Plant biology, or , is the scientific study of plant life, focusing on their structure, growth, reproduction, and metabolism. Plants are unique organisms that convert sunlight into energy and serve as the foundation for most ecosystems on Earth. 1. Core Anatomy & Structure

: Vascular plants that reproduce via spores (e.g., ferns). Gymnosperms : "Naked seed" plants like conifers.

: Flowering plants that produce seeds enclosed within a fruit. 4. Recommended Resources

To survive and grow, plants undergo several complex processes:

Plants are multicellular organisms with specialized structures that allow them to thrive in various environments.

: Often called the "kitchen" of the plant, they are the primary site for photosynthesis and gas exchange through microscopic openings called stomata . 2. Key Biological Processes

: A unique life cycle where plants alternate between a multicellular haploid phase ( gametophyte ) and a multicellular diploid phase ( sporophyte ). 3. Major Plant Groups
