What is nematocyst in biology?

nematocyst, minute, elongated, or spherical capsule produced exclusively by members of the phylum Cnidaria (e.g., jellyfish, corals, sea anemones). ... After eversion, the thread separates from the nematocyst. The threads of some nematocysts ensnare small prey by wrapping about them.

Whats are in nematocyst?

Each cell contains a large capsule organelle called nematocyst. Inside the nematocyst is a thread-like, coiled, hollow tube with toxic barbs. This tube is everted from the capsule to deliver a paralyzing sting to the target prey or enemies.

What are nematocysts and its function?

Nematocysts or cnidocysts represent the common feature of all cnidarians. They are large organelles produced from the Golgi apparatus as a secretory product within a specialized cell, the nematocyte or cnidocyte. Nematocysts are predominantly used for prey capture and defense, but also for locomotion.

What is nematocyst answer in English?

A nematocyst is a stinging cell found on cnidarians such as jellyfish and sea anemones.

What is nematocyst Class 9 answer?

Solution. The stinging cells present at tentacles of aquatic animals like jelly fish, hydra, etc in phylum coelenterata is called nematocyst (cnidoblast)

What is a nematocyst quizlet?

Nematocyst. stinging structure within each cnidocyte of a cnidarian that is used to poison or kill prey.

What is the importance of Nematocyst?

The functions of nematocysts are to attack predators. Nematocysts are small stinging cells that are located on the tentacles of jellyfish.

What is Nematocyst question answer?

What is nematocyst Where do you find this?

Nematocysts are found in the phylum Cnidaria, which includes jellyfishes and sea anemone. Also called cnidocyte or cnidoblast, these are specialized cells found in the tentacles of jellyfish capable of projecting a thread-like structure as a form of self-defence or to capture prey.

Why does a feeding polyp need tentacles?

This colony of polyps will then bud medusae, continuing the life cycle. The medusae feed using tentacles to bring prey to the mouth. The tentacles contain nematocysts, or cells that sting the prey and are also used for protection.

What are nematocysts Class 5?

What are nematocysts Class 5? A capsule within specialized cells in the tentacles of cnidarians, such as jellyfish and corals, containing a barbed, threadlike tube that delivers a toxic sting to predators and prey.

What is polyp and medusa?

There are two basic cnidarian body shapes: a polyp form, which is attached to a surface; and an upside-down free-floating form called a medusa. Some cnidarians change form at different phases of their life cycle, while others remain in one form for their entire life.
