Comprehensive Guide to the Seven Characteristics of Living Organisms

Primary Characteristics of Living Organisms

  • Living things are defined by a specific set of biological parameters that distinguish them from non-living matter.
  • The notes identify these as the "Characteristis of living things" (noted with this specific spelling).
  • Mnemonic Identifier: The acronym provided to memorize these traits is "*MAS GREN".
  • Comprehensive Definition: The text states that "*MAS GREN IS the seven characteristics of organisms".

Movement

  • Fundamental Definition: Movement is described as an action performed by an organism or a specific part of an organism.
  • Physical Outcome: This action results in a perceptible change in the organism's "position or Place".

Respiration

  • Biological Definition: Respiration is defined as the complex of chemical reactions that take place within cells.
  • Functional Mechanism: These cellular reactions are responsible for breaking down nutrition molecules.
  • Energetic Purpose: The primary purpose of these reactions is to successfully "release energy".

Sensitivity

  • Core Concept: Sensitivity is characterized as the inherent ability of an organism to respond to environmental changes.
  • Internal Responses: The organism has the capacity to respond to the change within its own "internal environment".
  • External Responses: The organism also responds to changes occurring in the "external environment".

Growth

  • Nature of Growth: Growth is defined as a "permanent increase" in an organism.
  • Metrics of Increase: This permanent change is measured by an increase in:     * Total Physical Size.     * "Dry mass".
  • Cellular Drivers: The increase in size and mass is achieved through two distinct cellular pathways:     1. An increase in the total cell number.     2. An increase in the individual cell size.

Reproduction

  • Process Definition: Reproduction is identified as the biological process that facilitates the generation of offspring.
  • Species Continuity: The goal of this process is to make "more of the same kind of organism".

Excretion

  • Primary Function: Excretion is defined as the process of "removal" of substances from the body.
  • Substances Targeted for Removal:     * Waste products resulting from metabolism (cellular chemical processes).     * Any substance that exists in "excess of requirement".

Nutrition

  • Intake Mechanism: Nutrition is the process of "taking in of materials" into the organism.
  • Developmental Use: These materials are required and utilized specifically for the purposes of:     * Overall Growth.     * General Development.

Questions & Discussion

  • This section summarizes the provided marginalia and secondary notes found within the transcript.
  • Query/Aside: The text includes a notation regarding a chess-like move: "Leandt pawn to 2121".
  • Language Reference: There is a Thai phrase "ต่อเอาเองก" which translates roughly to "continue it yourself," followed by the character "ล".
  • Incomplete Fragments: The transcript includes the fragment "tics of of orga".

Document Metadata and Numerical Data

  • Page Numbering: The bottom of the first page is marked with the digit "11".
  • Header Labels: The documentation contains fields for "Memo No.", "Memo", and "Date".
  • Specific Date Sequence: A string of numbers and symbols is recorded under the Date field as 4×777774 \times 77777.
