What is the origin of the green pigment in hydra organisms?
The green pigment in hydra organisms, called "hydra-chlorophyll," is not produced by the hydra itself but is obtained from the algae that live symbiotically within its cells. This pigment allows for photosynthesis to occur within the hydra and provides energy for the organism.
The single opening of hydra and the pseudopod of the amoeba are both involved in the process of?
Both the single opening of a hydra and the pseudopod of an amoeba are involved in the process of feeding. The hydra uses its single opening to capture and ingest prey, while the amoeba extends its pseudopod to engulf food particles through phagocytosis.
What is stinging cells cniderians locomotion?
Cnidarians, such as jellyfish, use stinging cells called nematocysts for defense and capturing prey. Their locomotion is typically achieved through pulsating movements of their bell or umbrella-shaped body, allowing them to move through the water. Additionally, some cnidarians like corals may remain stationary and rely on water currents to bring food and oxygen to them.
How do gonozoids obtain their food in this colonial organism?
Gonozoids in colonial organisms, such as a siphonophore, obtain food by catching prey using their tentacles equipped with stinging cells called nematocysts. Once the prey is captured, the gonozoids use their digestive system to break down the food and absorb nutrients for energy.
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
What are some special traits of stinging cells?
Stinging cells contain a specialized organelle called a cnidocyte that releases toxins when triggered. These toxins can immobilize or kill prey, and in some cases, deter predators. The cells are found in organisms like jellyfish and hydra, and are important for defense and capturing food.
Do sponges have stinging cells?
No, sponges do not have stinging cells like those found in cnidarians (e.g., jellyfish and sea anemones). Sponges are filter feeders that rely on water flow to capture food particles, rather than using stinging cells for prey capture.
What animals catch food and protect themselves with their stinging cells?
Insects.
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.
What do hydra and volvox have in common?
They are both producers of food
What cell type in a cnidarian traps food?
Specialized stinging cells called cnidocytes in cnidarians like jellyfish, sea anemones, and corals are responsible for capturing food. These cells contain nematocysts, which are used to inject toxins into prey and defend against predators.
What is the origin of the green pigment in hydra organisms?
The green pigment in hydra organisms, called "hydra-chlorophyll," is not produced by the hydra itself but is obtained from the algae that live symbiotically within its cells. This pigment allows for photosynthesis to occur within the hydra and provides energy for the organism.
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.
Where are the digestive enzymes of Hydra produced?
The digestive enzymes in Hydra are produced in their cells, specifically in the gastrodermis, which lines the inner cavity of the body column. These enzymes help break down food particles that are ingested by Hydra for absorption and nutrient acquisition.
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.
