  5. Learn about the key characteristics of plants and how they are classified into different groups based on their structure and reproduction. Explore examples of vascular and non-vascular plants, seeded and seedless plants, and more.

  6. OpenStax. Like animals, plants contain cells with organelles in which specific metabolic activities take place. Unlike animals, however, plants use energy from sunlight to form sugars during photosynthesis. In addition, plant cells have cell walls, plastids, and a large central vacuole: structures that are not found in animal cells.
