Study Notes
Properties of Life
- Characteristics of life include growth, reproduction, response to stimuli, and homeostasis.
- Not all entities exhibit these properties; for example, viruses do not fulfill all criteria of a living organism.
Adaptation and Evolution
- Organisms undergo adaptation to their environment through the process of evolution over many generations.
- Evolution is driven by natural selection, where favorable traits become more common in successive generations.
Biological Organization
- Biological levels of organization include both living (biosphere, ecosystem) and non-living components (abiotic factors).
- The highest level of biological organization discussed is the biosphere, encompassing all ecosystems on Earth.
Genetic Inheritance
- An organism's inherited DNA controls various traits and biological functions.
- Genes are the functional units of heredity that dictate the characteristics of organisms.
Study of Life
- The study of life from molecular levels to the entire ecosystem is called biology.
- This field explores life through various scales and contexts.
Cell Division
- Cells undergo mitosis during cell division, leading to the replication of genetic material and division into daughter cells.
Molecular Encoding
- DNA molecules are responsible for encoding the information necessary for building proteins through sequences of nucleotides.
Gene Expression
- The process of converting a gene's information into a functional cellular product, often a protein, is referred to as gene expression.
Protein Production
- In lens cells, the production of crystallin protein follows the sequence of transcription (DNA to mRNA) and translation (mRNA to protein).
Energy Transformation
- Living organisms typically convert solar energy into chemical energy through photosynthesis.
Energy Flow in Ecosystems
- Energy in an ecosystem flows from producers (like plants) to consumers (like animals) and decomposers, adhering to the laws of thermodynamics.
Emergent Properties
- Emergent properties in biology refer to characteristics that arise from the arrangement and interaction of components, not evident in individual parts.
Unity of Life
- All living organisms share underlying unity, including cellular structure, biochemical pathways, and genetic codes, reflecting common ancestry.
Structure and Function
- The correlation between structure and function in biology means that the form of a biological structure is closely related to its role and function within an organism.
Focus of Evolutionary Study
- The primary focus of evolution is to understand the mechanisms driving the diversity of life and the adaptation of organisms to their environments.
Biodiversity Studies Goals
- A key goal of biodiversity studies is to assess and conserve the variety of life forms and their interactions within ecosystems for ecological balance.
