What exactly is a plant?
Does a plant have to be green? Do they all photosynthesize? Are there plants that can move from place to place? How do plants reproduce? These questions and more will be addressed in the Plants chapter.
Plants is an in-depth look at the Kingdom Plantae, from small nonvascular plants to towering redwood trees. It is probable that without plants, most life, including us, would not exist. Why? Photosynthesis. This process brings energy into our ecosystems and produces the oxygen that all our cells need. This concept discusses the types of plants, the structures of plants, the life cycles of plants, and the adaptations and responses of plants.
