Study Notes
Key Concepts in Biology
- Biology is the scientific study of life, encompassing various organisms and their interactions.
- Atoms are the smallest unit of matter, forming molecules through bonding.
Prokaryotes and Eukaryotes
- Prokaryotes include bacteria and archaea, characterized by the absence of a nucleus in their cells.
- Bacteria and archaea are the largest and most recognized groups among prokaryotes.
- Eukaryotes possess a nucleus and include organisms such as protists, fungi, plants, and animals.
Classification of Organisms
- Species refer to unique types of organisms, and populations are groups of interbreeding individuals of the same species in a defined area.
- Taxonomy is the classification system for organizing species based on shared characteristics.
Ecosystems and Biosphere
- The biosphere includes all regions of Earth that support life, consisting of various ecosystems.
- Ecosystems are communities of organisms interacting with their environment.
Cells and Tissues
- Cells are the smallest units of life, categorized into prokaryotic (without a nucleus) and eukaryotic (with a nucleus).
- Tissues are specialized cells organized to perform collective functions in multicellular organisms.
- Organs comprise groups of tissues working together for a specific task.
Scientific Method and Theory
- The scientific method involves systematic steps: observation, hypothesis formation, prediction, experimentation, data analysis, and conclusion.
- A scientific theory is a well-tested hypothesis that can make accurate predictions, whereas pseudoscience presents claims without adherence to scientific principles.
- Laws of nature describe consistent phenomena without complete explanations.
Characteristics of Living Organisms
- Life is defined by the capacity to reproduce, grow, and respond to stimuli.
- Biodiversity represents the variety of life on Earth and the importance of nutrients and energy for survival.
- Producers, such as plants, create their own food, while consumers obtain energy from other organisms.
Homeostasis
- Homeostasis refers to the maintenance of a stable internal environment in living organisms, essential for proper functioning and survival.
