A. Requires flowers (vegetative id related to flowers.)
The correct answer is: Differentiate
Every cell in a multicellular organism has an identical genome, and yet, there are various cell types. These varieties are the result of highly controlled modifications in gene expression (different sets of genes must be turned on and off).
Cellular differentiation almost never involves a change in the DNA sequence itself. Therefore, different cells can have very different physical characteristics regardless of having the same genome.
The most observable difference is the way in which cytokinesis occurs. In plants a new cell wall is fashioned between the new daughter cells, while in animal cells the cell membrane constricts to pinch the parent cell into daughter cells.
I would think of a unicellular organism or a plant, but I'm not too sure on this one, Just trying to help :)
