Cell Cycle and Cell Differentiation

Grade 8•45 minutes•3. Develop and use models to explain how events during the cell cycle lead to the formation of new cells and repair of multicellular organisms, including cell growth, DNA replication, separation of chromosomes, and separation of cell contents. a. Construct an explanation of the process of DNA replication during cellular division (S-phase). b. Using observations of cell growth, construct an explanation of how the cell cycle leads to differentiation in tissue development. Examples: stages of cellular differentiation that lead to formation of tissues in embryological development, dysfunction in the cell cycle that leads to uncontrolled cell growth (cancers and tumor growth), exposure to external stimuli that leads to changes in plant tissue growth or plant tropisms (phototropism, gravitropism)

Learning Objective

I can explain how the cell cycle leads to cell differentiation in tissue development, including examples of tissue formation during embryological development and uncontrolled cell growth.

Practice Questions

This lesson includes 10 practice questions to reinforce learning.

1. Explain the difference in differentiation potential between embryonic and adult stem cells, and where each type is found.

2. Describe how unspecialized embryonic stem cells change during cell differentiation to develop into cells with specific functions, like nerve or muscle cells.

3. How does the switching on or off of specific genes in a cell's DNA result in cell differentiation? Provide an example from the video.
