Cell Wall Flashcards
What is the structure of the cell wall in plants?
It is a rigid outer layer made of cellulose with multiple layers.
What is the composition of the cell wall in fungi?
It is made of chitin.
What is the nature of the cell wall?
It is tough somewhat flexible and made of multiple layers.
What is the primary cell wall?
It is the thin flexible outer layer that provides structural support and allows for growth during cell expansion
What is the secondary cell wall?
It is a thicker more rigid layer inside the primary cell wall of mature plant cells. It often contains lignin and other substance that enhance durability
Where is the cell wall located?
Just outside the cell membrane. Only found in plant cells.
Do animal cells have cell walls?
No, they only have a cell membrane.
What is one primary function of the cell wall?
It provides structural strength helping maintain the cell’s shape and preventing collapse.
Does the cell wall act as a protective barrier?
Yes, it shields the cell from damage and harmful external factors.
How does the cell wall regulate growth in plant cells?
It regulates the direction of growth by controlling cell expansion.
What role does the cell wall play in preventing cell bursting?
It prevents cell bursting when water enters through osmosis.
