Does bacteria have a cell wall a nucleus or one celled?
Bacteria are nearly always single-celled organisms, and are also considered prokaryotes. Prokaryotic cells do not have an enclosed nucleus, rather genetic material "floats" around inside the cytoplasm. They do have a cell membrane enclosing them, but its not as stiff as the cell "wall" of a plant. Plants are unique in their stiff cell wall structure; most cells are simply enclosed by a flexible membrane.
Opening into the trachea is called?
The inside of the trachea is called the tracheal wall, the rings tracheal rings. The inside of the trachea is called the tracheal wall, the rings tracheal rings. The inside of the trachea is called the tracheal wall, the rings tracheal rings.

What part in a plant cell is strong and stiff?
The still part of a plant cell is called Cell Wall. This is the rigid outermost layer of a plant cell. It makes the cell stiff -providing the cell with mechanical support - and giving it protection. It is found just inside the cell wall and is made up of complex lipids (fats) and proteins.
What is the stiff outside of the membrane called?
Membranes do not have a stiff outside. I suspect the answer you are looking for is the cell wall, which is a stiff structure found outside the cell membrane of a plant cell, but separate from it.

Cartilage is necessary in the wall of the trachea because it supports the trachea and keeps it open at all times. New born babies do not have these rings of cartilage around their trachea, which is why their heads need to always be supported carefully.

cartilage
