You may have seen leeks at the grocery store and wondered what sort of vegetable they were. Well, leeks are part of the onion family and, in fact, look like a giant version of green onions. However, the little green onion has a much stronger onion flavor then the leek. Another difference is that you need to cook leeks before eating them. Unlike an onion, you would not add an uncooked leek to a salad!
Nuclear Pore. Quick look:A nuclear pore is a minute opening or passage way through the nuclear envelope. It connects the nucleoplasm (nucleus) with the cytoplasm. The opening is âpluggedâ with an amazing biological valve that only permits selected chemicals to move into and out of the nucleus.
The nuclear membrane, sometimes referred to as the nuclear envelope, is the membrane that encloses the nucleus. This bilayer membrane is made of lipids, and encases the genetic material in eukaryotic cells. The nuclear membrane is made up of a double lipid bilayer. There are two parts to these two layers: the inner and the outer nuclear membrane. There is a space between the membranes, which is called the perinuclear space.
