Study Notes
Overview of Biology
- Biology derives from the Greek words "bios" (life) and "logus" (study), representing a systematic body of knowledge based on truth and facts.
- It focuses on the investigation, classification, structure, and relationships of living things, utilizing experimentation to explain observations.
Branches of Science
-
Natural Science (NS):
- Involves understanding and describing nature, including the study of both living (Biological Science) and non-living (Physical Science) phenomena.
-
Physical Science:
- Examines non-living elements; includes fields such as Physics, Chemistry, and Earth Science.
-
Biological Science:
- Concerns the study of living organisms, such as Biology and Genetics.
-
Social Science (SS):
- Studies human behavior and societal aspects including Politics, Economics, History, and Geography.
-
Applied Science (AS):
- Practical applications of theoretical science, covering areas like Medicine, Engineering, Nursing, and Architecture.
Branches of Biology
- Ecology: Interaction among organisms and their environment.
- Genetics: Heredity and transmission of traits from parents to offspring.
- Evolutionary Biology: Changes in organisms over time.
- Cytology: Study of cells.
- Histology: Study of tissues.
- Anatomy: Structure of body parts.
- Physiology: Functions of body parts.
- Pathology: Study of diseases.
- Taxonomy: Classification of living organisms.
- Botany: Structure and functions of plants.
- Zoology: Structure and functions of animals.
- Microbiology: Study of microorganisms.
- Parasitology: Study of parasites.
- Phycology: Study of algae.
- Mycology: Study of fungi.
Levels of Biological Organization
- Life is organized hierarchically from small to large:
- Cell → Tissue → Organ → Organ System → Organism → Population → Community → Ecosystem.
Cells and Tissues
-
Cell:
- Basic unit of life, composed of living matter enclosed by a barrier.
-
Types of Cells:
- Sex Cells: Found in reproductive organs (spermatozoa - male gametes, ova/ovum - female gametes).
- Blood Cells: Produced in bone marrow.
-
Tissue:
- Groups of similar cells that perform specific functions.
-
Types of Tissues:
- Connective Tissue: Binds and supports, e.g., bones.
- Epithelial Tissue: Covers surfaces, e.g., skin.
-
Muscle Tissue: Facilitates movement; includes:
- Smooth (internal organs)
- Cardiac (heart)
- Skeletal (muscles connected to the skeleton)
- Nervous Tissue: Composed of nerve cells (neurons), primarily found in the brain.
Organs
- Groups of tissues that work collectively to perform closely related functions, e.g., liver, kidney, heart, and lungs.
