauty, understanding how these structures work together can help us better appreciate all they do for us.
