Mississippi Science BIO.1E.1
The Standard
- BIO.1E
- Students will develop and use models to explain the role of the cell cycle during growth, development, and maintenance in multicellular organisms.
Construct models to explain how the processes of cell division and cell differentiation produce and maintain complex multicellular organisms.

What This Standard Means
What Students Need to Do
- Students build a model showing how cell division makes more cells and differentiation gives cells different jobs. They use it to explain growth and how tissues replace damaged cells.
What Mastery Looks Like
- A student can trace skin and muscle cells back to one starting cell. Their model labels division and specialization separately and shows new skin cells replacing damaged ones.
Common Misconceptions
- Students may think division automatically changes a cell's job, or that skin and muscle cells have different DNA. Some think division stops once an organism finishes growing.
How to Assess It
- Exit ticket: Draw a model from one fertilized egg to skin and muscle cells. Label where cells divide and specialize, then show how damaged skin is replaced.
Lesson moves
Ways to Teach It
Use paper cell cutouts to build a branching model of repeated divisions, then color groups as skin and muscle cells and label their jobs.
Ask, 'If skin and muscle cells carry the same DNA, why do they do different jobs?' Have students answer using gene activity.
Give pairs three flawed diagrams showing changed DNA, only one cell type, or no cell replacement; have them correct and relabel each.
Show a photo of a healing scrape; ask students to sketch dividing skin cells and explain how they replace damaged cells.
