B1.1 Characteristics Of Living Organisms

Living vs non-living: key idea

• Bio - life; Logy - study

• the word organisms is used to mean living things, and that saying “living organism” can be redundant.

• All organisms have 7 traits

• They provide a framework to identify life and distinguish living organisms from dead matter or inanimate objects.

• Examples like phototropism (movement toward light) illustrate how organisms interact with their environment to meet energetic and metabolic needs.

  • nutrition

  • respiration

  • sensitivity

  • growth

  • reproduction

  • excretion

  • nutrition

Examples and concepts mentioned in the transcript

• Toward the sunlight to maximize photosynthesis

  • This is presented as a directional response to the environment (a form of movement toward a stimulus) aimed at optimizing energy capture for metabolism.

• Sensitivity (response to environment)

  • Defined as the ability to sense the environment and respond to it.

  • The transcript mentions eyes and light detection to illustrate how organisms sense stimuli, emphasizing that sensing light is part of responding to the environment.
