What makes a tunicate more complicated than a sea sponge?
Umnica [9.8K]

Given what we know, we can confirm that in summary, what makes a tunicate more complicated than a sea sponge is cellular differentiation.

<h3>What is cellular differentiation?</h3>

This is what we call the cells ability to specialize itself into a specific cell type. Some examples of this in humans include:

  • Heart cells
  • Digestive cells
  • Reproductive cells
  • etc.

Due to this, tunicates have evolved different tissues, organs, and complete cell types, making them much more complicated organisms than sea sponges.

Therefore, we can confirm that due to the multiple tissues, organs, and systems developed through cellular differentiation, tunicates have become more complicated than sea sponges.
