Answer:

The nematocyst is absent in hydra. Option c is the correct answer.

Explanation:

• The layer of cells that line the gastrointestinal tract of hydra is known as gastric skin.
• Nutritional muscle cells, glandular cells, nerve cells, sensory cells, and stromal cells are located in the lining of the gastric skin of hydra.
• There are no cnidarian cells or nematode cysts. Hydra is a lonely polyp found in freshwater.
• Known as one of the smallest polyps found in the marine environment, the hydra is carnivorous in the diet.
• Hydra is ectoderm and has a degree of tissue division of labour. Hydra has a cylindrical body with 6 to 10 tentacles.
• These are hollow tentacles that aid in movement and feeding.

Hence, nematocyst is absent in hydra.
