Plants

Plants form a kingdom which includes groups that reproduce by spores, such as mosses and ferns, and groups that reproduce by seeds, such as conifers and flowering plants. Plants get their energy through photosynthesis, using sunlight to convert water and carbon dioxide into sugar and releasing oxygen as a by-product - perhaps the most important biological process on Earth.
