Pores
ostium ostia
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.
Sponges have pores and are filter feeders
Small pores of sponges are called ostia through which water enters while a large pore through which water exits is called osculum .
a sea sponge uses energy when mating and filtering food :)
A human made sponge is called a sponge because humans used to use sea sponges.
osculum and ostia are the holes in the sponge that can be used as mouths
A sea sponge absorbs water through numerous minute, dermal pores on its body surface known as ostia.
No, it has pores which allow the sponge to filter feed.
The phylum Porifera, commonly known as sponges, has pores in their bodies called ostia. These pores allow water to flow through the sponge, helping with filter feeding and gas exchange.
Loofah?
Sea sponges maintain homeostasis through a combination of simple diffusion and specialized cells called archaeocytes. These cells regulate the flow of water through the sponge's pores, allowing for the exchange of gases, nutrients, and waste products. Additionally, sea sponges can adjust their water flow rate and filter feeding activity to maintain internal stability in response to changing environmental conditions.
