Final answer:
The Golgi apparatus in plant cells synthesizes complex carbohydrates including starch and cellulose, of which the latter serves as dietary fiber in the human diet as it cannot be digested by humans.
Step-by-step explanation:
Yes, the Golgi apparatus, or Golgi bodies, in plant cells are responsible for synthesizing polysaccharides such as starch and cellulose, which includes dietary fiber. In plants, these complex carbohydrates play critical roles, including energy storage and structural support for the cell walls. However, while animals like humans can break down starch into glucose, they cannot digest cellulose due to the lack of the enzyme cellulase. Instead, cellulose acts as dietary fiber, promoting a healthy digestive tract and reducing the risk of various diseases.
Golgi bodies are not the only structures involved in the handling of carbohydrates. Excess sugars in plants and animals can be converted into storage forms such as glycogen, which in animals is stored in the liver and muscles to be used during periods of energy demand, like long-distance running.
