Structure and Description Matching
Septal nephridia and pharyngeal nephridia- Both are exonephric
Typhlosole- Helps in grinding the soil particles and decaying leaves
Hepatic caeca- Blind tubules present at the junction of foregut and mid-gut in the alimentary canal of the cockroach
Gizzard- Internal median fold present in the dorsal wall of the intestine of earthworm
Correct Answer: Hepatic caeca- Blind tubules present at the junction of foregut and mid-gut in the alimentary canal of the cockroach
Explanation:
- Septal nephridia and pharyngeal nephridia- Both are exonephric: This description is incorrect because septal nephridia are internal organs present in each segment of the earthworm, which help in excretion while pharyngeal nephridia are external organs present in the head region of earthworms, which help in osmoregulation.
- Typhlosole- Helps in grinding the soil particles and decaying leaves: This description is incorrect because typhlosole is a longitudinal fold present in the intestine of earthworm which increases the surface area for absorption of nutrients.
- Hepatic caeca- Blind tubules present at the junction of foregut and mid-gut in the alimentary canal of the cockroach: This description is correct as hepatic caeca are blind tubules present at the junction of foregut and mid-gut in the alimentary canal of the cockroach. They are responsible for the secretion of digestive enzymes and absorption of nutrients.
- Gizzard- Internal median fold present in the dorsal wall of the intestine of earthworm: This description is incorrect because gizzard is a muscular organ present in the digestive system of birds and some invertebrates which helps in the mechanical breakdown of food. It is not a fold present in the intestine of earthworms.
Therefore, the correct matching of structure and description is Hepatic caeca- Blind tubules present at the junction of foregut and mid-gut in the alimentary canal of the cockroach.
