Nuclear+Membrane

=The Nuclear Membrane! =

= The Nuclear Membrane is the lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. It was discovered by Scottish botanist Robert Brown in 1833 with a light microscope that allowed for a close examination of cellular structure. =

= Functions of the Nuclear Membrane: **The Nuclear Membrane has small holes in it known as Nuclear Pores which allow material to pass in and out of the nucleus. Anything that needs to pass between the nucleoplasm and cytoplasm can only do so through these pores. They only allow small molecules, ions, and proteins to freely move into or out of the nucleus.**=

==**The type of cells that contain a nuclear membrane are all eukaryotic cells. Why? Because all eukaryotic cells have a nucleus, and for the nucleus to not have random molecules passing in and out of it uncontrollably, it needs to have a nuclear membrane. The type of cell that does not have a nuclear membrane (yes there are some) are prokaryotic cells. Why? As you should know already, prokaryotic cells have no nucleus, such as some bacteria. If prokaryotic cells do not have a nucleus, then there is no way that it can have a nuclear membrane. The nuclear membrane needs the nucleus to protect.**==



= Does the nuclear membrane work with other organelles? =

Answer: Yes
=== The nuclear membrane works mostly with two main organelles of a cell, the endoplasmic reticulum, and the nucleus. The nuclear membrane shares a common border with the ER and some materials actually come from it. The nuclear membranes' primary job is to surround and control what passes in or out of the nucleus, similar to the cell membrane. ===
