Question

cellulose, bacteria having peptidoglycan, and fungi possessing chitin in their cell walls.

plant cell wall structure image with labels: pectin, cross - linking glycan, cellulose microfibrils, middle lamella, primary cell wall, plasma membrane

what is the main material that fungal cell walls are made from?

• amylose
• actin
• chitin

Explanation:

The question is about the main material of fungal cell walls. From the provided text (above the image), it's stated that fungi possess chitin in their cell walls. Amylose is a starch component, and actin is a protein involved in cell structure/movement, not fungal cell wall material. So the correct option is chitin.

Answer:

chitin (the option with "chitin" text)
