Final answer:
C. elegans (Caenorhabditis elegans) is the model organism with over 1500 genes coding for transcription factors, making it an important organism to study in cell development.The correct option is C. Caenorhabditis elegans (worm)
Step-by-step explanation:
The organism that has over 1500 genes coding for transcription factors and is important to study in cell development is C. elegans (Caenorhabditis elegans).
C. elegans is a free-living nematode that is less than a millimeter long. It has a simple structure with about 1000 cells and a genome of only 20,000 genes. Its transparency allows researchers to easily observe and monitor changes in the organism.
Additionally, every cell can be visualized and identified, making it a useful organism for studying cellular phenomena like cell-to-cell interactions, cell fate determinations, cell division, apoptosis, and intracellular transport. The correct option is C. Caenorhabditis elegans (worm)
