EOU Exam on Thursday, May 1st

Lesson #9: Monster Tumors

Cell Differentiation / Specialization

Learning Intention:

Students will be able to identify how genetically identical cells can have different structures and functions in order to explain the phenomenon of teratoma tumors.

Success Criteria:

I am successful when I can...

1. Discuss a real-world example (teratoma) that shows how cells in the human body look and function differently, even though they contain identical DNA.

2. Explore by investigating evidence that specialized cells, such as muscle cells and nerve cells, activate different genes despite sharing the same genetic material.

3. Explain the process of cell differentiation, emphasizing that gene activation leads genetically identical cells to develop unique structures and functions.

4. Apply my understanding of cell differentiation to predict how the activation or deactivation of specific genes affects a cell’s structure and role within an organism.

5. Evaluate data or models to determine if specialized cells have activated or deactivated certain genes, supporting my conclusions with scientific reasoning.

Reminders:

1) Parent teacher conference March 20th and 21st.

2) End of Unit exam this Thursday. March 13th.

Our Story

A resident in East Valley, Ohio went to the emergency room with a pain near her hip / pelvis. Doctor's took an MRI and discovered that the woman had a tumor the size of a lemon growing on her right ovary. Doctors scheduled her for surgery right away and removed the tumor from her ovary. To their surprise, the tumor had hair, teeth and was even beginning to develop an eye!

This type of tumor is a called a Teratoma.

Turn n' Talk:

1) If all our cells are made genetically identical through mitosis, why do they look so different and have specific jobs? ➡️

2) How could teeth, hair and eye cells be growing where ovary cells are supposed to be?

Part 5:

Stop n' Jot

Differentiation = Specialization: Differentiation is the process during development where newly formed cells become specialized.

All cells of an organism share identical genes – each cell contains the entire set of genetic instructions for that organism.
The activation of different genes by chemical signals will cause it to differentiate.
