Science March Holiday Project

***Remember to choose only Plant Cell OR Animal Cell to make your model.

1) Criteria for Model of Cell:
-2D model
-Not bigger than A4 size
-You may use cardboard or plastic container as the base for the model.
-Use recycled materials that can be found at home to make the model. You do not need to buy materials.

Note: Do not use coloured candies or food as they will attract ants.

2) Labelling
You are only required to label and create these parts:
Animal cell:
Nucleus
Cell Membrane
Cytoplasm
Plant cell:
Nucleus
Cell Membrane
Cytoplasm
Chloroplasts
Cell Wall

3) Research on the different parts of the 2 types of cells (Plant OR Animal) and their functions. 
You are required to make and label ONLY the required parts.
Note: You may wish to include other parts that you are not required to make but it is optional.  

Think of suitable materials that can best represent the different parts of the cell that have their own specific characteristics and functions.

A gallery walk will be conducted in class on 25/3(Wed) after your March holidays. You have to explain the reason for your choices to your peers.

Note: I would advise you to spend 30mins to do research and 30 mins to make your model.


Happy holidays 5B! I hope you will enjoy the process of learning and discovering more about the topic while making your cell model.

  1. Can we not make the model? I do not have any plasticine and I will be very busy as I would have my CCA camp from Monday to Wednesday and the rest of the week would be spent rushing to and fro from the tuition centre for make up.

    1. Hi Rui Wen,

      You may design & draw the model, labelling the type of recycled materials used for various parts of the cell. In this way, you can still share your idea during the gallery walk on why you choose to use the various recycled materials.

    1. You should only take 30min to make the model. Hence, i'd suggest not to do a 3D model as it would require a longer time spent to complete it.

    2. Mrs tan but how is it supposed to be 2D?Do you mean draw and cut?
      So making a 3D is optional but you do not suggest it?

    3. I think ill make the 3D one

    4. Me too. I don't know how to do it in 2D.

  3. Hi Shyan and Sebastian, a 2D model is one that displays a flat representation of 2 dimensions(length and breadth) whereas a 3D model displays the 3 different dimensions(width, depth and height). As such, a 3D model would be more time-consuming to make. An example of a 2D model can be made using paper cut-outs, by putting layers over layers of papers. For instance, a large rounded paper cut-out that is used to represent the nucleus can be placed over the base paper that is used to represent the cytoplasm.
    You may wish to create a 3D one if it is easier for you, but it is optional. You can just use suitable 3D objects and arrange them in the structure of a plant cell or animal cell.

    Examples of 2D Cell:

    As you can see, the depth and the height of the parts of the cell are not visible here. This is a 2D representation.

  5. Can I stick my model on an A4 size paper?

  9. So we can stick papers on top of each other?

    1. Yes, so long as they are arranged in the structure of a plant or animal cell. -Ms Pan

  10. But a root cell plant does not have a chloroplast.

    1. Hi Cheryl, yes, you are right. A root cell does not have chloroplasts but it is a plant cell as it is taken from a part of the plant. If you are doing a plant cell based on a root hair cell, then your cell model will not have chloroplasts. We will explore more about the parts of root hair cells and the reasons for the absence of chloroplasts for root hair cell during our Lab session.
