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.
Distinguishing Characteristics: The cell nucleus is bound by a double membrane called the nuclear envelope. This membrane separates the contents of the nucleus from the cytoplasm. Like the cell membrane, the nuclear envelope consists of phospholipids that form a lipid bilayer.The envelope helps to maintain the shape of the nucleus and assists in regulating the flow of molecules into and out of the nucleus through nuclear pores. Chromosomes are located within the nucleus.ike the cell membrane, the nuclear envelope consists of phospholipids that form a lipid bilayer.
