  /  Cellular Biology: Intro To Cell Structure

Objectives

  • Learn the definition of cell.
  • Know where the cell is found in the structural hierarchy of the human body.
  • Learn the difference between a prokaryotic and a eukaryotic cell.
  • Learn the basic organelles of a eukaryotic cell and their functions.
  • Understand how the organelles work together to make proteins

Description

The cell is fundamental to the living systems of biology. All organisms are made of cells. The cell is considered the basic unit of structure and function. Understanding cellular function is vital in understanding tissue, organ and body function. Many types of cells are interacting right now for you. In this lesson, students will be introduced to basic cell structure and function. Students will learn about the organelles in a cell that interact to keep it alive and making proteins. Class will include hands on interactions with cells and organelles and virtual field trip into a cell.

Sequence

  1. Introduction to the cell. Basic definition and description of cellular function.
  2. Discuss structural hierarchy within a cell (cell to tissue to organ to system to organism).
  3. Explain that cell is basic unit but not the smallest unit.
  4. Hands on activity - have students put IFXs in correct order from smallest to largest unit. Examples of what I used are include in the ancillary section
  5. Discuss prokaryotic vs eukaryotic cells.
  6. Have students look inside the cell that is in front of class. I put organelles inside of it.
  7. Identify the organelles and discuss functions of each.
  8. Discuss how they collectively are used to make proteins.
  9. Take field trip inside a cell. (website below in ancillary section)
  10. Come back to classroom and do wrap up activity. I compared the cell to a city. For this activity I created sticky notes that had a city job, Students matched sticky note up to the organelle it is describing. Example below in ancillary section.

Suggested Ancillary Support

IFXs I used for hands on activity: DNA to represent an organic compound, hemoglobin protein, nucleus, red blood cell, skin to represent tissue, heart, full body model to show both systems and a whole organism   360 Introduction to Cell Structure and Function: I turned sound off and talked about it myself. https://www.youtube.com/watch?v=PzxxEVdM1xI   Wrap up activity: nucleus: city hall ribosomes: city builders rough and smooth ER: factories Golgi body: post office vesicles: delivery trucks cytoplasm and cytoskeleton: highway system lysosomes: recycling/garbage disposal mitochondria: power plant cell membrane: city limits
