Sponges eliminate carbon dioxide and cellular wastes by?
allowing them to diffuse into the water that passes through sponge
Are choanocytes significant to a fundamental process for sponges?
The choanocytes move water through the sponge, similar to a digestive tract in higher order mammals. The choanocytes are the primary system for allowing nutrients to be absorbed by the sponge.
The energy producing parts of animal cells are the?
What part of the animal cell is responsible for energy production?
Which process is responsible for the distribution of pheromones through the air?
Diffusion or osmosis.
The egg is propelled down the oviduct by?
Cilia lining moves the human egg through the oviduct. They beat in such a manner that it drives the egg toward the uterus.
What adaptations does a sponge have for obtaining food?
Sponges are filter feeders and use choanocytes to create a current for food particles to pass through its body.
Are sponges motile?
An adult sponge is anchored to the sea floor and doesn't move around but it does have cillia that cause water current to flow through the body of the sponge. Larval sponges will swim using their cillia.
Is it true that young sponges move through the water but adult sponges don't?
yes, it is
What is the function of choanocytes in reproduction of sponges?
Those cells include a single flagellum that surrounded by a contractile collar of microvilli. The choanocytes are responsible for moving water through the sponge and for obtaining food.
How do sponges ingest food?
sponges feed through their pores or holes, their pores create a current pulling food into the central cavity of the sponge. the food sticks to the collar cells that lines the central cavity, there the amoebocytes pick up the food and digest it, carrying the nutrients to the other cells.summary:porescollar cellsamoebocytesother cells.
What is a sponges breathing method?
Diffusion through skin.
How does canal system of sponges do their function?
sponges let the water enter through the canal and circulates all over the body.
What cell type is sponges is responsible for producting the water current through the sponge?
Sponges play an important roll in aquatic ecosystems, acting to filter particles out of the water (especially bacteria), and forming a fairly substantial portion of the coral reef biomass. Sponges are clearly the simplest of the conspicuous animal phyla, and thus are important subjects for considering the evolution of the animals. Recent studies using the tools of molecular genetics indicate that the animal kingdom evolved only once, and that the Phylum Porifera is at the base of the animal tree of life. In this sense, sponges represent a key group for understanding relationships among the other animal phyla.
What group of animals does not go through the gastrula stage?
It's commonly believed that sponges are a group of animals that don't go through the gastrula stage. However, some scientists disagree and believe that sponges do go through gastrulation.
Where are sperm and eggs released in sponges?
In water through canal system .
How many osculum is in sponges?
osculum - a large opening in a sponge through which water flows out of the sponge. Sponges may have more than one oscula.
3 How do sponges reproduce?
Sponges do not give birth. The only animals who give birth to live young are mammals. Sponges reproduce by releasing sperm or eggs into the sea. The sperm and eggs just mix up in the water and form tiny sponges. The "babies" float around until they land, where they grow into new sponges. Some sponges can also form a "bud" that grows into a new sponge without any sex involved.
