  • Many plants grow without soil. Soil is not food for plants.

Why Do We Need To Know About Plant

Learning about plants helps us see how everything in nature is connected and shows us why jobs in environmental and agricultural sciences are important. Plants feed both people and animals, which is key for farming and food production. This means knowing how to grow plants well is important for keeping our food supply going and taking care of the planet. Plants also make the oxygen we breathe, which is why jobs that focus on keeping our air clean and fighting climate change are important.

Plants help stop soil from washing away. They also give us materials for our homes. Knowing what plants need to grow and how to experiment to find the best conditions for growth, is important for jobs in farming and environmental science. This knowledge helps make better products, improve how we grow plants, and ensures our planet stays healthy.
