Ergosterols
In fungal cell walls, which polysaccharide other than chitin is mentioned in the text?
Mannan
What role do ergosterols play in the structure of fungal cells according to the text?
Membrane support and permeability
Which of the following structures is NOT mentioned in the context of fungal cell walls?
Glucagon
Which organisms have no cell walls?
Animals
What is the major cell wall component in plants?
Cellulose
Which organisms share a commonality with plants in terms of cell wall composition?
Fungi
What distinguishes animals from plants and fungi in terms of cell structure?
Absence of cell walls
Which group of organisms exhibit cellulose as the major component of their cell walls?
Plants and some protists
What is a key feature that distinguishes fungi from animals?
Presence of chitin in the cell wall
Which component is responsible for giving fungi a rigid structure?
Chitin in the cell wall
What is the main function of the chitin in the fungal cell wall?
Providing structural support
Which type of fungi possesses a cell wall made of chitin?
All fungi
How does the non-motility of fungi relate to their cell wall composition?
Fungi have chitin in their cell walls, making them non-motile.
Study Notes
Fungal Characteristics
- Fungi have a rigid cell wall, which makes them non-motile.
- Cell walls of fungi are composed of chitin, providing rigidity and support.
- Fungal cell walls also contain mannan and other polysaccharides.
- The cytoplasmic membrane of fungi contains ergosterols.
- Fungi differ from animals in having a cell wall, whereas animals lack a cell wall.
- Fungi also differ from plants, which have cellulose as their main cell wall component.
Test your knowledge on the structure of fungal cells, including characteristics like chitin in cell walls and ergosterols in the cytoplasmic membrane.
