Exploring the Nucleus: The Control Center of Eukaryotic Cells
Slide 1 - Tekstslide
Learning Objectives
At the end of the lesson you will understand the structure and function of the nucleus, its components, and its role in cellular processes.
Slide 2 - Tekstslide
What do you already know about the nucleus and its functions in cells?
Slide 3 - Woordweb
Introduction to the Nucleus
The nucleus is the control center of eukaryotic cells, housing genetic material. It regulates cellular functions and maintains cellular integrity.
Slide 4 - Tekstslide
The Nuclear Envelope
The nuclear envelope is a double membrane that separates the nucleus from the cytoplasm, maintaining a distinct nuclear environment.
Slide 5 - Tekstslide
Nuclear Pores and Transport
Nuclear pores are gateways for molecular traffic. They regulate active and passive transport between the nucleus and cytoplasm.
Slide 6 - Tekstslide
Understanding Nucleoplasm
Nucleoplasm, or nuclear sap, is the substance within the nucleus, supporting chromatin and the nucleolus.
Slide 7 - Tekstslide
Chromatin: Structure & Function
Chromatin is DNA wrapped around proteins. Euchromatin is active; heterochromatin is inactive, crucial for gene expression and DNA replication.
Slide 8 - Tekstslide
The Nucleolus
The nucleolus is a dense region for ribosome biogenesis, playing a key role in protein synthesis and cellular metabolism.
Slide 9 - Tekstslide
Nuclear Lamina
The nuclear lamina, composed of lamin proteins, maintains nuclear shape and supports DNA replication and cell division.
Slide 10 - Tekstslide
Nucleus in the Cell Cycle
The nucleus regulates the cell cycle phases: interphase, mitosis, and cytokinesis, with structural changes throughout.
Slide 11 - Tekstslide
Write down 2 things you want to know more about.
Slide 12 - Open vraag
Write down 3 things you learned in this lesson.
Slide 13 - Open vraag
Ask 1 question about something you haven't quite understood yet.
Slide 14 - Open vraag
