Stinging cells will paralyze the prey of the Hydra. This makes it a lot easier for them to capture their food.

What is the origin of the green pigment in hydra organisms?
Hydra's live sybiotically with Chlorella(Green Algae). The Chlorella provides food for the Hydra and is still alive, this explaining the green pigmentation in Certain Hydra's.
Is hydra a autotroph or a heterotroph?
The green hydra (Chlorohydra viridissima) gets its colour from green algae which live inside its tissues in a mutually beneficial relationship. The algae living inside the hydra benefit from having a sheltered safe environment and obtain food by-products from the hydra. The hydra also benefit from algal products. from www.offwell.free-online.co.uk/hydra.htm Hydra eat one celled animals, small crustaceans, worms, insects and other tiny animals. They are also reported to eat small fish fry in the aquarium, where they do occasionally show up. Hydra have a saclike body and a circle of tentacles at around the body opening. This opening is used for both taking in food and eliminating wastes. from http://www.naturalaquariums.com/inverts/hydra.html So this would make them heterotrophs. AliceJM
How does a stem store food?
A stem itself does not store food. The thing that stores food is the vacuole that is found in the cells. These cells make up the stem.
What is the shape of leaf cells that make food?
Palisade cells are the plant cells that make food. They are a vertically elongated shape and absorb a major portion of the light energy used to make food.
How does oxygen and food get to the cells in your body?
Human cells obtain the much-needed food and oxygen via the bloodstream.
What animals catch food and protect themselves with their stinging cells?
Insects.
What do hydra and volvox have in common?
They are both producers of food
How do polyps and Medusa obtain food?
They use stinging cells, the stinging cells use there sharp spines and when the stinging cell touches prey the thread like structure explodes out of the cell and into the prey. Some stinging cells also release venom into the prey. When the prey becomes helpless, the polyp and medusa use there tentacles to pull the prey into there mouth
What are the survival techniques of jellyfish?
Jellyfish use stinging cells to protect themselves & catch food
How do stinging cells help a jellyfish in capturing food?
I would guess they paralyze their prey, and the cells are more effective on smaller prey.
How do cindarians obtain their food?
Cnidarians obtain food by using stinging cells to catch they're food or prey. How: well, When the stinging cell touches the prey, this threadlike structure explodes out of the cell and into the prey. Some stinging cells also release venom into they're prey. When the prey becomes helpless, the cnidarian uses its tentacles to pull the prey into its mouth. From there, the prey passes into a hollow central body cavity, where it is digested. Undigested food is expelled through the mouth.
What cell type in a cnidarian traps food?
In a cnidarians, all cells are in contact with their watery environment in which diffusion occurs through the cell membrane.
How do tentacles help a jellyfish get its food?
Jellyfish tentacles contain stinging cells, which can cause minor irratation or even death to humans or creatures. They than use their tentacles to their food up to their mouths where it is than eaten.
What is a hydra plant?
A hydra is a simple, multi cellular animal. It has a number of tentacles around its mouth, which are used for ingestion of food. The tentacles entangle small aquatic animals and kill them using their stringing cells. They then push them into the mouth. Inside the body cavity the digestive juices secreted by surrounding cells help to digest food. This is then absorbed through cavity walls and assimilated in the cells.
Is the hydra intracellular digestion or extracellular digestion?
hydra is a coelentrate marine organism. it has a unique digestive system which is both extracellular & intracellular. first the ingested food is digested extracellularly & then intracellularly. extracellular digestion takes place in the body cavity of hydra which is called coelentron by the digestive enzymes secreted by gland cells of endodermal layer which is called gastrodermis. then the partially digested food is engulfed by the cells of gastrodermal layer in the form of food vacuoles. further digestion takes place in these food vacuoles.
What does hydra feed on?
Since Hydra is part of the group of cnidarians, it is a bit more complicated than a sponge. The way that hydra digest their food is through extracellular digestion. This means that hydra actually have a special gut cavity that traps and digests food instead of having a bunch of cells do it, like a sponge. This gut cavity only has one opening and during digestion, enzymes from the cell wall are released to aid in breaking down the food. Once digested, the food is engulfed by cells from the wall into tiny particles through a process called Phagocytosis.
How are oxygen and food circulated in hydra?
Diffusion
