Origin and Evolution of Plants
  • Life on Earth began about 3 billion years ago with prokaryotes (bacteria and archaeans). - Prokaryotes lack nuclei. - Photosynthesis arose 2 billion years ago in a cyanobacterium.
  • Organelles evolved, facilitating division of labor and specialization. - DNA became located in its own organelle, the cell nucleus. - Eukaryotes (plants, fungi, animals, algae) have nuclei and other membrane-bound organelles. - Eukaryotes diversified, some gaining
