Why are the walls of the windpipe made of stiff material?
The walls of the windpipe (trachea) are made of cartilage rings to prevent collapse and maintain an open passageway for air to flow in and out of the lungs. The stiff material provides support and protection to keep the trachea open during breathing and prevent blockages.
What a stiff layer of nonliving material that surrounds a plant cell?
Cell Wall
A stiff layer of nonmoving material that surrounds a plant cell?
The cell wall which is composed of cellulose
In the wall of tube A there are 'rings' of a stiff material called cartilage.Suggest one function of the 'rings' of cartilage?
The rings of cartilage in the wall of tube A, which is likely a reference to the trachea, serve to provide structural support and maintain the shape of the airway. They prevent the tube from collapsing during inhalation and exhalation, ensuring that air can flow freely to and from the lungs. Additionally, the rigidity of the cartilage helps protect the airway from external pressure.
What makes a cell stiff?
The cell wall
The C-shaped rings that provide support for the wall of the trachea are made out of?
The C-shaped rings that support the wall of the trachea are made out of hyaline cartilage. These rings help maintain the structure and prevent collapse of the trachea during breathing.
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 are the stiff surfaces that support a cell called?
Cell wall
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.
How do you remove moss from cement wall?
Wash, using a stiff brush.
What is a stiff layer of nonliving materials that surrounds a plant cell?
This layer is called a cell wall,
Why don't animals cells need a cell wall?
The cell wall is an extra layer of protection for plant cells. The cell wall is stiff so as to keep the shape of the cell. Since plants must be stiff or else they will droop, having stiff cells makes that happen. Animal cells don't need to worry about having stiff cells because animal cells just float around throughout the organism...plant cells must be stiff and aligned next to each other.
