Study Notes
Characteristics of Living Things
- Living things display several key characteristics: nutrition, movement, growth, excretion, sensitivity, reproduction, respiration, and cellular structure.
- Nutrition involves the intake of substances for energy and growth.
- Movement refers to the ability to change position or location.
- Growth signifies an increase in size or mass over time.
- Excretion is the process of removing waste products from the body.
- Sensitivity indicates the ability to respond to environmental stimuli.
- Reproduction is the ability to produce offspring.
- Respiration is essential for generating energy needed for all biological processes.
- Living organisms are made up of cells, the fundamental unit of life.
Adaptability
- Adaptability encompasses the physical traits, behaviors, and life processes that enhance survival and reproduction in specific habitats.
- Organisms can change to fit their environment, illustrating evolution and the concept of natural selection.
Respiration
- Respiration is the biochemical process by which living organisms convert food into usable energy.
- This process is vital for maintaining life functions and overall vitality.
Hierarchy in Classification
- The classification of living things is organized in a hierarchical structure: domain, kingdom, phylum, class, order, family, genus, and species.
- This hierarchy helps categorize organisms based on shared characteristics and evolutionary relationships.
Binomial Nomenclature
- Binomial nomenclature is a formal system for naming species, consisting of two parts: the genus name and the species identifier.
- This system allows for standardized identification of organisms across different languages and regions.
Vertebrates
- Vertebrates are animals characterized by the presence of a backbone or spinal column.
- This group includes mammals, birds, reptiles, amphibians, and fish, and is distinguished from invertebrates, which lack a backbone.
