Eukaryotic Cell Ultrastructure

Learning activities to help students draw cell diagrams

This activity contains a full set of resources for teaching about the structure of eukaryotic cells. There is a student activity sheet, with examiner's hints, a short screencast explaining how to draw a eukaryotic cells (liver cell), flashcards to help students' learn the ultrastructure labels, a quick test of the labels and IB style questions, with answers.


Lesson Description

Guiding Questions

What are the different structures in a eukaryote cell?

Imagine a cell to be like a school and the organelles are the classrooms. Why is it an advantage to have all the biology resources in the biology lab?

Why is it an advantage to keep all the enzymes for respiration in a mitochondrion?

Activity 1: What does a Eukaryote cell look like?

Open this TEM image of a liver cell

  1. Click the plus and minus to change the magnification from 5000x to 86000x.
  2. Drag the red box to move to other parts of the cell
  3. Can you identify the following organelles: (use a text book for help)
    1. Nucleus
    2. Nuclear membrane
    3. Mitochondria
    4. Ribosomes
    5. Rough endoplasmic reticulum
    6. Plasma membrane

Extension ideas

You could measure the scale bar and determine the magnification of some images.

Look at this Example of a great student project on eukaryote cells - could you do one like it?

Activity 2: Organelles and their functions

Matching pairs game

Print the Organelle flash cards Fold the page along the dotted line, glue together then cut the solid horizontal lines to make cards.

  • One student places the cards on the table with the organelle names showing.
  • Their partner uses their set of flashcards to read out a function at random.
  • The student chooses the best card for that function and checks their answer.
  • If the answer is correct the two cards are placed together on the table.
  • Gradually pairs of cards are collected.

After 5 minutes students swap roles and play again.


For further practice - or if students have access to computer the same sorts of games can be played with the online Quizlet flashcards. There are several study modes.

and then take the Quick test on organelles, or the self-marking online test.


Activity 3: Drawing the organelles

Play this screen cast and complete the  diagram activity sheet from the Resources above.

Use bold clear lines and always label the structures.


Activity 4 - Test your knowledge

Test your understanding using these IB style questions on eukaryote organelles

Alternatively play this an online Eukaryote organelle shooting game:

Teachers' notes

This page is part of a series of lesson resources for the diagrams of the IB syllabus.
The simple diagram is designed especially as one which is easy for students to replicate under exam conditions. A more detailed diagram link is always given to support understanding and raise awareness of the beauty and complexity of biological systems.

Some students can learn a diagram and it's labels easily, but many students need help to remember the precise shapes and sizes of the parts of each diagrams, and they need practice to get the labels correct and to understand the labels. The resources on this page aim to help teachers support these students.

There are many ways to use this page.

  • Students can work independently or as a group.
  • The resources can be projected in the classroom or studied on a computer.
  • Worksheets allow you to print as much or as little as you wish.
  • Differentiation is possible, as students could follow their own learning pathways to the IB style questions.

Screencast - Ways of using these Flashcards in a lesson (4 mins)

A Suggested Lesson Plan.

Starter: 10 minutes

  • Students complete the Diagram Activity worksheet while watching the Screencast as a whole class.

Main: 40 minutes

  • Students study printed (or online) Flashcards to help memorizing of the labels
  • Students take a Quick test - to see how well they understand the labels
  • Students review the Screencast and attempt the diagram (with labels) from memory.

End: 10 minutes

  • Plenary - students play the arcade game to further consolidate learning
  • Differentiation - students who need additional time for main can continue independently.

Homework

Complete the IB style questions.
