Study Notes
Characteristics of Life
- All living organisms, from bacteria to frogs, share specific characteristics that define life.
- Characteristics include responsiveness to the environment, growth and development, reproduction, homeostasis, complex chemistry, and cellular structure.
Response to the Environment
- Living things detect environmental changes and react accordingly.
- Example: Turtles respond to threats by moving away; frogs may jump when approached.
Growth and Development
- Living organisms grow and develop; seeds transform into plants, and tadpoles change into adult frogs.
- Bacteria increase in size and volume as they grow.
Reproduction
- Living things reproduce to create offspring, utilizing either asexual or sexual reproduction.
- Asexual reproduction involves one parent (e.g., bacteria via binary fission), while sexual reproduction typically involves two parents leading to genetically diverse offspring.
Homeostasis
- All living organisms maintain a stable internal environment despite external changes.
- Humans regulate body temperature; frogs might alter skin color in response to temperature fluctuations.
Complex Chemistry
- Living organisms comprise large, complex molecules and engage in numerous chemical reactions necessary for life.
- Metabolism refers to all biochemical reactions within a cell or organism, requiring a continuous energy supply.
Cellular Structure
- All living things consist of at least one cell, which is fundamental to structure and function.
- Cells, although appearing diverse externally, share similarities at a microscopic level; they can be unicellular (like bacteria) or multicellular (like frogs, which can have trillions of cells).
