| Subject: Biology |
| Lesson Topic: recognise organelles and other cell structures found in eukaryotic cells and outline their structures and functions, limited to: cell surface membrane, nucleus, nuclear envelope and nucleolus, rough endoplasmic reticulum, smooth endoplasmic reticulum |
Learning Objective/s:
- Identify the cell surface membrane, nucleus (including envelope and nucleolus), rough ER and smooth ER in labelled diagrams.
- Describe the key structural features of each of these organelles.
- Explain the primary functions of each organelle within a eukaryotic cell.
- Compare the roles of rough and smooth endoplasmic reticulum.
- Apply knowledge to predict the cellular impact of a dysfunction in any of these organelles.
|
Materials Needed:
- Projector and screen
- PowerPoint slides showing organelle diagrams
- Printed handouts of the organelle comparison table
- Whiteboard and markers
- Index cards for quick‑fire quiz
- Sticky notes for exit tickets
|
Introduction:
Begin with a short video of a cell “factory” to capture interest. Ask students what structures they think act as the “walls”, “control centre” and “assembly lines”. Link this to their prior knowledge of the cell membrane from the previous lesson and outline today’s success criteria: students will be able to recognise, describe and explain the five target organelles.
|
Lesson Structure:
- Do‑now (5'): Students label a blank eukaryotic cell diagram and submit.
- Mini‑lecture with slides (10'): Overview of the cell surface membrane, nucleus (envelope & nucleolus), rough ER and smooth ER.
- Group activity – organelle card poster (10'): Teams place organelle cards on a large cell poster, noting structural features.
- Guided inquiry (10'): Complete a comparison table for RER vs SER, discussing protein vs lipid synthesis.
- Formative check – Kahoot/quiz using index cards (5'): Quick recall of functions.
- Recap & exit ticket (5'): Write one function of each organelle on a sticky note and hand in.
|
Conclusion:
Summarise the key structures and functions covered, highlighting how each organelle contributes to overall cell operation. Collect exit tickets as a retrieval check and assign a worksheet that asks students to extend their knowledge to additional organelles for homework.
