VCE Biology – Unit 1
Cell size, structure and function
•
•
•
cells as the basic structural feature of life on Earth, including the distinction between prokaryotic and
eukaryotic cells
surface area to volume ratio as an important factor in explaining the limitations of cell size and the need for
internal compartments (organelles) with specific cellular functions
the ultrastructure of plant and animal cells in terms of their organelles and identification of these organelles
using the light microscope and electron micrographs

Task 3
The diagram below is an Escherichia coli cell, a typical bacterial cell. Label the structures seen in this cell.
Task 4
Label the organelles shown in the diagrams of the plant and animal cell below (after you decide which one is which).
Task 5
The following cells are either plant or animal cells. Determine the cell type, justify your choice and label organelles.
