Question

Sting cells are present in 
a) amoeba
b) hydra
c) spider
d) butterfly​

Answer 1

Answer:

Explanation:

Cnidarians contain specialized cells known as cnidocytes (“stinging cells”) containing organelles called nematocysts (stingers). These cells are present around the mouth and tentacles, and serve to immobilize prey with toxins contained within the cells.

The hydra's stinging cells are more properly known as cnidocytes, which cover the outside of their tentacles. The hydra uses these barbed, poisonous cells to catch and stun prey such as water fleas and plankton.
