There isn't a single, more "scientific" term for "cell" than just "cell" itself. It's a fundamental unit of life, and the term is widely accepted and understood in the scientific community.

However, depending on the context, you might use more specific terms like:

* Prokaryotic cell: This refers to cells without a nucleus or other membrane-bound organelles, like bacteria.

* Eukaryotic cell: This refers to cells with a nucleus and other membrane-bound organelles, like those found in plants, animals, fungi, and protists.

* Somatic cell: This refers to any biological cell forming the body of a multicellular organism other than gametes, germ cells, gametocytes or undifferentiated stem cells.

* Gamete: This refers to a mature haploid male or female germ cell that is able to unite with another of the opposite sex in sexual reproduction to form a zygote.

So, while "cell" is the most common and general term, the specific type of cell you are referring to may determine a more precise term.
