Characteristics of Living Things
Characteristics of Living Things
Biology Biology is the study of life, so we are only interested in things that are living. It sounds silly, but we must define what characteristics are needed to determine if something is living or nonliving Living things must contain ALL of the characteristics, if they are missing one or more, they are considered nonliving
Living things must… 1) Be made of Cells – Smallest level that is living
Living Things must… 2) Be able to maintain their internal conditions which is called Homeostasis.
Living things must… 3) Be able to Reproduce Two Types: Asexual (Clones) – Only one parent Sexual – Two parents
Living things must… 4) Have complex Organization
13 Levels of Organization Atom (Smallest) Molecule (Biomolecule) Organelle Cell (1st Level that is LIVING) Tissue Organ Organ System Organism Population Community Ecosystem Biome Biosphere (Largest)
Living things must… 5) Be able to Metabolize Metabolism – a sum of all chemical reactions in the body that maintain life; Building up or breaking down of molecules.
Living things must… 6) Obtain and use Energy - Energy is conserved; it can be transformed. Examples: solar energy, chemical energy, cellular energy (ATP)
Living things must… Be able to 7) Develop and 10) Grow
Living things must…. 10) Growth - To increase in number and/or size Development - Dramatic change in form (i.e. metamorphosis - caterpillarbutterfly; tadpole frog)
Living things must… 8) Be able to Respond to Stimuli or the Environment (to maintain homeostasis) - Reacting to internal signals or signals from the environment
Living things must… 9) Adapt to their environment and develop adaptations Adaptation – Any characteristic (structure, function, behavior) that increases the chance for survival; it must be encoded in the DNA
Living things must… Be able to Adapt to the Surroundings or Environment – Any characteristic (structure, function or behavior) that increases the chance for survival; it must be encoded in the DNA.
Living Things Must…. 11) Contain Genetic Material – DNA and RNA.
