Question

name the cell which don't have a well being defined a nuclear membrane​

Answer 1

Answer:

The nuclear envelope consists of two lipid bilayer membranes, an inner nuclear membrane, and an outer nuclear membrane.[4] The space between the membranes is called the perinuclear space. It is usually about 20–40 nm wide.[5][6] The outer nuclear membrane is continuous with the endoplasmic reticulum membrane.[4] The nuclear envelope has many nuclear pores that allow materials to move between the cytosol and the nucleus.[4] Intermediate filament proteins called lamins form a structure called the nuclear lamina on the inner aspect of the inner nuclear membrane and gives structural support to the nucleus.[4]

A prokaryotic cell

Explanation:

A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle.
