Biology Revision Questions

This is a list of short questions which may be useful for revising Biology as it covers a wide variety of topics. I will post the answers to the questions separately in the next post.

I did not write these questions or design the layout so I cannot take credit for it but I have it so thought it would be useful for others too!



_________________________________________________________________________________

The following questions are taken from past Leaving Certificate Examination Papers (2004 - 2011).  Questions on the same topic have been separated to provide random revision. If questions are repeated it only highlights their greater significance or importance as they have been asked more often over the years.

N.B. These questions do not cover the entire syllabus. Knowing the answers to these questions only is not a guarantee of an excellent result.
