Which of the following model organisms would be the best choice if you wanted to to and in vivo study of early animal cellular division?

Xenopus  

Mouse

E. coli

Arabidopsis

Drosophila

Solution

Model organism is an organism selected for intensive scientific study based on features that make it easy to work with in the hope that findings will apply to other species .

The correct answer is Arabidopsis. The aerial parts of the plants are generated by group of dividing cells called shoot apical meristem. To analyse, cell behaviour in these structures, we developed a technique to visualise living shoot apical meristems using confocal microscope. This method combined with fluorescent marker lines and vital stains, allows us to follow dynamics of cell proliferation and division.
