Study Notes
Classification of Living Things
- Taxonomy is the science of classifying living organisms based on shared characteristics and evolutionary relationships.
Prokaryotes
- Prokaryotes are unicellular organisms lacking a nucleus and membrane-bound organelles.
- They are divided into two domains: Bacteria and Archaea.
- Bacteria are diverse and can be found in various environments, including soil, water, and even within the human body.
- Archaea are similar to bacteria but differ in their genetics and biochemistry, often found in extreme environments.
Eukaryotes
- Eukaryotes are organisms with complex cells containing a true nucleus and membrane-bound organelles.
- They are classified into four kingdoms: Protista, Fungi, Plantae, and Animalia.
Kingdom Protista
- Protists are mostly unicellular eukaryotes, although some are multicellular.
- They are diverse and include algae, protozoa, and slime molds.
- Protists are typically found in aquatic environments but can also inhabit moist terrestrial habitats.
Kingdom Fungi
- Fungi are mostly multicellular eukaryotes, although some are unicellular (yeasts).
- They obtain nutrients by absorbing organic matter from their surroundings.
- Fungi include molds, mushrooms, and yeast and play crucial roles in decomposition and nutrient cycling.
Kingdom Plantae
- Plants are multicellular eukaryotes capable of photosynthesis.
