Branches of Biology

Branches of Biology

• Botany: study of plants, including their structure, growth, evolution, and classification
• Zoology: study of animals, including their structure, growth, evolution, and classification
• Microbiology: study of microorganisms, such as bacteria, viruses, and fungi
• Ecology: study of interactions between organisms and their environment
• Genetics: study of heredity, genes, and genetic variation
• Biochemistry: study of chemical processes within living organisms
• Biophysics: study of physical principles underlying biological processes
• Molecular Biology: study of biological molecules, such as DNA, proteins, and cells

Levels of Organization

• Molecule: basic building blocks of life, such as carbohydrates, proteins, and nucleic acids
• Cell: basic structural and functional unit of life
• Tissue: group of similar cells performing a specific function
• Organ: structure composed of two or more types of tissues performing a specific function
• Organ System: group of organs working together to perform a specific function
• Organism: individual living thing, such as an animal, plant, or microbe
• Population: group of organisms of the same species living in a specific area
• Community: group of different species living in a specific area
• Ecosystem: community of organisms and their physical environment

Biological Molecules

• Carbohydrates: energy-rich molecules, such as sugars and starches
• Proteins: molecules composed of amino acids, performing various functions in the body
• Nucleic Acids: molecules containing genetic information, such as DNA and RNA
• Lipids: molecules that do not dissolve in water, such as fats and oils

Cell Structure and Function

• Cell Membrane: thin layer of lipid and protein molecules surrounding the cell
• Cytoplasm: jelly-like substance inside the cell membrane, where metabolic processes occur
• Nucleus: membrane-bound organelle containing genetic material
• Mitochondria: organelles responsible for generating energy for the cell
• Endoplasmic Reticulum: network of membranous tubules and sacs involved in protein synthesis and transport
• Ribosomes: small organelles responsible for protein synthesis

Cellular Processes

• Photosynthesis: process by which plants convert light energy into chemical energy
• Cellular Respiration: process by which cells generate energy from glucose
• Mitosis: process of cell division resulting in two daughter cells with the same number of chromosomes as the parent cell
• Meiosis: process of cell division resulting in four daughter cells with half the number of chromosomes as the parent cell
