How do cells of the goblet sponge get essential nutrients and gases?
Cells of the goblet sponge obtain essential nutrients and gases through a process called diffusion. This means that they absorb these substances directly from the surrounding water through their cell membranes. This allows the cells to take in the resources they need for metabolism and growth.
Are choanocytes significant to a fundamental process for sponges?
Yes, choanocytes are significant in sponges for feeding and the ingestion of food particles. They create water currents that bring in nutrients which are then captured by their collar cells for consumption. Choanocytes also play a role in reproduction by generating sperm cells.
What is a flagellated cell that sweeps water through a sponge's body?
A flagellated cell that sweeps water through a sponge's body is called a choanocyte. Choanocytes have a flagellum that creates a current to bring water through the sponge's pores, allowing for filter feeding and gas exchange to occur within the sponge's body.
What happens to a sponge when pressed through a coarse cloth bag and extrude the whole cells through the holes?
When a sponge is pressed through a coarse cloth bag, the cells of the sponge are extruded through the holes in the cloth. This process physically breaks down the sponge's structure, separating the cells and disrupting its overall integrity. The final product would resemble a more fibrous material with a different texture compared to the original sponge.
Why are spicules used as a primary characteristic in taxonomy of sponges?
Spicules are microscopic structures that are unique to each sponge species, making them a valuable taxonomic characteristic for identifying and classifying sponges. They can vary in shape, size, and composition, providing detailed information about the sponge's classification and evolutionary history. This makes spicules a key feature for distinguishing between different sponge species.
An amoebalike cell in a sponge that moves through the body cells supplying nutrients and removing wastes?
an "amoebocyte" Spicules are the inorganic, needle-like, calcium carbonate or silicate structures that give a sponge its shape and rigidity.
How does a sponge-like fungus absorb nutrients from its environment?
A sponge-like fungus absorbs nutrients from its environment through its porous structure, which allows it to take in water and dissolved nutrients. These nutrients are then absorbed by the fungus through its cell walls and used for growth and reproduction.
How are nutrients dispersed to all of the cells of a sponge?
In sponges, water containing nutrients flows through numerous channels in their body. Specialized cells called choanocytes capture nutrients from the water and pass them onto other cells in the sponge's body for distribution. This allows for the efficient dispersal of nutrients to all cells in the sponge.
Why is water movement through sponge body important for feeding?
Sponges are animals and are heterotrophs- they need to take in nutrients and food for energy. The nutrients are carried by the water into the sponge.
What is a collar cell's function in a sponge?
They improve both respiratory and digestive functions for the sponge, pulling in oxygen and nutrients and allowing a rapid expulsion of carbon dioxide and other waste products.
Does a sponge have the structures to obtain resources?
Yes it does. All a sponge is, is a dead sea creature.
What structures provide support to the sponge?
What supports a sponge it its agility to love god with all its tentacles, rays, and hole on the bottom of itself.
What does a sponge have instead of a mouth?
osculum and ostia are the holes in the sponge that can be used as mouths
What are the glass like structures on the sponge?
Glass, surprise.
How does a sponge take in nutrients?
By sucking in their food or eating it
Does a sea sponge have a oneway or a twoway digestive system?
Neither. A sea sponge uses diffusion for getting its nutrients.
Is sponge an autotroph?
No. Despite its looks, sponge is an animal which filter feeds, which makes it a heterotroph.In early stages of its life, it is actually motile and moves around until it finds a suitable space to grow and become a sponge. Once it grows, it can bring in water and get the nutrients present in the water through diffusion.
