Question: In general, all the natural openings of nematodes are situated on…
Options:
Dorsal side
Ventral side
Lateral side
All of these
✅Explanation:
Nematodes have a distinct body plan with specific regions for different functions. Their natural openings, which include the mouth, vulva (in females), anus, and excretory pore, are all located on the ventral side of their body.
Nematodes have a distinct body plan with specific regions for different functions. Their natural openings, which include the mouth, vulva (in females), anus, and excretory pore, are all located on the ventral side of their body.
🔑Key Points: :
Nematode anatomy is bilaterally symmetrical, with a distinct dorsal and ventral side.
All natural openings are located on the ventral side, a defining characteristic of nematode body organization.
This arrangement is likely related to their movement and feeding habits, allowing them to interact with their environment efficiently.
