Study Notes
Evolution, Cell Biology, and Microbiology Overview
- Photosynthesis by bacteria led to a change in Earth's atmosphere, allowing new oxygen-breathing life forms to emerge.
- Symbiosis and endosymbiosis describe how different species benefit from living or working together, with mitochondria and chloroplasts as examples.
- The endosymbiotic theory explains the interdependence of a large host cell and ingested bacteria for survival.
- The diversity of life and the increase in antibiotic-resistant bacteria are evidence for theories on the evolution of life.
- Similarities between prokaryotes and eukaryotes suggest they originate from a common ancestor but have evolved independently.
- Differences between prokaryotes and eukaryotes include cell size, structure, and organization, as well as the presence of membrane-bound organelles in eukaryotes.
- Eukaryotic cells differ from prokaryotic cells in their larger size, presence of membrane-bound organelles, and multicellularity.
- Prokaryotic cells, including bacteria and archaea, are unicellular and have circular DNA, while eukaryotic cells are multicellular and have linear DNA.
- Features unique to prokaryotes include cell wall, different shapes, arrangements, motility, spore formation, and gram staining.
- Eukaryotic cells have diverse shapes and can be divided into plants, animals, fungi, and protists, with plants having cell walls and animals not.
- Major differences between bacteria and archaea include their cell wall composition, habitat, and cell division methods.
- Bacteria are ubiquitous and found in various environments, while archaea thrive in extreme conditions and reproduce asexually.
