Verified step by step guidance

Step 1: Begin by understanding the definition of carbohydrates. Carbohydrates are organic molecules composed of carbon (C), hydrogen (H), and oxygen (O) atoms, typically in the ratio of 1:2:1. They serve as a primary energy source and structural components in living organisms.

Step 2: Analyze the first statement: 'Monosaccharides are the simplest form of carbohydrates.' Monosaccharides, such as glucose and fructose, are single sugar molecules and are indeed the simplest form of carbohydrates. This statement is true.

Step 3: Evaluate the second statement: 'Cellulose is a disaccharide found in animal tissues.' Cellulose is not a disaccharide; it is a polysaccharide composed of glucose units. Additionally, cellulose is found in plant cell walls, not animal tissues. This statement is false.

Step 4: Assess the third statement: 'Carbohydrates do not contain any oxygen atoms.' This is incorrect because carbohydrates always contain oxygen atoms as part of their molecular structure (e.g., glucose: C₆H₁₂O₆).

Step 5: Examine the fourth statement: 'Glycogen is the primary storage carbohydrate in plants.' Glycogen is the storage carbohydrate in animals, while starch is the primary storage carbohydrate in plants. This statement is false.
