Mississippi Science BIO.1E

BIO.1E is a cluster heading. These are the individual standards under it.

• BIO.1E.1

  Construct models to explain how the processes of cell division and cell differentiation produce and maintain complex multicellular organisms.

• BIO.1E.2

  Identify and describe the changes that occur in a cell during the cell cycle. Explore problems that might occur if the cell does not progress through the cycle ...

• BIO.1E.3

  Relate the processes of cellular reproduction to asexual reproduction in simple organisms (i.e., budding, vegetative propagation, regeneration, binary fission)....

• BIO.1E.4

  Enrichment: Use scientific literature to investigate the role of stem cells in regeneration and asexual reproduction, and research applications of stem cells us...

01

What Students Need to Do

Students model how a cell grows, copies its DNA, separates chromosomes, and splits into two cells. They show how division and specialization build and repair tissues. They connect division to budding and binary fission and explain how failed controls can lead to cancer.

02

What Mastery Looks Like

A student traces one copied chromosome into each daughter cell and explains why both receive the same DNA as the parent. They explain how cells with matching DNA can become different cell types when different genes are active. They predict that a failed cell cycle check could allow uncontrolled growth.

03

Common Misconceptions

Students may think each daughter cell gets half the DNA because chromosomes split. They may think skin and nerve cells contain different DNA rather than using different genes. Some confuse normal repair with cancer or assume budding requires two parents.

04

How to Assess It

Exit ticket: Draw a skin stem cell copying DNA, dividing, and producing skin cells to cover a cut. Label why the daughter cells share DNA and where a failed check could lead to a tumor.

1. 01

   Have pairs duplicate each paper chromosome inside a yarn cell, then move one copy of each chromosome into each daughter cell.

2. 02

   Ask: If a skin cell and a nerve cell have the same DNA, why do they look and act differently?

3. 03

   Give groups shuffled cards labeled growth, DNA copying, chromosome separation, and cell splitting; race to order them and justify each placement.

4. 04

   Show photos of yeast buds and a healing scrape; ask students to identify where division forms offspring and where it repairs tissue.

• L.6.1.6

  Develop and use models to show relationships among the increasing complexity of multicellular organisms (cells, tissues, organs, organ systems, organisms) and h...

• BIO.3A

  Students will develop and use models to explain the role of meiosis in the production of haploid gametes required for sexual reproduction.

• L.6.1.3

  Develop and use models to explain how specific cellular components (cell wall, cell membrane, nucleus, chloroplast, vacuole, and mitochondria) function together...
