Plants & Botany
Explore plant biology from the molecular machinery of photosynthesis to the ecological roles plants play in nearly every terrestrial ecosystem. Science University explains how light energy is converted into chemical energy, how plant cells support growth and metabolism, and why plant processes matter for food webs, atmospheric chemistry and climate. The emphasis is on mechanisms rather than memorized labels, with reliable sources for key factual claims. Use this hub to build a stronger understanding of botany and plant function.
