Intro to Biology

Biology is the scientific study of life and living organisms, encompassing a vast range of topics from molecular biology to ecosystem ecology.
It examines the structure, function, growth, evolution, distribution, and taxonomy of all living things, including microorganisms, plants, animals, and humans, to understand the intricate relationships between them and their environments.

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 the relationships between organisms and their environment
Genetics: study of heredity, genes, and genetic variation
Biochemistry: study of the chemical processes that occur within living organisms
Molecular Biology: study of the structure and function of biological molecules, such as DNA and proteins

Molecules: basic building blocks of life, such as carbohydrates, proteins, and nucleic acids
Cells: basic structural and functional units of life
Tissues: groups of similar cells that perform a specific function
Organs: structures composed of two or more types of tissues that work together to perform a specific function
Organ Systems: groups of organs that work together to perform a specific function
Organism: individual living thing, such as a plant or animal
Population: group of organisms of the same species living in a specific area
Community: group of different species living in a specific area
Ecosystem: group of living and non-living components that interact in a specific area
Biosphere: all of the ecosystems on Earth

Carbohydrates: provide energy and structure for organisms
Proteins: perform a variety of functions, such as catalyzing reactions and replicating DNA
Nucleic Acids: contain the genetic information necessary for life
Lipids: provide energy and structure for organisms
ATP: molecule that provides energy for cellular processes

Cell Membrane: thin layer of lipid and protein molecules that surrounds the cell
Cytoplasm: jelly-like substance inside the cell membrane where metabolic processes occur
Nucleus: contains the cell's genetic material
Mitosis: process of cell division that results in two daughter cells with the same number of chromosomes as the parent cell
Meiosis: process of cell division that results in four daughter cells with half the number of chromosomes as the parent cell
