Stinging cells
What structures help protect sponges from predators?
Spicules
What are the structures for defense for golden retrievers?
the structures of defense can be their claws and sharp teeth
What are thin spiny structures that form the skeleton of many sponges?
The spike forms a rigid frame that helps support and protect the sponges body.
Why are sponges classified as animals than plants?
due to their internal and external structures
What do jellyfish and sponges have that specialized venomous cells used for defense and to help capture prey?
nematocyts :)
What material is found in the skeleton of all sponges?
All sponges have a skeleton made of a protein called spongin or mineralized structures composed of calcium carbonate or silica.
Do cnidarians have spicules?
No, cnidarians do not have spicules. Spicules are small, needle-like structures made of calcium carbonate or silica that are found in some sponges and echinoderms for support and defense. Cnidarians, such as jellyfish and corals, have a different type of support structure called a mesoglea.

How do sponges and cnidarians defend themselves against predators What is different about the methods used by each?
Sponges defend themselves primarily through chemical means, releasing toxic compounds or deterrent substances to repel predators. They also have a simple structural defense, utilizing their porous bodies to make it difficult for larger predators to consume them. In contrast, cnidarians, such as jellyfish and sea anemones, use specialized cells called cnidocytes that contain stinging structures called nematocysts, allowing them to deliver venom to deter or incapacitate predators. This reliance on stinging cells represents a more active and immediate form of defense compared to the passive chemical defenses of sponges.
Infer how spongin and spicules discourage predators from eating sponges?
Spongin is a tough, fibrous protein that provides structural support to sponges, making them difficult to consume. Spicules are tiny, needle-like structures made of calcium carbonate or silica that can be sharp and harmful if ingested by predators. Together, these structures make sponges unpalatable and unattractive to most predators.
