Nearly all corals and some other cnidarians are attached and are called sessile .
Free floating DNA is typically found in prokaryotic cells, such as bacteria, where it can exist as plasmids or extrachromosomal DNA. Eukaryotic cells, like those in plants and animals, generally do not have free floating DNA outside of the nucleus.
Free floating nucleotides are individual units of nucleic acids, such as DNA or RNA, that are not part of a larger nucleic acid chain. These nucleotides can serve as building blocks for synthesizing new DNA or RNA strands. They are also important for various cellular processes, such as protein synthesis and energy storage.
Proteins made on free-floating ribosomes are generally used within the cytoplasm of the cell, where they can participate in various cellular processes. These proteins may also be targeted to specific organelles within the cell or secreted outside of the cell to perform their functions.
They are the ribosomes. They synthesize proteins in cell
The digestive tract and reproductive organs of an Ascaris are free floating within the body and do not attach to the body wall. Ascaris do not have any other internal organs other than the gut and internal reproductive organs, as breathing and waste excretion are handled externally within the body wall.

Cnidarians are segmented into two main classes: Anthozoa (sea anemones and corals) and Medusozoa (jellyfish and hydrozoans), based on their body forms. Anthozoa are generally sedentary, with a polyp body form, while Medusozoa are typically free-swimming with a medusa body form.

Cnidarians, which include jellyfish, corals, and sea anemones, exhibit two primary body forms: the polyp and the medusa. The polyp is a sessile, cylindrical form that attaches to a substrate, while the medusa is a free-swimming, bell-shaped form. Both forms have a gastrovascular cavity for digestion and specialized cells called cnidocytes that contain stinging structures. The life cycle of many cnidarians involves a transition between these two forms.
A Cnidarian is a stinging animal such as a jellyfish or a sea anenome. They have stinging cells that they use predatorially for food. There are two body scructures for cnidarians--polyps and medusas. A polyp is attached to something and does not move, and its mouth is at the top. A medusa is free-swimming, and its mouth is on the bottom.
The polyp body form is a cylindrical, sessile stage found in certain cnidarians, such as hydras and sea anemones. It typically has a mouth at the top surrounded by tentacles, which are used for feeding and defense. Polyps are usually anchored to a substrate and can reproduce asexually, often by budding. This form contrasts with the medusa stage, which is free-swimming and often bell-shaped.
Free Floating was created in 2006.
Hydra - the polyp, anchored with a stalk, tentacles up; and medusa, the jellyfish, swimming free, tentacles down. All cnidarians have both stages, like larva and adult, but they spend more time in one of them and are known as that stage, for example anemones and jellyfish. Anemones have a tiny jellyfish dispersal stage, and jellyfish have a tiny polyp reproduction stage.
The two body forms of cnidarians are the polyp and the medusa. Polyps are typically sessile, tube-shaped organisms attached to a substrate, while medusae are free-swimming, umbrella-shaped organisms.
Cnidarians in their medusa form typically exhibit a bell-shaped, free-swimming body structure. They have a gelatinous umbrella-like body called the bell, which is equipped with tentacles hanging downwards, containing specialized cells called cnidocytes for capturing prey. The body is radially symmetrical, with a central mouth opening surrounded by the tentacles, and they possess a simple nerve net for coordinating movement. This structure allows them to effectively navigate and capture food in their aquatic environments.
