What helps circulate water through the sponge?
Water circulation through a sponge is primarily facilitated by the movement of specialized cells called choanocytes, which have flagella that create a water current. This current draws water into the sponge through tiny pores called ostia, allowing for the intake of nutrients and oxygen while expelling waste through larger openings called oscula. The porous structure of the sponge, along with its unique cellular arrangement, aids in maximizing water flow throughout its body.
What is the function of flagellum in sponges?
In sponges, flagella are primarily found on specialized cells called choanocytes. The beating of these flagella creates a water current that facilitates the flow of water through the sponge's body, allowing for the filtration of food particles, bacteria, and oxygen. This water movement is essential for the sponge's feeding, respiration, and waste removal processes. Additionally, it helps maintain the sponge's internal structure by providing a continuous flow of nutrients and gases.
How does the orange puffball sponge eat?
The surface of the orange puffball sponge is covered with small pores that filter small particles of food from the water that passes through them. Each sponge has flagella that help move the water through the sponge.
What cell type in sponges is responsible for producing the water current through the sponge?
Collar cells, also known as choanocytes, are responsible for producing the water current through sponges. These specialized cells have flagella that generate the current, bringing in food and oxygen while expelling waste.
The collar cells draw water through the sponge's many pores and into the internal cavity of the sponge by beating their?
flagella
Which structure would create currents when the sponge is feeding?
The structure that creates currents in a sponge during feeding is the choanocytes, or collar cells. These specialized cells have flagella that beat to generate water flow through the sponge's body, drawing in water laden with food particles. The collar of microvilli around the flagella helps trap and filter these particles, allowing the sponge to feed efficiently. This flow of water is essential for both feeding and respiration in sponges.
How do pores help a sponge feed?
Pores in a sponge allow water to flow through its body, facilitating the process of feeding. As water enters through the pores, it carries tiny food particles and microorganisms, which are filtered out by specialized cells called choanocytes. These cells use their flagella to create a water current and trap food particles, allowing the sponge to absorb nutrients while expelling waste through larger openings. This filtration system enables sponges to efficiently feed and thrive in their aquatic environments.
What are little whips that move through the sponge?
Little whips are flagella that help pump water through the pores for food.
Tell how a sponge accomplishes each of the nine life processes?
A sponge eats and breathes by filtering water through its body. Different cells perform these life processes. Water flows through numerous pores in the sponge's skin. These pores lead into a central cavity, the spongocoel, which is lined with choanocytes, or collar cells. Each collar cell has a flagella, a tiny whiplike structure that creates a current to help draw
How is water moved through a sponges central cavity?
Water is moved through a sponge's central cavity, known as the spongocoel, by the action of specialized cells called choanocytes. These cells have flagella that beat rhythmically, creating a flow of water into the sponge through small openings called ostia. As water flows through the spongocoel, it is filtered for nutrients and oxygen, which are absorbed by the sponge's cells. The filtered water then exits through a larger opening called the osculum.
What does a sponge use to capture food?
A sponge captures food using specialized cells called choanocytes, or collar cells. These cells have flagella that create a water current, drawing in water and small food particles such as bacteria and plankton. The collar of microvilli around the flagellum traps these food particles, which are then engulfed by the choanocytes through phagocytosis. This process allows sponges to efficiently filter-feed from their surrounding environment.
Why is it necessary that flagella inside a sponge keep water from moving through its body?
So that they can take their food from the water.
