Study Notes
Adaptation to the Environment
- Prokaryotes are organisms that lack membrane-bound organelles and are primarily unicellular.
- Most prokaryotes are heterotrophic, obtaining nutrients by consuming other organisms, while some are photosynthetic or chemosynthetic.
Taxonomy
- Taxonomy is the science of identifying, classifying, and naming organisms hierarchically based on evolutionary relationships.
- Organisms are categorized into various taxonomic ranks; for example, mushrooms belong in the kingdom Fungi and are multicellular and heterotrophic.
Kingdoms of Life
-
Protista: Eukaryotic organisms, mainly unicellular or simple multicellular, can be heterotrophic or photosynthetic, including protozoa, algae, and slime molds.
-
Plantae: Eukaryotic, multicellular, photosynthetic organisms that exhibit an alternation of generations and have cell walls made of cellulose.
-
Animalia: Eukaryotic, multicellular, and heterotrophic organisms with muscular movement capabilities and nervous systems for responding to stimuli.
-
Fungi: Eukaryotic, mostly multicellular organisms that are heterotrophic and digest food externally.
Properties of Life
- Organisms are composed of chemical elements and adhere to the same laws of chemistry and physics.
- Examples of organism classifications:
- Bacteria: Tiny, unicellular prokaryotes found everywhere, classified under kingdom Monera/Bacteria.
- Paramecium: A freshwater, unicellular protist, classified in kingdom Protista.
- Snow goose: A freshwater, unicellular animal that consumes food, classified in kingdom Animalia.
Characteristics of Life
- Living things exhibit specific characteristics that differentiate them from non-living things:
- Exhibit organization and hierarchical structure.
- Metabolize energy.
- Respond to stimuli.
- Reproduce and develop.
- Adapt to environmental changes.
Hierarchy of Life
- Organizational levels include atoms as the smallest units of matter, comprising protons, neutrons, and electrons, leading to more complex structures, from unicellular organisms to multicellular organisms like humans.
