Biology 2.8 Describe cell structure and function

Sites for revision

Cells alive!
This website includes interactive activities and supporting information on topics about biological cells, including plant and animal cells, mitosis, and DNA. Suitable for NCEA levels 1 and 2.
http://www.cellsalive.com

Online Biology Book
This website provides information, for students, on biology and chemistry for the biologists. Topics relevant to this standard include cells and cell processes, such as cell division and cellular transport, reactions and enzymes, ATP and biological energy, cellular metabolism and fermentation, photosynthesis, genetics, and protein synthesis. Suitable for NCEA level 2 but be aware that some material is beyond what is required at level 2.
