The walls of the trachea are made rigid by the presence of rings of cartilage. These rings extend from the larynx to the bronchial tubes.

Each plant cell has a rigid outer layer called a cell wall. Animal cells do not have this structure.
The thick outer layer of a plant cell is called the cell wall... 8) A.I
None. Plant cells are rigid due to the cellulose based cell wall they make just outside the cell membrane.
yes, the chest wall becomes more rigid and the lungs themselves stiffen
No, Plants and bacteria have rigid cell walls. we humans have a membrane
The cell wall makes plant cells rigid.

cell wall
The cell wall keeps the structure contained and rigid, and the chloroplast makes chlorophyll for photosynthesis.
Cellulouse makes the cell wall more rigid and hard to defend the cell.
The thick outer layer of a plant cell is called the cell wall... 8) A.I
A cell wall makes a cell more rigid and makes it less permeable which is beneficial as it can prevent stuff from easily flowing in or escaping.
plant cell walls are made of cellulose, which makes them rigid
None. Plant cells are rigid due to the cellulose based cell wall they make just outside the cell membrane.
A plant cell is like a brick in that its shape is rigid. A plant cell has a cell membrane like an animal cell, but it also has a cell wall, which an animal cell does not. The cell wall is made of a tough, rigid substance - chitin. The rigid and durable properties of chitin are what makes grass stick up and spring back up after you've stepped on it.
