Myles Quinn · Answer 1

The correct answer is option D. Fungal cell walls contain chitin rather than cellulose.

Explanation:

Plants and the fungi are thought to be different forms of the plant because they share many similar characters such as both have cell wall and many more.

But plants and fungi also different in many characters such as fungi cell wall made up of chitin while plants have cellulose in their cell wall which is shown main component of the insect and arthropods.

thus, the correct answer is option D. Fungal cell walls contain chitin rather than cellulose.
