Compare and Contrast Mitosis and Meiosis

  • Occurs in body cells

  • Occurs in sex cells

  • Produces 2 diploid daughter cells

  • Produces 4 haploid daughter cells

  • Daughter cells are genetically identical to parent cells

  • Daughter cells are genetically different from parent cells

  • Produces new cells

  • Undergo DNA replication

  • Starts with a diploid parent cell

  • Mitosis

  • Both

  • Meiosis

The process of cell modification from a generalized cell to one that performs a specific task is called:

Asemmisa {{asɛmmisaAhyɛnsode}}
3.

Cells of an undifferentiated type that are capable of becoming specialized are called:

Asemmisa {{asɛmmisaAhyɛnsode}}
4.

What type of organisms have differentiated cells?

Asemmisa {{asɛmmisaAhyɛnsode}}
5.

7.

What is the most essential element in bone marrow?

Asemmisa {{asɛmmisaAhyɛnsode}}
8.

If a cancerous mutation occurs in a stem cell in the bone marrow, what process does the stem cell go through that would cause the differentiated cells it produces to also be cancerous?

Consider:

How do mitosis and cell differentiation work together to produce and maintain a complex organism?

The rubric below shows point breakdown. Please be sure to include both of the roles - the role of mitosis and the role of cellular differentiation- in producing and maintaining complex organisms. Use the model to support your answer.
