From a photograph and/or slide of cells, make calculations of growth
based on mitotic divisions.
||A team of up to 6 biologists.
||The photograph and slides will be supplied
by the judges. Bring pencils, paper, eraser and calculator.
- make calculations of growth based on mitotic divisions.
i) the identification of mitotic phases.
ii) an estimation of the time required for cell division to take
place based on a given time for one of the phases.
iii) an estimation of growth rate based on calculations in ii)
and calculation of the time required for a specific growth to
SAMPLE PRACTICE QUESTION:
eg. If metaphase takes an average of 25 minutes in an onion
root tip, how long would it take the root to grow 5 mm.
- Students must communicate their calculations in a logical, scientific
format. They will be judged on their process of measurement and
communication as well as their accuracy. All biologist teams will
be given the same micrograph.
