no it eats cake
Sponge are not segmented.
Sponges do not have specialized respiratory organs or systems, so they rely on simple diffusion to obtain oxygen from their surroundings and release carbon dioxide. The process of cellular respiration does occur in sponge cells to generate energy, but it does not involve complex respiratory structures like in other animals.
No.
Sponges respire through simple diffusion of gases across their body surface. They do not have specialized respiratory organs like lungs or gills. Oxygen from the water is absorbed directly into their cells, while carbon dioxide produced by cellular metabolism is released back into the surrounding water.
In sponges, gases such as oxygen and carbon dioxide are exchanged primarily through the process of diffusion. Water flows through the sponge's porous body, allowing oxygen to diffuse from the water into the sponge's cells while carbon dioxide produced by cellular respiration diffuses out into the surrounding water. This simple gas exchange is facilitated by the sponge's unique body structure, which maximizes surface area for efficient nutrient and gas transfer.
A dry sponge is hard because the water has evaporated, leaving the sponge's cellular structure collapsed and less flexible. When water is added, the cells absorb water and expand, allowing the sponge to become soft and flexible.
no it is not a type of plant only coral and things like seaweed and kelp
A sponge domain is a type of protein domain characterized by its ability to bind and regulate various biomolecules, often involved in cellular signaling or structural functions. These domains are typically rich in proline, glycine, and other flexible residues, giving them a "sponge-like" quality that allows them to accommodate different partners. Sponge domains play a crucial role in cellular processes by modulating interactions with other proteins, RNAs, or lipids, thereby influencing various biological pathways.
The movement of water provides a simple mechanism for feeding respiration circulation and excretion.
The spicules of some sponges focus and direct sunlight to cells lying below the surface of the sponge, where symbiotic organisms carry out photosynthesis.
Yes, water being absorbed into a sponge is a physical change because the water molecules are simply being taken up into the empty spaces within the sponge's structure. The water molecules do not undergo a chemical reaction that would alter their chemical composition.
Sponges provide a protected environment for algae to live within their tissues, while algae produce food through photosynthesis that benefits the sponge. The algae also help with waste removal by consuming the sponge's metabolic byproducts. This mutually beneficial relationship is called symbiosis.
