Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
An Amoeba in a drop of pond water divides by binary fission every minutes, and every daughter cell does the same. Starting from one cell, how many divisions take place in hours, and how many cells are there then?
Need a reminder? The key ideaShow
In asexual reproduction one parent makes new individuals without gametes: fission (binary in Amoeba and Leishmania, multiple in Plasmodium), fragmentation (Spirogyra), regeneration (Planaria), budding (Hydra), spores (Rhizopus) and vegetative propagation in plants. In binary fission each round doubles the number of cells.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Divisions. minutes, and divisions.
Step 2. Cells. cells.
Answer: divisions and cells.
