How does a sponge obtain and digest food?
How do sponges obtain and digest food? The sponges draw water carrying food particles into the spongocoel using the beating of flagella in the choanocytes. The food particles are caught by the collar of the choanocyte and brought into the cell by phagocytosis. Digestion of the food particle takes place inside the cell.
Do sponges have an incomplete digestive system?
Sponges lack a dedicated independent digestive system. Instead, the inner walls of sponges are lined with cells known as choanocytes, that have long flagella used to catch and consume bacteria sized particles in the water. Other cells are also responsible for collecting necessary nutrients.
How do sponges actually feed?
Sponges feed by straining food particles from water. As water enters a sponge, Page 2 it carries tiny organisms such as bacteria and protists. Collar cells on the inside of the central cavity trap these food particles and digest them. Sponges are very efficient at removing food particles from water.
Do sponges give off food and oxygen from the water?
The most vital role in the physiology of sponges is played by the water current flowing in and out of their body through the canal system. The complete life of the sponges depends on their canal system. Food and oxygen are brought into the body and excreta and reproductive bodies are carried out through the canal system.
How does a sponge acquire and digest food quizlet?
How do sponges obtain food? They are suspension feeders/filter feeders. They capture food particles suspended in the water that passes through pores in their body. You just studied 22 terms!
How does a sponge obtain nutrients?
Sponges have a unique feeding system among animals. Instead of a mouths they have tiny pores (ostia) in their outer walls through which water is drawn. Cells in the sponge walls filter food from the water as the water is pumped through the body and the osculum ("little mouth").
Do sponges have a digestive system?
Phylum Porifera is a group of simple animals that includes the sponges. Porifera have no internal organs, nervous tissue, circulatory system, or digestive systems, making them the most primitive of the multi-cellular animals.
How do sponge obtain food from water?
The body of sponges contains a hollow cavity, which has pores. From these pores, water enters into the body cavity. Using this water, the sponges capture their food.
Where does digestion take place in sponges?
Food vacuolesSo, the correct answer is 'Food vacuoles'.
How does a sponge obtain food if it Cannot move?
All adult sponges are sessile, meaning they are attached to some surface. Since they cannot move, sponges cannot pursue their food. Instead, they are filter feeders, meaning they obtain their food by straining the water for small bits of food like bacteria, algae, or protozoans.
What type of digestive system do sponges possess?
Lacking a true digestive system, sponges depend on the intracellular digestive processes of their choanocytes for their energy intake. The limit of this type of digestion is that food particles must be smaller than individual cells.
How does a sponge eat without a mouth?
Sponges are filter feeders. They pump water into their body through their pores. The water flows through a large central cavity called the spongocoel (see Figure above). As the water flows by, specialized collar cells (which are also known as choanocytes) filter out food particles such as bacteria.
Which structure of a sponge filters and digests food?
Collar Cell. The collar cells of sponges trap and digest food.
What does a sponge eat?
So how do sponges eat? Sponges are mostly filter feeders and they eat detritus, plankton, viruses and bacteria. They also absorb dissolved nutrients directly from the water through their pinacocyte cells; each cell is responsible for getting their own food!
How does a sponge work?
As water filters through a sponge's porous exterior, the sponge gains some motion, receives food and oxygen, and dispels waste. Inside the sponge, tiny hairlike structures called flagella create currents to filter bacteria out of the sponge's cells and trap food within them.
What does a sponge eat?
So how do sponges eat? Sponges are mostly filter feeders and they eat detritus, plankton, viruses and bacteria. They also absorb dissolved nutrients directly from the water through their pinacocyte cells; each cell is responsible for getting their own food!
How does a sponge get oxygen?
Respiratory organs are lacking in sponges; oxygen is supplied by a direct exchange between the tissues and the surrounding water. Excretion occurs through both the oscula and the surface of the sponge. Special amoebocytes disintegrate in the mesohyl, and their granules are expelled through the canals.
How do sponges get food and digest it?
Sponges are filter-feeders that use a process called osmosis to extract food particles from water.
What digests their food intracellularly?

What do sponges consume and how do they do it?
The majority of sponges consume small organic particles and plankton that they filter from the water that passes through their bodies. Food is gathered by choanocytes, which then transport it to other cells through amoebocytes.
How do sponges get food and digest it?
To acquire food and oxygen, as well as to eliminate wastes, they depend on maintaining a continuous water flow through their bodies. As water is pushed through the body and the osculum, cells in the sponge walls filter food from the water (“little mouth”).
What defenses do sponges have?
What Are Sponges’ Self-Defense Mechanisms? Sponges mainly defend themselves using compounds, which are either poisonous or unpleasant to eat. Sponges, on the other hand, may profit from predation in part because predatory sponge pieces frequently survive and re-establish themselves as independent organisms.
How can an asexual sponge reproduce?
It floats about for a few days before settling down to start growing into an adult sponge. Sponges may also reproduce in an asexual manner via budding.
How do sponges get their oxygen?
Instead, they have pores called ostia that run the length of their bodies. They use them to filter water and other liquids.
What are the three layers that make up a sponge’s body?
Sponges come in three different body types: asconoid, syconoid, and leuconoid. Tubular asconoid sponges have a central shaft called the spongocoel. Water enters the spongocoel via pores in the body wall when choanocyte flagella beat. The spongocoel is lined by choanocytes, which filter nutrients from the water.
Is there a neurological system in sponges?
The only multicellular creatures without a nervous system are sponges. They are devoid of nerve and sensory cells. Touch or pressure to the exterior of a sponge, on the other hand, causes a local contraction of the sponge’s body.
