What exactly is a plant?
Does a plant have to be green? Do they all photosynthesize? They are eukaryotic organisms that are not animals, fungi, or protists. And yes, they have to photosynthesize.
The Kingdom Plantae ranges 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 of our cells need. This concept discusses the types of plants, the structures of plants, reproduction of plants, and the adaptations and responses of plants.
