Specialized collar cells lining the pores of a sponge called choanocytes are responsible for capturing tiny food particles. These cells have flagella that create water currents, bringing in food particles and directing them towards the collar where they are trapped and ingested by the cell.
What else can I help you with?
Explain why filtering can trap undissolved particles?
Filtering can trap undissolved particles because the filter has tiny pores that are smaller than the particles being filtered. As the liquid passes through the filter, the particles get stuck in these pores, preventing them from passing through with the liquid. This allows the filtered liquid to flow through while trapping the particles.
When a material takes in or soaks up a liquid?
This process is called absorption. The material absorbs the liquid by taking it into its structure or pores. The absorbed liquid can change the properties of the material, such as its volume or texture.
Why do colloids cannot pass through membranes but do with filter paper?
Colloids cannot pass through membranes because their particles are too large to fit through the membrane pores. However, they can pass through filter paper because filter paper has larger pores that allow colloidal particles to pass through while trapping larger particles.
Why does the the water passes through the filter paper but not the cornstarch?
The water actually passes through the filter paper and the cornstarch. However, the cornstarch does not pass through the filter because the molecules are to large.
When you squeeze a sponge under waterwhat are the bubble that escape?
When you squeeze a sponge underwater, the bubbles that escape are composed of air that was trapped inside the sponge's pores. As you apply pressure, the air is forced out from the sponge in the form of bubbles that rise to the water's surface.
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 is the body of a sponge covered in with many small?
The body of a sponge is covered in tiny openings called pores. These pores allow water to flow in and out of the sponge, which helps the sponge filter out food particles and oxygen from the surrounding water.
Regulate both the flow of water and the flow of materials that pass through the pores of a sponge?
The body of a sponge helps regulate the flow of water by efficiently channeling it through its pores, allowing for filtration and nutrient intake. At the same time, the sponge controls which materials pass through its pores by utilizing specialized cells to selectively take in beneficial substances while filtering out unwanted particles.
How does a sponge feed?
through its pores and holes
How does a sponge absorb water?
A sea sponge absorbs water through numerous minute, dermal pores on its body surface known as ostia.
The way a sponge obtains food is similar to which of the following?
They are filter feeders. They filter water through they're pores and extract the particles from the water.
Does a sponge contain air?
Yes, a sponge can contain air within its pores when it is soaked with water. As the sponge absorbs water, air is displaced and trapped within its structure.
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.
Does sponges a sponge get oxegyn from water?
Water is brought through cilia-lined pores into the hollow cavity of the sponge. As water passes through the pores, the cilia trap oxygen to breathe
What are pores and where are pores on a sponges body?
Allow materials to enter and leave the sponge
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 is the name of the tiny pores in a sponge through which water is absorbed?
ostium
