Plant life refers to the vast variety of living organisms that belong to the kingdom of Plantae. These organisms, which include trees, flowers, and grasses, play a crucial role in our ecosystem. They produce oxygen through a process called photosynthesis, using sunlight, carbon dioxide, and water. This not only helps plants grow but also supports all living creatures by providing the air we breathe. Plants come in many shapes and sizes, adapting to different environments around the world. Some, like cacti, thrive in dry deserts, while others, like ferns, flourish in damp forests. Each type of plant contributes to its habitat, offering food and shelter to various animals and insects, creating a balanced ecosystem.
