College of San Mateo Cell Organelle Plan Paper

Cell Organelle Assignment

Lesson Plan Outline: Human body with 30 to 40 trillion diverse (200 types) cells (plus equal number of resident microbes) organized in simple to complex levels (chemical, cellular, organ, organ system, organism) can be an excellent resource to make a connection at multilevel of hierarchy and interconnectedness.
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

The three tenets to the original cell theory were:

1. All living organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. Cells arise from pre-existing cells.

The generally accepted tenets of modern cell theory include:

1. All known living things are made up of one or more cells
2. All living cells arise from pre-existing cells by division.
3. The cell is the fundamental unit of structure and function in all living organisms.
4. The activity of an organism depends on the total activity of independent cells.
5. Energy flow (metabolism) occurs within cells.
6. Cells contain Deoxyribonucleic Acid (DNA) which is found specifically in the chromosomes and Ribonucleic Acid (RNA) found in the cell nucleus and cytoplasm.
7. All cells are basically the same in chemical composition in organisms of similar species.

An analogy is a similarity between concepts. Analogies can help students build conceptual bridges between what is familiar and what is new. Often, new concepts represent complex, hard-to-visualize systems with interacting parts.
Analogies can serve as early “mental models” that students can use to form limited but meaningful understandings of complex concepts. Analogies can play an important role in helping students construct their own knowledge, a process that is encouraged in the Standards and consistent with a constructivist view of learning. As students’ develop cognitively and learn more science, they will evolve beyond these simple analogies, adopting more sophisticated and powerful mental models.
Assignment:
Fill in the chart below while reading information at the Cells: A Busy Factory site. In the second column of the chart, write the name of the organelle that functions most like the factory worker described in the first column. In the third column, write a brief description of the function of the organelle in the cell.
The product of the factory is PROTEIN.
