How flatworms get energy?
Different types of flatworms eat different types of food such as bacteria or protozoans. They send digestive juices out of the opening in their digestive tract to partially digest the food, then they suck all of this up back into their gastrovascular cavity where it is fully digested and provides energy to the flatworm.
Where do cnidarians digest their food?
Hmmm, Mrs Perry's class I see. It occurs in the gastrovascular cavity.
What do flatworms have that sponges and cnidarians dont?
Flatowrms have muscle cells, they are a triploblastic phylum. They have endo, meso and ectoderm layersSponges are Parazoa and lack any true tissue at allCnidaria are diploblastic, having only endoderm and ectoderm
How jellyfish eats?
They digest food using the gastrodermal lining (a sort of acidic membrane) of the gastrovascular cavity (a hole on its underside), where nutrients are absorbed.
Do flatworms digest food?
Yes they do digest food.
What is the hydra digestive system like?
Cnidarians and flatworms have a gastrovascular cavity. Cnidarians, such as the hydra, use their tentacles to move food through their mouth into their gastrovascular cavity. Then the cells lining this cavity excrete digestive enzymes that will start extracellular digestion and break the prey into smaller pieces. Any undigested remnants of the prey are expelled through the mouth opening. Like cnidarians, flatworms have a gastrovascular cavity with a single opening, but the cavity itself is highly folded. These folds greatly increase the surface area and extend throughout the body, bringing nutrients within the reach of all cells.The gastrovascular cavity of cnidarians and flatworms allows them to digest larger prey than they could with intracellular digestion. However, the effectiveness of a gastrovascular cavity in supplying the animal with nutrients is limited. Because there is only one opening to the external environment through which prey is taken in and remnants are expelled, the animals have to complete digestion of the first prey and expel its remnants before taking in another prey. With the evolution of a second opening in the digestive system, the digestive system became a digestive tract, or alimentary canal, making it a one-way system between mouth and anus. Food could now be taken in and processed continuously, providing the animal with more nutrients. Most animals-including vertebrates, arthropods, mollusks, round worms and earthworms-have this form of digestive tract.A one-way digestive tract is efficient because it allows the food to pass through a series of specialized regions. Such regions may be specialized for protein, fat, or carbohydrate digestion, making each step more efficient. Other regions may be used for food storage or for preparing the food for chemical digestion by physically grinding it into smaller pieces, which exposes more surface area to the action of digestive enzymes. These specialized regions eventually evolved into organs as parts of a complex digestive organ system. However, because nutrient dispersal, by the digestive system itself to all cells of the body, was no longer feasible with such a specialized digestive system (and animals became larger and bulkier) a separate cardiovascular system evolved to serve that function.
How do jellyfish obtain the water it needs?
Since a Jelly fish does not a a specialized digestive, osmoregulatiry, central nervous, circulatory, and respiratory systems. They will digest using the gasrtrodermal lining of there gastrovascular cavity were most of there nutrients are absorbed. So I'm guessing that is were they get most of there water too.
How is digestion in fungi different from digestion in human beings?
Most fungi digest their food by extracellular digestion, or at least some hydrolysis occur beforehand. Meaning the food is broken down in compartments that are continuous with the outside of the fungi's body. Example of such an compartment: Gastrovascular cavity.
What is the job of the oral cavity?
to digest
Is extracellular digestion the same as saprophytic digestion?
As far as I know there is no such thing as saprophytic digestion, however a saprophyte is any organism that live on dead matter. I know however that saprophytic fungi digest their food extracellularly, meaning the food is broken down in compartments that are continuous with the outside of the specie's body (i.e Gastrovascular cavity found in many animals with relatively simple body plans.)
How do cnidarians digest their food?
Extracellularly in a digestive cavity.
How do annelids get their energy?
they get by eating
