Biology Basics Quiz

Definition and Scope

• Biology is the scientific study of life and living organisms
• Examines the structure, function, growth, evolution, distribution, and taxonomy of all living things
• Encompasses various disciplines, including botany, zoology, microbiology, ecology, and biochemistry

Branches of Biology

• Botany: study of plants and plant-like organisms
• Zoology: study of animals and animal-like organisms
• Microbiology: study of microorganisms, such as bacteria and viruses
• Ecology: study of interactions between organisms and their environment
• Biochemistry: study of chemical processes and substances in living organisms
• Molecular Biology: study of structure, function, and interactions of biomolecules
• Genetics: study of heredity and variation in organisms
• Evolutionary Biology: study of evolution and diversity of life on Earth

Major Concepts

• Cells: basic unit of life, consisting of cell membrane, cytoplasm, and genetic material
• DNA (Deoxyribonucleic acid): molecule containing genetic instructions for development and function
• Genetics: study of how traits are inherited and expressed
• Evolution: change in species over time through natural selection, mutation, and genetic drift
• Ecosystems: interactions between living organisms and their environment
• Homeostasis: ability of organisms to maintain internal balance and stability
• Biodiversity: variety of species, ecosystems, and genes on Earth

Biological Molecules

• Carbohydrates: energy-rich molecules, such as sugars and starches
• Proteins: biomolecules with structural, functional, and regulatory roles
• Lipids: energy-rich molecules, such as fats and oils
• Nucleic Acids: DNA and RNA, containing genetic information
• ATP (Adenosine Triphosphate): energy currency of cells

Biological Processes

• Metabolism: conversion of energy and nutrients into cellular components
• Photosynthesis: process by which plants convert light energy into chemical energy
• Respiration: process by which cells generate energy from nutrients
• Cell Division: process of cell growth, reproduction, and repair
• DNA Replication: process of duplicating genetic material
• Gene Expression: process of translating genetic code into proteins
