6. Animal Cell Slide Place a drop of methylene blue on your slide
Rub the inside of your cheek with a cotton swab then rub it on your slide
Place your swab in disinfectant DO NOT put in on the table
Carefully lower a cover slip over the sample, use a pencil to help you
Make sure you have no air bubbles

7. Scientific Drawing Make a scientific drawing of an animal cell.
Rules of scientific drawings:
Use only straight lines
Do not colour or shade in
Label each part with a straight line. No arrow head

8. Animal Cell Write the title Animal Cell in your jotter
Copy the animal cell diagram below
Cell Membrane
Nucleus
Cytoplasm

11. Plant Cell Slide
Peal off a thin layer of onion tissue and place on a slide
Carefully spread the piece of tissue out so that there are no folds
Place a couple of drops of iodine on the onion tissue
Carefully lower a cover slip over the sample, use a pencil to help you
Make sure you have no air bubbles

12. Scientific Drawing Make a scientific drawing of a plant cell.
Rules of scientific drawings:
Use only straight lines
Do not colour or shade in
Label each part with a straight line. No arrow head

14. Cell structure and function
Each part of a cell has its on role to play in the working of it. Using the cards match each cell structure to its function. (you have 2 minutes)

The control centre of a cell.
This controls what substances can enter and leave the cell.  
The jelly like filling of a cell. This is where chemical reactions take place in a cell.   
The rigid firm coating found around a plant cell. It helps to keep the cell shape.  
Contain a green chemical called chlorophyll which absorbs sunlight. Allow plants to make their own food. 
Can store sugar and water. Helps to control the water content of plant cells  

Animal Cell Plant Cell Microbial Cells
Similarities and Differences?

20. In your jotter… Microbial Cells Microbial cells do not have a nucleus.
Examples of microbes
Bacteria: Lactobacillus, E. coli

21. Some cells are specialised for a particular job
Some cells are specialised for a particular job. Below are pictures of plant, animal and bacterial cells. They all look different because they have different jobs to do.

22. Can you think of reasons why they look this way?
Bacterial cell
Root cell
Sperm cell
Windpipe cell
Leaf cell
Blood cell
Pollen cell
Nerve cell

23. How big are cells?
Arrange the pictures in order from biggest to smallest…

3D Model

43. Challenge
Your challenge is, in pairs, to create a 3D model of a cell using the materials provided. Paper Glue Plastic tubs Pens Balloons Card (different colours) Jelly Sandwich bags (medium/small) Peas Foam Paper plates (big/small) Sponges Marbles Bubble wrap Lollypop sticks
Once all models are complete you will each take turns going round looking at each others and giving feedback.

44. Some ideas

45. First, plan your 3D cell model
First, plan your 3D cell model. You may look at the materials available, but ask first if you want out your seat. Paper Glue Plastic tubs Pens Balloons Card (different colours) Jelly Sandwich bags (medium/small) Peas Foam Paper plates (big/small) Sponges Marbles Bubble wrap Lollypop sticks You may not start building your model until I have seen your plan.
