Branches of Biology Quiz

Branches of Biology

• Botany: study of plants
• Zoology: study of animals
• Microbiology: study of microorganisms (bacteria, viruses, etc.)
• Ecology: study of interactions between organisms and their environment
• Biochemistry: study of chemical processes within living organisms
• Molecular Biology: study of biological molecules and their interactions

Cells

• Cell Theory: all living organisms are composed of cells, cells are the basic unit of life, and all cells come from pre-existing cells
• Cell Structure: cell membrane, cytoplasm, nucleus, mitochondria, ribosomes, lysosomes
• Cell Functions: metabolism, growth, reproduction, response to stimuli, maintenance of homeostasis

Genetics

• Mendelian Genetics: study of inheritance patterns of traits based on Mendel's laws
• DNA Structure: double helix model, nucleotides (A, C, G, T), genes, chromosomes
• Genetic Code: sequence of nucleotides determines amino acid sequence of proteins
• Genetic Variation: mutations, genetic recombination, gene expression

Evolution

• Theory of Evolution: species change over time through natural selection, genetic drift, mutation, and gene flow
• Natural Selection: process by which individuals with favorable traits are more likely to survive and reproduce
• Species: group of organisms that can interbreed and produce fertile offspring
• Fossil Record: chronological record of evolution through fossil evidence

Ecosystems

• Ecosystem: community of living organisms and their physical environment
• Food Chain: sequence of organisms that eat other organisms for energy
• Food Web: network of food chains
• Energy Flow: energy from sunlight is transferred from one organism to another through food chains and webs
• Nutrient Cycling: nutrients are recycled through ecosystems through decomposition and nutrient uptake

Branches of Biology

• Botany is the study of plants
• Zoology is the study of animals
• Microbiology is the study of microorganisms, including bacteria and viruses
• Ecology is the study of interactions between organisms and their environment
• Biochemistry is the study of chemical processes within living organisms
• Molecular Biology is the study of biological molecules and their interactions

Cells

• The cell theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells come from pre-existing cells
• A cell consists of a cell membrane, cytoplasm, nucleus, mitochondria, ribosomes, and lysosomes
• Cell functions include metabolism, growth, reproduction, response to stimuli, and maintenance of homeostasis

Genetics

• Mendelian Genetics studies the inheritance patterns of traits based on Mendel's laws
• DNA has a double helix structure, consisting of nucleotides (A, C, G, T), genes, and chromosomes
• The genetic code determines the sequence of nucleotides that specifies the amino acid sequence of proteins
• Genetic variation occurs through mutations, genetic recombination, and gene expression

Evolution

• The theory of evolution states that species change over time through natural selection, genetic drift, mutation, and gene flow
• Natural selection is the process by which individuals with favorable traits are more likely to survive and reproduce
• A species is a group of organisms that can interbreed and produce fertile offspring
• The fossil record provides a chronological record of evolution through fossil evidence

Ecosystems

• An ecosystem is a community of living organisms and their physical environment
• A food chain is a sequence of organisms that eat other organisms for energy
• A food web is a network of food chains
• Energy flows from one organism to another through food chains and webs, originating from sunlight
• Nutrient cycling occurs through decomposition and nutrient uptake, recycling nutrients through ecosystems
