A
plants
B
animals
C
llamas
D
bacteria
Explanation: 

Detailed explanation-1: -Starch is the main storage polysaccharide of plants. It is the most important dietary source for human beings. The high content of starch is found in cereals. Cellulose occurs exclusively in plants and it is the most abundant organic substance in the plant kingdom.

Detailed explanation-2: -Starch and cellulose are two types of polysaccharides that are found in plants. However, they have different structures and functions. Starch is primarily used for energy storage, whereas cellulose is used for structure and support.

Detailed explanation-3: -Cellulose is a carbohydrate found in the cell wall of plants. The carbohydrate is a polysaccharide structure. Polysaccharide is made up of a long chain of several sugar units bonded together by chemical linkage. Polysaccharides examples are chitin, glycogen, cellulose, and starch.

Detailed explanation-4: -Cellulose is the most abundant carbohydrate in the plant kingdom, forming the fundamental structure of plant cell walls, where cellulose is closely associated with other components such as hemicelluloses and lignin. Cellulose is distinguished from the starches by their 1 → 4 bonds.

Detailed explanation-5: -Is cellulose the same as carbohydrate? Cellulose is a carbohydrate, as is starch. It is a type of structural polysaccharide, whereas starch is a type of storage polysaccharide.
