Properties of Life

What characteristics do living creatures have in common?

characteristics of living things
Characteristics of Living Things
  • All living things:
    • have an orderly structure
    • produce offspring
    • grow and develop
    • adjust to changes in the environment
    • Use energy
    • Adapt to their environment
living creatures are organized
Living creatures are ORGANIZED
  • All made of the same collection of chemicals, but we are organized as…
    • molecules
      • proteins, fats, carbohydrates, nucleic acids

carbohydrates

proteins

DNA

living things are organized
Living things are organized

orderly structure: (one or more cells)

~ cell- smallest unit of life

~tissue- group of cells that perform a common function

~organ- group of tissue that perform a common function

~organ system- a group of organs that perform a common function

~organism- any complete living thing

living creatures are organized1
Living creatures are ORGANIZED
  • All made of the same collection of chemicals, but we are organized as…
    • organelles & cells
      • plant cells & animal cells

plant cell

Living creatures are ORGANIZED
  • All made of the same collection of chemicals, but we are organized as…
    • organs & organ systems
      • respiratory, circulatory, digestive, etc.
living creatures reproduce
Living creatures REPRODUCE
  • Make the next generation
living things make more living things
Living things make more living things
  • Reproduction~ the production of offspring.
  • (necessary for species *to survive; not necessary for individual organism’s survival)
  • 2 types:
    • 1. asexual: 1 parent: offspring identical to parent
    • 2. sexual: 2 parents, offspring not identical to parents
  • * A species is a group of organisms that can interbreed and produce fertile offspring in nature
living things change during their lives
Living things change during their lives
  • Growth results in an increase in the amount of living material and the formation of new structures.(cell division)
  • All of the changes that take place during the life of an organism are known as its development.
living things adjust to their surroundings
Living things adjust to their surroundings
  • Anything in an organism’s external or internal environment that causes the organism to react is a stimulus
  • A reaction to a stimulus is a response.
living creatures respond
Living creatures RESPOND
  • Respond to internal changes
    • Homeostasis
      • maintaining balanced conditions inside the body
  • Respond to external changes
living things adjust to their surroundings1
Living things adjust to their surroundings
  • Regulation of an organism’s internal environment to maintain conditions suitable for its survival is called homeostasis
living creatures use energy
Living creatures use ENERGY
  • Metabolism
    • all the reactions your body performs to make & use energy
      • eating & digestion & elimination of waste
      • synthesis = building
      • cellular respiration = making energy

mitochondria

living things adapt and evolve
Living things adapt and evolve
  • Any structure, behavior, or internal process that enables an organism to respond to environmental factors and live to produce offspring is called an adaptation
  • Adaptations are inherited from previous generations.
  • The gradual change in a species through adaptations over time is evolution.
