cell walls with chitin

Detailed explanation-1: -The answer is (c) Cell walls of chitin. (c) Cell walls of chitin. The existence of a cell wall characterizes plant cells. The cell wall is made of cellulose and not chitin.
Detailed explanation-2: -Centrosomes are present in animal cells and absent in plant cells. Hence the absence of the centrosome is the only characteristic of the plant cell.
Detailed explanation-3: -Kingdom fungi include multicellular, heterotrophic eukaryotes with the chitinous cell wall.
Detailed explanation-4: -Chitin, a polymer of N-acetyl-D-glucosamine, is a component of the fungal cell wall and is not found in plants.
Detailed explanation-5: -The most characteristic component found in all plant cell walls is cellulose. It consists of a collection of -1, 4-linked glucan chains that interact with each other via hydrogen bonds to form a crystalline microfibril (Somerville, 2006).
