Which of the following kingdoms lacks the presence of a nucleus and cellular division by mitosis?

Ectoderm
Microtubules
Monera
Zygote

The correct answer is: Monera

Monera, or the kingdom Monera, is a prokaryotic kingdom and is the only one to lack a nucleus. Ectoderm and zygote are not kingdoms, but rather types of cells or developmental stages. Microtubules are a component of cells and are not a kingdom.
