Introduction to Biology

Biology is the scientific study of life and living organisms
It encompasses the structure, function, growth, evolution, distribution, and taxonomy of all living things

Botany: study of plants
Zoology: study of animals
Microbiology: study of microorganisms such as bacteria and viruses
Ecology: study of the interactions between organisms and their environment
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
Genetics: study of heredity and variation
Evolutionary Biology: study of the evolution of species over time

Molecule: basic building blocks of life (e.g. DNA, proteins, carbohydrates)
Cell: basic structural and functional unit of life
Tissue: group of similar cells that perform a specific function
Organ: structure composed of two or more types of tissues that perform a specific function
Organ System: group of organs that work together to perform a specific function
Organism: individual living thing (e.g. plant, animal, fungus)
Population: group of organisms of the same species that live in a specific area
Community: group of different species that live in a specific area
Ecosystem: community of organisms and their environment
Biosphere: all of the ecosystems on Earth

Photosynthesis: process by which plants convert light energy into chemical energy
Respiration: process by which cells convert glucose into energy
Mitosis: process of cell division that results in two identical daughter cells
Meiosis: process of cell division that results in four non-identical daughter cells (gametes)
Homeostasis: ability of an organism to maintain a stable internal environment despite changes in the external environment

Carbohydrates: energy-rich molecules (e.g. sugars, starches)
Proteins: molecules composed of amino acids that perform a variety of functions (e.g. enzymes, hormones, structural components)
Nucleic Acids: molecules that contain genetic information (e.g. DNA, RNA)
Lipids: molecules that perform a variety of functions (e.g. energy storage, cell membrane structure)
ATP (Adenosine Triphosphate): molecule that provides energy for cellular processes

Biology is the scientific study of life and living organisms, covering their structure, function, growth, evolution, distribution, and taxonomy.

Botany studies plants, while Zoology focuses on animals.
Microbiology explores microorganisms like bacteria and viruses.
Ecology examines the interactions between organisms and their environment.
Biochemistry delves into the chemical processes within living organisms.
Molecular Biology investigates the structure and function of biological molecules like DNA and proteins.
Genetics explores heredity and variation, while Evolutionary Biology examines the evolution of species over time.

Molecules, such as DNA and proteins, are the basic building blocks of life.
Cells are the basic structural and functional units of life.
Tissues consist of groups of similar cells performing specific functions.
Organs are composed of two or more types of tissues performing specific functions.
Organ Systems comprise groups of organs working together to perform specific functions.
Organisms are individual living things, such as plants, animals, or fungi.
Populations consist of groups of organisms of the same species living in a specific area.
Communities comprise groups of different species living in a specific area.
Ecosystems consist of communities of organisms and their environment.
The Biosphere encompasses all ecosystems on Earth.

Photosynthesis is the process by which plants convert light energy into chemical energy.
Respiration is the process by which cells convert glucose into energy.
Mitosis is the process of cell division resulting in two identical daughter cells.
Meiosis is the process of cell division resulting in four non-identical daughter cells (gametes).
Homeostasis is the ability of an organism to maintain a stable internal environment despite external changes.

Carbohydrates are energy-rich molecules, such as sugars and starches.
Proteins are composed of amino acids and perform various functions, including enzymes, hormones, and structural components.
Nucleic Acids, like DNA and RNA, contain genetic information.
Lipids perform various functions, including energy storage and cell membrane structure.
ATP (Adenosine Triphosphate) provides energy for cellular processes.

Founded in 1998 by Larry Page and Sergey Brin, initially named "Backrub" and later renamed to Google, inspired by the word "googol"
First office was set up in a friend's garage in Menlo Park, California
