HORTICULTURE

Detailed explanation-1: -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-2: -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).

Detailed explanation-3: -Plant and animal cells have nuclei, making them eukaryotic. Eukaryotes are creatures with a nucleus encased inside a nuclear envelope in their cells. Therefore, among the characteristics that are not found in plants is (C) Prokaryotic cells.

Detailed explanation-4: -Chloroplasts are types of plastids that possess green pigment. They play a critical function in the plant cells as they are the site of photosynthesis in the plant cells. Animal cells do not synthesize food, and thus, they do not need to capture the sunlight, and therefore, they lack plastids (pigmented organelles).

Detailed explanation-5: -Chitin, a polymer of N-acetyl-D-glucosamine, is a component of the fungal cell wall and is not found in plants.
