Study Notes
Introduction to Organisms
- Organisms are living objects, distinct from inert objects due to their ability to reproduce.
- Organisms require a set of instructions (e.g. genetic material) specifying characteristics passed to offspring.
- Organisms' complexity and adaptation to diverse environments have evolved through a process (i.e. evolution or natural selection).
Classification of Organisms
- Organisms are categorized into 5 broad kingdoms: Monera, Protista, Fungi, Plantae, Animalia.
- The taxonomic system categorizes organisms into hierarchical groupings including kingdoms and others.
- Monera (e.g. bacteria) lack a membrane-bound nucleus and intracellular membranes.
- Protista (e.g. algae, protozoa) are eukaryotic, meaning they have membrane-bound organelles.
- Fungi (e.g. mushrooms) are eukaryotic but lack chlorophyll and obtain nutrients from external sources (e.g. decomposing matter).
- Plantae (e.g. plants) are eukaryotic with chlorophyll and conduct photosynthesis for energy.
- Animalia (e.g. animals) are eukaryotic, multicellular, and obtain nutrients by consuming other organisms.
Additional Information About Organisms
- Some bacteria cause disease.
- Photosynthesis occurs in some organisms, enabling them to convert light energy into chemical energy.
- Fungi, like animals, obtain food in pre-formed states, but not like animals, can digest food externally.
- Some algae, like brown and red algae live strictly in water (e.g. sea water).
- Green algae primarily reside in aquatic or very moist environments.
- Vascular plants are divided into 3 main groups: the ferns, gymnosperms, and angiosperms.
- Most advanced plants are angiosperms (e.g. flowering plants)
- Animals obtain food internally and have characteristic features, like an internal skeleton that support their body structure .
- Echinoderms (e.g. sea stars) are strictly marine.
- Vertebrates have a backbone as part of a skeleton.
