Functions of Spikes in a Sponge

Oct 13, 2025 by miodeya.com 69 views

Sponges are simple multicellular organisms that belong to the phylum Porifera. They are found in aquatic environments and play a crucial role in the marine ecosystem. One of the distinctive features of sponges is the presence of spikes or spicules, which are made of silica or calcium carbonate. These spikes serve various functions, and in this article, we will explore which of the given options is an example of a function of spikes in a sponge.

What are Spikes in a Sponge?

Spikes in a sponge refer to the sharp, pointed structures that are embedded in the sponge's body. These spikes are made of silica or calcium carbonate and are responsible for providing support and structure to the sponge. They are also involved in the defense mechanism of the sponge, helping to protect it from predators and other external threats.

Functions of Spikes in a Sponge

The spikes in a sponge serve several functions, including:

Providing structure: The spikes in a sponge provide support and structure to the sponge's body. They help to maintain the sponge's shape and prevent it from collapsing.
Helping the sponge breathe: The spikes in a sponge also play a role in the sponge's respiratory system. They help to increase the surface area of the sponge, allowing it to exchange gases more efficiently.
Defending the sponge: The spikes in a sponge help to defend the sponge from predators and other external threats. They can cause injury to predators and deter them from attacking the sponge.
Providing attachment: The spikes in a sponge can also help to attach the sponge to a substrate, such as a rock or a coral reef.

Which of the Given Options is an Example of a Function of Spikes in a Sponge?

Based on the functions of spikes in a sponge, we can conclude that the correct answer is:

B. Helps the sponge breathe

The spikes in a sponge help to increase the surface area of the sponge, allowing it to exchange gases more efficiently. This is an example of a function of spikes in a sponge.

Conclusion

In conclusion, the spikes in a sponge serve several functions, including providing structure, helping the sponge breathe, defending the sponge, and providing attachment. The correct answer is B. Helps the sponge breathe, as this is an example of a function of spikes in a sponge.

Q: Why are spikes in a sponge important?

A: Spikes in a sponge are important because they play a crucial role in the sponge's survival and success. They provide support and structure to the sponge, help it to breathe, defend it from predators, and attach it to a substrate.

Q: Can spikes in a sponge be harmful to humans?

A: No, spikes in a sponge are not typically harmful to humans. However, it is possible to get injured by a sponge spike if you touch it or try to remove it from the sponge.

Q: How do sponges produce spikes?

A: Sponges produce spikes through a process called biomineralization. This process involves the use of specialized cells called sclerocytes, which produce the silica or calcium carbonate that makes up the spikes.

Q: Can sponges regrow their spikes?

A: Yes, sponges can regrow their spikes if they are damaged or removed. This is because sponges have the ability to regenerate their tissues, including their spikes.

Q: Are all sponges the same when it comes to spikes?

A: No, not all sponges are the same when it comes to spikes. Different species of sponges have different types of spikes, and some may have more or fewer spikes than others.

Q: Can spikes in a sponge be used for anything else?

A: Yes, spikes in a sponge can be used for other purposes, such as:

Filtering water: Spikes in a sponge can help to filter water by trapping small particles and debris.
Supporting other organisms: Spikes in a sponge can provide support for other organisms, such as algae or small animals.
Providing habitat: Spikes in a sponge can provide habitat for other organisms, such as fish or invertebrates.

Conclusion

In conclusion, spikes in a sponge are fascinating structures that play a crucial role in the sponge's survival and success. They provide support and structure to the sponge, help it to breathe, defend it from predators, and attach it to a substrate. By understanding the functions and importance of spikes in sponges, we can gain a deeper appreciation for these incredible organisms and the important role they play in our ecosystem.
