FAQs on Cockroach: Digestive System Video Lecture - Biology Class 11 - NEET
| 1. What is the role of the digestive system in cockroaches? |  |
Ans. The digestive system in cockroaches is responsible for the breakdown and absorption of nutrients from their food. It consists of various organs such as the mouth, esophagus, crop, gizzard, stomach, and intestine, which work together to facilitate digestion and absorption.
| 2. How does the cockroach's digestive system differ from that of humans? | |
Ans. The cockroach's digestive system differs from that of humans in several ways. Cockroaches have a simpler digestive system with fewer specialized organs compared to humans. They lack a true stomach and do not have a separate gallbladder or pancreas. Additionally, cockroaches can digest cellulose, which is a complex carbohydrate found in plant material, whereas humans cannot.
| 3. What happens to food in the cockroach's crop? | |
Ans. The cockroach's crop acts as a temporary storage organ for food. When the cockroach ingests food, it passes through the esophagus and enters the crop. In the crop, the food is stored and moistened, allowing the cockroach to consume larger quantities of food in a short period. From the crop, the food then moves to the gizzard for further processing.
| 4. How does the cockroach's digestive system adapt to its omnivorous diet? | |
Ans. The cockroach's digestive system is well-suited for its omnivorous diet, which includes both plant and animal matter. Cockroaches have a specialized structure called the gizzard, which is responsible for grinding and breaking down tough food particles. This adaptation allows them to efficiently digest a wide range of food sources and extract nutrients from them.
| 5. Can cockroaches survive without a functional digestive system? | |
Ans. No, cockroaches cannot survive without a functional digestive system. The digestive system is essential for their survival as it enables them to obtain nutrients from their food. Without a properly functioning digestive system, cockroaches would be unable to break down and extract nutrients from their food, leading to malnutrition and eventual death.
