A trichocyst can be found in tetrahymena and along cila pathways of several metabolic systems.
It is also a structure in the cortex of certain ciliate and flagellate protozoans consisting of a cavity and long, thin threads that can be ejected in response to certain stimuli. Trichocysts may be widely distributed over an organism or restricted to certain areas (e.g., tentacles, papillae, around the mouth). There are several types. Mucoid trichocysts are elongated inclusions that may be ejected as visible bodies after artificial stimulation. Filamentous trichocysts in Paramecium and other ciliates are discharged as filaments composed of a cross-striated shaft and a tip. Toxicysts (in Dileptus and certain other carnivorous protozoans) tend to be localized around the mouth. When discharged, a toxicyst expels a long, nonstriated filament with a rodlike tip, which paralyzes or kills other microorganisms; this filament is used to capture food and, presumably, in defense.The functional significance of other trichocysts is uncertain, although those of Paramecium apparently can be extruded for anchorage during feeding.

Which of the following act for protection of body (defensive) in some ...
Trichocysts are the structures that act for protection of the body (defensive) in some protozoa.
Trichocysts are specialized organelles found in certain groups of protozoa, such as ciliates and dinoflagellates. These organelles are essentially microscopic harpoon-like structures that can be discharged rapidly in response to a threat or disturbance. Trichocysts are localized within the cytoplasm and are composed of a long, coiled thread-like filament.
When a protozoan encounters a potential threat or disturbance, the trichocysts are discharged. This process involves the rapid extension of the filament, which is propelled out of the cell membrane. The discharged filament can entangle or immobilize the predator or threat, providing a defensive mechanism for the protozoan.
Trichocysts are primarily used for defense, but they can also be used for capturing prey or for attachment to surfaces. They provide a physical barrier against predators or other threats, allowing the protozoan to protect its body and ensure its survival.
In summary, trichocysts are specialized organelles found in certain protozoa that act as a defensive mechanism. They are rapidly discharged in response to a threat or disturbance, providing a physical barrier against predators and protecting the body of the protozoan.
