Learning Goals

Name five specialised cells and their jobs in an organism.
Identify at least one structural feature that makes each cell good at its job.
Explain how a cell's shape suits its function.

Warm Up

Label the diagram

The five specialised cells below are labelled A–E. Use your lesson notes to write the name of each cell and one specialised feature it has.

A = Red blood cell · B = Neuron · C = Sperm cell · D = Palisade mesophyll cell · E = Root hair cell

Your Turn

Sort it!

Write each feature from the pool into the correct category box below. Some features may apply to more than one cell — write them in all boxes that apply.
