Study Notes
Reproduction and Growth
- In most higher animals and plants, reproduction and growth occur inside the body.
- Reproduction is not synonymous with growth because non-living organisms can also reproduce.
- Growth includes the increase in mass and number of individuals, particularly in unicellular and multicellular organisms.
Metabolism
- Metabolism is the sum total of all chemical reactions occurring in the body.
- Catabolism refers to the breakdown processes, while anabolism refers to the synthesis processes.
- Certain simple molecules form part of metabolic reactions.
Characteristics of Living Organisms
- Defining characteristics include growth, reproduction, metabolism, and responding to stimuli.
- Not all living processes result from underlying interactions, indicating complexity in biological functions.
- Organisms can be categorized based on their ability to sense their environment (prokaryotes and eukaryotes).
Fragmentation and Reproduction
- Fragmentation is a method of reproduction observed in certain organisms.
Taxonomy
- Taxonomic studies are important in agriculture, forestry, and understanding biodiversity.
- Taxonomy involves identification, nomenclature, and classification of organisms.
- The scientific term for a category in taxonomy is "taxon."
- Binomial nomenclature, a system for naming organisms, was developed by Linnaeus.
Growth Dynamics
- Growth occurs continuously in both plants and animals, but may vary in timing and duration.
- Extrinsic and intrinsic growth factors influence organisms, distinguishing between controlled and uncontrolled growth.
Key Terminology
- Eukaryotes are capable of sensing and responding to environmental cues, while prokaryotes can too.
- Homeostasis entails maintaining internal stability, a crucial aspect of living organisms.
