A+ students - trichocysts
when Paramecium is attacked, the compact crystalline structure shoots out of the cell and is propelled by its own decondensation. One shot takes less then a millisecond! It then adopts a second more relaxed and irreversible crystalline conformation, which has lengthened by a factor of 8 (25-35m) and is stable.

Very small bottle shaped structure on a paramecium used for defense?
Trichocyst is a very small bottle-shaped structure found in paramecia that is used for defense. When a paramecium senses a threat, it discharges the trichocysts to release long, sharp structures that can deter predators or capture prey.
What is paramecium-?
Paramecia are single cell organisms usually less than one hundredth inch long. They are a genus of protozoa of the phylum Ciliophora. They feed mostly on bacteria.Paramecium is a member of a group of unicellular slipper shaped ciliate protozoa called Paramecia.
Is a paramecia unicellular?
Yes, a paramecium is a unicellular organism. It belongs to the group of protists and is characterized by its complex structure, including cilia for movement and feeding. Paramecia are commonly found in freshwater environments and play a role in the ecosystem by feeding on bacteria and other microorganisms.
What are eukaryotes that aren't plans fungi or animals called?
Eukaryotes that are not plants, fungi, or animals are called protists. This diverse group includes organisms such as algae, amoebas, and paramecia. Protists can be both unicellular and multicellular and are found in various environments, including freshwater, marine, and soil habitats.
What is a animal-like protist?
Animal-like protists are called protozoa. Protozoaare single-celled eukaryotes that share some traits with animals. Like animals, they can move, and they are heterotrophs.
What is a type reproduction found in paramecia?

What are some true things about paramecia?
Paramecia are single-celled organisms found in freshwater environments. They move using cilia and feed on bacteria and algae. They reproduce asexually through binary fission.
Paramecia are often found in ponds and streams?

What organelle is found in paramecia cells but not plant cells?
Contractile vacuole is found in paramecia cells but not plant cells. It helps in expelling excess water from the cell to maintain osmotic balance.

What process of digestion do paramecia use?
Paramecium uses the processes of endocytosis and exocytosis. Paramecia are single-celled organisms that can be found in freshwater, brackish and marine environments. They grow in big numbers in stagnant basins and ponds.

Is hydrochloric acid found in nature?
Hydrochloric acid is not typically found in nature in its pure form. However, it is naturally produced in the human body to aid in digestion as gastric acid in the stomach. It can also be found in volcanic emissions and some plants produce it for defense mechanisms.
What is true of paramecia?
The Paramecium is a group of unicellular ciliate protozoa, formerly known as slipper animalcules from their slipper shape. They are commonly studied as a representative of the ciliate group. Paramecia range from about 50 to 350 μm in length, depending on species. Simple cilia cover the body which allow the cell to move with a synchronous motion. There is also a deep oral groove containing inconspicuous compound oral cilia (as found in other peniculids) that is used to draw food inside. They generally feed upon bacteria and other small cells. Osmoregulation is carried out by a pair of contractile vacuoles, which actively expel water absorbed by osmosis from their surroundings. Paramecia are widespread in freshwater environments, and are especially common in scums. Paramecia are attracted by acidic conditions. Certain single-celled eukaryotes, such as Paramecium, are examples for exceptions to the universality of the genetic code (translation systems where a few codons differ from the standard ones).
