Part 1: The Cell – Structure and Function

This section explores the basic building block of life – the cell. It digs into the various organelles within the cell and their specific functions.

1. Identifying Cell Structures:

• Cell Membrane (Plasma Membrane): The outer boundary of the cell, responsible for regulating the passage of substances in and out. Think of it as the cell's gatekeeper.
  • Coloring: Typically colored in a distinct color (e.g., blue) to represent its barrier function.
• Nucleus: The control center of the cell, containing the genetic material (DNA).
  • Coloring: Often colored a prominent color (e.g., purple) to signify its importance.
• Cytoplasm: The gel-like substance within the cell membrane that houses the organelles.
  • Coloring: Usually colored a neutral color (e.g., light yellow) to provide a background.
• Endoplasmic Reticulum (ER): A network of membranes involved in protein and lipid synthesis.
  • Rough ER: Studded with ribosomes, involved in protein synthesis.
    • Coloring: Differentiated from smooth ER by adding small dots (representing ribosomes) and coloring differently (e.g., light green).

    • Coloring: Water molecules colored blue and arrows showing the direction of water movement.
• Active Transport: Requires energy (ATP) to move substances against their concentration gradient. Includes:
  • Sodium-Potassium Pump: Moves sodium ions out of the cell and potassium ions into the cell.
    • Coloring: Sodium ions colored orange, potassium ions colored purple, and the pump protein colored a distinct color (e.g., gray), with an indication of ATP usage.

  • S Phase: DNA replication.
  • G2 Phase: Preparation for mitosis.
  • Coloring: Each phase colored a different color to distinguish them.
• Mitosis: The process of nuclear division, resulting in two identical daughter cells. Consists of prophase, metaphase, anaphase, and telophase.
  • Prophase: Chromosomes condense and become visible.
    • Coloring: Chromosomes colored a distinct color (e.g., red) and becoming visible.
  • Metaphase: Chromosomes align along the metaphase plate.
    • Coloring: Chromosomes aligned in the middle of the cell.
