Study Notes

Introduction to Biology

Biology is the study of living organisms (bios = life, logos = study of)
Defining "life" is complex and there isn't a universally accepted definition.
Life can't be explained solely by chemical and physical laws.
Biology is a vast subject, divided into three main branches for study: Zoology (animals), Botany (plants), and Microbiology (microorganisms.)
Cell Biology, Histology, Anatomy, Physiology, Biochemistry, Genetics, and Ecology are some areas of study within these branches.

Issues Pertaining to Biology

Earth's biodiversity is extensive and includes 10-100 million species.
Life on Earth has evolved over billions of years.
The human body's structure and function are important aspects of biology.
Natural resources are crucial for human life.
Increased population and overuse are depleting natural resources
Environmental problems such as pollution and loss of biodiversity arise due to over-exploitation of natural resources.

Sustainable Food Production

Sufficient food production for a growing human population is essential using environmentally safe methods.
High-yielding varieties of plants/animals
Disease-resistant varieties of plants/animals
Improved post-harvest technology
Plant biology is vital for increased productivity and disease resistance.

Understanding Diseases

Knowledge of human diseases' causes and effects is crucial for maintaining health.
Non-communicable diseases (cancers, heart disease, diabetes) and communicable diseases (dengue, AIDS) are significant health concerns.
Further study is required into causes and cures for these issues.

The Nature & Organization of the Living World

Living organisms display diversity in size, shape, form and habitats.
Hierarchical levels of organization exist from molecules to biosphere.
Organisms order and organize in efficient ways starting from a molecular level.
Key characteristics of organisms include metabolism, growth & development, irritability/coordination, adaptation, reproduction, heredity and evolution.
