Study Notes
Overview of Biology
- Study of living organisms and their interactions with each other and their environment
- Explores the structure, function, growth, evolution, and taxonomy of living things
Branches of Biology
- Botany: Study of plants, including their structure, growth, evolution, and classification
- Zoology: Study of animals, including their structure, behavior, and evolution
- Microbiology: Study of microorganisms, such as bacteria, viruses, and other microscopic life forms
- Ecology: Study of the interactions between organisms and their environment
- Genetics: Study of heredity, genes, and variation in organisms
- 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
Biological Molecules
- Carbohydrates: Provide energy for organisms (e.g., sugars, starches)
- Proteins: Perform various functions, such as enzymes, hormones, and structural components
- Lipids: Energy storage and structural components (e.g., fats, oils)
- Nucleic Acids: Contain genetic information (e.g., DNA, RNA)
Cell Structure and Function
- Cell Membrane: Regulates what enters and leaves the cell
- Cytoplasm: Gel-like substance inside the cell membrane where metabolic processes occur
- Nucleus: Contains genetic material (DNA)
- Mitochondria: Generate energy for the cell through cellular respiration
- Endoplasmic Reticulum: Involved in protein synthesis and transport
- Ribosomes: Site of protein synthesis
Biological Processes
- Photosynthesis: Process by which plants produce energy from sunlight
- Cellular Respiration: Process by which cells generate energy from glucose
- 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
Overview of Biology
- Encompasses the study of living organisms and their environmental interactions.
- Investigates structure, function, growth, evolution, and classification of life forms.
Branches of Biology
- Botany: Focuses on plants, covering aspects like structure, growth patterns, and classification methods.
- Zoology: Examines animal life, investigating their anatomical structure, behavior, and evolutionary trends.
- Microbiology: Delves into microorganisms, including bacteria and viruses, and their roles in ecosystems.
- Ecology: Studies relationships between organisms and their environments, highlighting food webs and ecosystem dynamics.
- Genetics: Explores heredity and variation through the study of genes and genetic principles.
- Biochemistry: Investigates chemical processes and substances that underpin biological functions in living organisms.
- Molecular Biology: Analyzes the interactions and functions of biological molecules like DNA and proteins.
Biological Molecules
- Carbohydrates: Serve as primary energy sources, including simple sugars and complex starches.
- Proteins: Critical molecules for various biological functions, acting as enzymes, hormones, and structural unit components.
- Lipids: Function in energy storage and cellular structure, encompassing fats, oils, and phospholipids.
- Nucleic Acids: Store and express genetic information; major examples are DNA and RNA.
Cell Structure and Function
- Cell Membrane: Controls entry and exit of substances, maintaining homeostasis.
- Cytoplasm: Medium where metabolic processes occur, housing organelles and cell components.
- Nucleus: Contains DNA, acting as the control center for genetic information.
- Mitochondria: Powerhouse of the cell, converting nutrients into usable energy via respiration.
- Endoplasmic Reticulum: Network for protein synthesis and intracellular transport; includes rough (with ribosomes) and smooth types.
- Ribosomes: Molecular machines that synthesize proteins from amino acids based on genetic instructions.
Biological Processes
- Photosynthesis: Plants convert sunlight into chemical energy, producing glucose and oxygen.
- Cellular Respiration: Cells transform glucose into energy, releasing carbon dioxide and water as byproducts.
- Mitosis: Form of cell division producing two genetically identical daughter cells for growth and repair.
- Meiosis: Specialized division leading to four non-identical gametes, crucial for sexual reproduction.
- Homeostasis: Mechanisms by which organisms regulate internal conditions, ensuring stability despite external fluctuations.
