SC15.7.3

Construct an explanation of the function (e.g., mitochondria releasing energy during cellular respiration) of specific cell structures (i.e., nucleus, cell membrane, cell wall, ribosomes, mitochondria, chloroplasts, and vacuoles) for maintaining a stable environment.

Structure and Function

Knowledge

Students know:
  • Function of organelles (i.e., nucleus, cell membrane, cell wall, ribosome, mitochondria, chloroplast, vacuole).
  • Roles of organelles in maintaining a stable environment.
  • Key differences between animal and plant cells (e.g., Plant cells have a cell wall, chloroplasts, etc.).

Skills

Students are able to:
  • Articulate a statement that relates a given phenomenon to a scientific idea, including how different parts of a cell contribute to how the cell functions as a whole, both separately and together with other structures.

Understanding

Students understand that:
  • The function of an organelle contributes to the overall function of the cell, both separately and together with other organelles, to maintain a stable environment.
  • Organelles function together as parts of a system (the cell).
  • Organelles function together as parts of a system that determines cellular function.
  • Energy is required to maintain a stable environment.
