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.
A double-layered membrane, the nuclear envelope, separates contents of the nucleus from the cellular cytoplasm. The envelope is riddled with holes called nuclear pores that allow specific types and sizes of molecules to pass back and forth between the nucleus and the cytoplasm. double-layered membrane, the nuclear envelope, separates contents of the nucleus from the cellular cytoplasm.
