Overview:

The students will identify, describe and discuss the function of the various cellular organelles (nucleus, smooth and rough endoplasmic reticulum, Golgi apparatus, etc.) and their functions by drawing the cell with the organelles included and then discussing them with others in the class.

This activity is a result of the ALEX Resource Development Summit.

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.


NAEP Framework
NAEP Statement::
L8.1b: All organisms are composed of cells, from one cell only to many cells. About two-thirds of the weight of cells is accounted for by water, which gives cells many of their properties. In multicellular organisms, specialized cells perform specialized functions. Organs and organ systems are composed of cells and function to serve the needs of cells for food, air, and waste removal. The way in which cells function is similar in all living organisms.

Knowledge:
Students know:

  • Key differences between animal and plant cells (e.g., Plant cells have a cell wall, chloroplasts, etc.).
Skills:
Students are able to:

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.

2 ) Obtain, evaluate, and communicate information to describe the function and diversity of organelles and structures in various types of cells (e.g., muscle cells having a large amount of mitochondria, plasmids in bacteria, chloroplasts in plant cells).


NAEP Framework
NAEP Statement::
L12.3: Cellular processes are regulated both internally and externally by environments in which cells exist, including local environments that lead to cell differentiation during the development of multicellular organisms. During the development of complex multicellular organisms, cell differentiation is regulated through the expression of different genes.

Knowledge:
Students know:
  • Historical contributions to the cell theory by scientists such as Hooke, Leeuwenhoek, Schleiden etc.
  • The cell theory is one of the fundamental ideas of modern biology and includes three principles:
    1. All living things are composed of cells.
    2. Cells are the basic unit of structure and organization of all living organisms.
    3. Cells arise only from previously existing cells.
  • There are many types of organelles.
  • Eukaryotic cells contain a nucleus and other membrane bound organelles.
  • Prokaryotic cells are cells without a nucleus or other membrane bound organelles.

  • Communicate information to describe the function of organelles and cell structures in various types of cells.
  • Communicate information to describe the diversity of organelles and structures in various types of cells.
Understanding:
Students understand that:
  • Structures within different types of cells will have different functions.
  • Cellular function is related to the presence and number of particular organelles and cell structures.

Learning Objectives:

The students will be able to identify the cellular organelles, define their functions and discuss these with other students in the classroom.

  Strategies, Preparations and Variations  
Phase:
After/Explain/Elaborate
Activity:

Students will draw the assigned organelle, such as the nucleus, smooth endoplasmic reticulum, Golgi apparatus, etc., on the desktop or tabletop with neon markers.  They will label all parts of the organelle and write the function of the organelle as well.  After the students are finished, they will present their organelle to the class. The students will need to explain the organelle and its function to the class.  The presentations can be done as a walkabout or as a classroom presentation.

Assessment Strategies:

The teacher will walk around the classroom while the students are working to make sure that all students can identify their assigned organelle, describe their assigned organelle, and discuss its functions.  The teacher will also be able to assess student understanding during the presentations of the organelles.


Advanced Preparation:

The students will need to know the cellular organelles and their functions before completing this activity.  

The teacher needs to gather neon markers for the student drawings.  

Variation Tips (optional):

The teacher may use butcher paper and regular markers or chalk markers if neon markers are not available.  The teacher may also display a diagram of the cell containing all of the organelles for reference.  This activity may be used as an explore/explain/during activity.  If using this activity for Explore/Explain/During, the teacher will need to provide a method for students to research their assigned organelle.
