Study Notes
The Living World
- Being alive is characterized by a complex organization of molecules that engage in chemical reactions leading to growth, development, responsiveness, adaptation, and reproduction.
- Distinctive functions of living organisms include:
- Growth: Permanent and irreversible increase in mass, with multicellular organisms exhibiting determinate (e.g., humans) or indeterminate (e.g., plants) growth patterns, while unicellular organisms increase in number.
- Reproduction: Essential for the continuity of life.
- Metabolic Functions: Catabolism (breaking down substances) and anabolism (building up substances) are crucial metabolic processes.
- Cellular Organization: Living organisms possess a definite cellular structure.
- Movement: Ability to move and demonstrate locomotion.
- Adaptability: Organisms adjust to enhance their survival rates.
- Respiration: Energy generation occurs through aerobic or anaerobic processes.
- Homeostasis: Maintenance of stable internal conditions.
- Consciousness: Ability to sense and respond to environmental stimuli.
- Aging and Death: After a growth phase, organisms undergo aging followed by natural death.
Biodiversity
- Biodiversity encompasses the vast variety of life forms, from microscopic bacteria to massive blue whales.
- The term combines "bios" (life) from Greek and "diversity" (difference in forms) from English.
- A systematic classification of organisms is necessary due to the extensive diversity, facilitating the study of essential features of groups without needing to inspect every organism.
- Classification provides insights into relationships among different groups.
Systematics
- Systematics is the science examining the diversity of organisms and compares anatomy, morphology, biochemistry, and physiology to uncover evolutionary relationships.
- Often used interchangeably with taxonomy, systematics focuses on comparative groupings across classification levels.
Taxonomy
- Taxonomy, originating from Greek words "taxis" (arrangement) and "nomos" (law), deals with the identification, nomenclature, and classification of organisms.
- It encompasses the study of classification rules and practices:
- Systematic Botany: Taxonomy focused on plants.
- Systematic Zoology: Taxonomy focused on animals.
- Key figures in taxonomy:
- Carolus Linnaeus: Recognized as the father of taxonomy or systematic botany.
- H. Santapau: Acknowledged as the father of Indian taxonomy.
Types of Taxonomy
- α Taxonomy: Primarily considers morphological characteristics.
- β Taxonomy: Takes into account genetics, anatomy, physiology, and morphology.
- ω Taxonomy: Based on phylogenetic relationships among organisms.
