Question

immature cells that have the potential to develop into many, but not all, classes of mature cells (e.g., blood, skin, hair, neurons) are called: ependymal pluripotent multipolar ventricular totipotent

Explanation:

• Ependymal cells are a type of glial cell that line the ventricles of the brain and the central canal of the spinal cord. They are not stem cells.
• Pluripotent stem cells have the ability to differentiate into many different cell types (but not all). For example, embryonic stem cells are pluripotent.
• Multipolar neurons are a type of neuron with multiple dendrites and one axon. They are not stem cells.
• Ventricular refers to something related to a ventricle (e.g., in the heart or brain). It is not a type of stem cell.
• Totipotent stem cells can develop into any type of cell in the body, including extra - embryonic cells. The question specifies "not all" classes of mature cells, so totipotent is incorrect.

Answer:

pluripotent
