Most of the nucleated cells in a multicellular organism contain all of the genetic
information for the organism. Which of the following cells does not fall into this category?
Nerve Cell
Sperm Cell
Epithelial Cell
Parenchymal Cell

Sperm cells are unique in that they carry only half the genetic information of a multicellular organism. While all other nucleated cells, like nerve, epithelial, and parenchymal cells, contain the full set of chromosomes, sperm cells are haploid, meaning they contribute just one set of genes to an embryo during fertilization.

This reduction in genetic material is crucial for sexual reproduction, allowing for genetic diversity when combined with an egg cell, which is also haploid. Each new organism then inherits a complete set of genes from its parents, creating unique combinations that fuel evolution and adaptation!
