                                                     TASK DESCRIPTION

Create representations of plant or animal cells. This will include:
1. A representation and analysis of the structure of two specialised plant or two specialised animal cells that
   is related to their function
2. How understanding plant or animal cell function contributes to developments in health treatments.

E     Describes a cell
Note:
The plant and animal cells may be represented in any way you choose which might include a
model, detailed diagram or a computer generated image. However, this must be able to be
completed in the time allotted to the assessment task.

The representation should include responses to the following two sections:

1. Specialised plant or animal cells

     •       Select two specialised plant or animal cells with different functions (e.g. plant — root and
             leaf; animal — muscle and neuron).
     •       Create a representation of the specialised cells.
     •       Describe the structure and function of the specialised cells.
     •       Research the distribution of specific organelles in each specialised cell.
     •       Relate the function of the specific organelles to the overall function of the specialised cell.
     •       Compare the differences in distribution of specific organelles in terms of the two specialised
             cells function in the organism.

2. Understanding plant or animal cells for better health

         •    Select one specialised plant cell (e.g. root, leaf, petal) or one specialised animal cell (e.g.
              liver, muscle, neuron, kidney) to research.
         •    Research and explain the cell’s function in the organism.
         •    Identify potential problems that can affect the function of a specialised cell and
              consequences for the organism (e.g. Understanding that human pancreatic cells may be
              damaged affecting insulin production which results in type 1 diabetes. A fungal infection in
              leaf cells called ‘leaf spot’ destroys chloroplasts preventing photosynthesis.)
         •    Outline how the application of scientific understanding leads to treatments being used to
              address these problems (e.g. To treat type 1 diabetes insulin injections are required. To
              treat leaf spot spray the plant with a fungicide to kill the fungus.)
