Question

ctenophores capture food: a. with filter feeders. b. using adhesive glue cells that trap prey. c. with stinging hair cells that immobilize small invertebrates. d. with poison in their tentacles that capture small invertebrates. e. by digging through the bottom mud for small invertebrates.

Answer 1

The correct answer is option C: "Ctenophores capture food with stinging hair cells that immobilize small invertebrates."

Ctenophores, also known as comb jellies, are marine organisms that capture their food by using specialized structures called colloblasts. These colloblasts contain stinging cells, similar to the ones found in jellyfish. When a ctenophore comes into contact with a small invertebrate, the stinging hair cells discharge a sticky substance that immobilizes the prey. This allows the ctenophore to capture and consume its food.



To summarize, ctenophores capture their food by immobilizing small invertebrates using stinging hair cells.
