Introduction
Nucleus is membrane-enclosed organelle found in eukaryotic cells, contains cell’s genetic material
Pre-Requisites:
Understanding the fact that cell have organelles to perform various functions
Activity:
Cheek cells under the microscope
Real Life Question:
How does the information of inheritance of cell passed on to next generation? How does cell development determined?
