Which structure would create currents when the sponge is feeding?
The structure that creates currents in a sponge during feeding is the choanocytes, or collar cells. These specialized cells have flagella that beat to generate water flow through the sponge's body, drawing in water laden with food particles. The collar of microvilli around the flagella helps trap and filter these particles, allowing the sponge to feed efficiently. This flow of water is essential for both feeding and respiration in sponges.
What are the flagellated cells in the interior of a sponge called?
The flagellated cells in the interior of a sponge are called choanocytes. These specialized cells have a collar of microvilli surrounding a central flagellum, which they use to create water currents and filter food particles from the water. Choanocytes play a crucial role in the sponge's feeding and digestion processes.
Food adaptations for the moon jellyfish?
The moon jellyfish has a feeding tentacle that hangs at each corner of its mouth. The tentacle has stinging cells that are used to capture small prey and drag it to its mouth.
What type of animal has a collar cells an osculum and spicules?
An animal with collar cells, an osculum, and spicules is likely a sponge. Sponges are simple aquatic animals that filter feed using collar cells and have a central opening called an osculum through which water exits their bodies. Spicules are tiny, hard structures that provide support and structure to the sponge's body.
What is another name for collar cells?
labarrion rusell labarrion rusell labarrion rusell labarrion rusell
How many chromosomes are in a jellyfish's cells?
Jellyfish typically have 36 chromosomes in their cells.
What cells are in jellyfish?
water cells
How do epithelial like cells control filter feeding in sponges?
Epithelial-like cells in sponges help control filter feeding by lining the channels and chambers where water is drawn in and filtered. These cells have specialized structures like microvilli and cilia that aid in capturing food particles as water flows through. By regulating the flow of water through these channels, the epithelial-like cells play a crucial role in efficient filter feeding in sponges.
How does a jellyfish's stinging cells work?
A jellyfish's stinging cells, called nematocysts, contain a coiled thread that can rapidly eject when triggered. When a potential threat or prey comes into contact with the jellyfish's tentacles, the nematocyst fires, injecting venom through a tiny harpoon-like structure. This venom can paralyze or harm prey, allowing the jellyfish to capture it for feeding. The rapid discharge of the nematocyst is a specialized adaptation for both defense and predation.
What are pore cells and collar cells?
collar cell- choancyte that is most likely in sponges
Where is collar cell found?
Choanocytes (also known as "collar cells"). Choanocytes are found dotting the surface of the spongocoel in asconoid sponges and the radial canals in syconoid sponges, but they comprise entirely the chambers in leuconoid sponges.
How do jellyfish contain cells?
Jellyfish are composed of cells just like any other organism is.
