Flashcards

Order in Living Organisms

The highly organized structure of living things, where atoms form molecules, molecules form organelles, organelles form cells, and cells form tissues, organs, organ systems, and ultimately organisms.

Sensitivity in Living Organisms

The ability of living organisms to react to changes in their environment. This can include responding to stimuli like light, temperature, food, or water.

Stimulus

A change in the environment that triggers a response in a living organism.

Response

The action of a living organism in response to a stimulus.

Study Notes

Characteristics of Living Organisms

  • Living organisms share key characteristics or functions
  • Order: Structures organized from atom to organism system

Sensitivity or Response to Environment

  • Organisms detect changes in their environment (e.g., cold, heat, food, water)
  • A response is a reaction to a stimulus
  • Example: Plants bend toward a light source. This is called phototropism.
    • Stimulus: light
    • Response: the plant bending
  • Another example: When you hear a noise, you turn your head in that direction
    • Stimulus: noise
    • Response: turning head
