Study Notes
Introduction to Diversity in Plant Life
- Study of plant diversity includes mosses, ferns, conifers, flowering plants, fungi, and algae.
- Key aspects of diversity: classification, habitat, life forms, size, life cycle, nutrition, and economic importance.
Classification of Living Things
- Over 5 million organisms exist, necessitating systematic classification.
- Taxonomy is the discipline for organizing living things based on shared characteristics.
- Latin names have been used for organisms since the Middle Ages, evolving from descriptive polynomials to the binomial system.
Binomial Nomenclature
- Carolus Linnaeus simplified classification in the 18th century with the binomial system.
- Scientific names consist of two parts: generic name and specific epithet (e.g., Lathyrus odoratus).
- Names printed in italics or underlined; specific epithets require genus for clarity (e.g., L. odoratus).
Major Groups of Living Things
- Classification can reflect genetic relationships, known as phylogenetic classification.
- Key criteria for plant categorization include photosynthetic pigments, leaf structure, vascular tissue, and reproduction methods.
Prokaryotes vs. Eukaryotes
- Prokaryotes: Lack true nuclei and membrane-bound organelles; reproduce mainly through cell division; single circular DNA; include Kingdom Monera (bacteria and cyanobacteria).
- Eukaryotes: Have defined nuclei and organelles like mitochondria; exhibit multicellularity and sexual reproduction; cell communication through structures like plasmodesmata.
Uni- and Multicellularity
- Most plants are multicellular and photosynthetic, existing both in aquatic and terrestrial environments.
- A few species are unicellular, showcasing the diversity of life forms within plants.
