Study Notes
Botany and its Subdisciplines
- Botany is the scientific study of plants, encompassing their structure, properties, biochemistry, classification, and environmental interactions.
- Plant anatomy studies plant internal structures at the tissue and cellular levels.
- Plant physiology examines plant functions like photosynthesis, respiration, and nutrient absorption.
- Plant taxonomy classifies and names plants, focusing on identification, nomenclature, and categorization.
- Plant ecology investigates plant-environment interactions and relationships with other organisms.
- Plant genetics studies plant heredity, including gene structure, function, and variation.
Living vs. Nonliving Things
- Living organisms share characteristics: cellular organization, metabolism, growth and development, reproduction, response to stimuli, and homeostasis.
- Nonliving things lack these characteristics; they are not cellular, don't metabolize, reproduce, or respond to stimuli like living organisms.
Biological Classification: Kingdoms and Domains
- Six Kingdoms: Archaebacteria (extremophile bacteria), Eubacteria (common bacteria), Protista (single-celled eukaryotes), Fungi (decomposers), Plantae (photosynthetic plants), Animalia (multicellular heterotrophs).
- Three Domains: Bacteria (true bacteria), Archaea (ancient microorganisms), Eukarya (eukaryotic organisms including Protista, Fungi, Plantae, and Animalia).
The Scientific Method
- The scientific method involves observation, hypothesis formulation, experimentation, data analysis, conclusion drawing, and publication.
- Science is empirical, evidence-based, and focused on reproducible results, unlike subjective fields like philosophy or art.
Contemporary Global Challenges and SDGs
- SDG 2 (Zero Hunger): Aims to end hunger, ensure food security, and promote sustainable agriculture.
- SDG 13 (Climate Action): Prioritizes urgent action against climate change and its impacts.
- SDG 15 (Life on Land): Focuses on protecting, restoring, and sustainably using terrestrial ecosystems; managing forests; combating desertification; and halting biodiversity loss.
