Which mechanism do sponges possess that makes a predator think twice before attacking it?
Sponges possess the defense mechanism of releasing toxins that make a predator think twice before attacking them. The toxic gases are considered dangerous and any predator would not want to attack a sponge.
Differentiate feeding mechanism of coelenterates and sponges?
Sponges smell of soap which is ok, also feeding mechanism is stupid, it's also very lazy. Just feed yourself or the animal yourself with the normal food.
Do sponges have hydrostatic skeletons?
Sponges do not have hydrostatic skeletons. Instead, they possess a simple body structure supported by a matrix called mesohyl, which contains various cells and skeletal elements like spicules and collagen fibers. This structure provides support and helps maintain the sponge’s shape, but it lacks the fluid-filled cavities characteristic of hydrostatic skeletons found in other animals. Thus, sponges rely on a different mechanism for structural support.
How do sponges diget their food?
Sponges are made of several cell types that each have certain functions. The ameobacyte (or ameoba-type cell) digests food that is driven to it by the collar cells, which each possess a flagellum
Do sea sponges have a diploblastic or triploblastic body organization?
spoges are diploblastic because they have radial symmetryone's having rad. sym. are diplo.and one's having bilateral are triploblasticThis is a true statement, but what we find in animal biology is that there are exceptions to most of the rules. Sponges, or the phylum Porifera do not have true tissues. They are metazoa at their cellular grade of construction, not eumetazoa. If you look at phylogenic tree, you will see that sponges are not directly related to cnidarians, which are radial symmetric and diploblastic. Some sponges are radial symmetric, however the class of sponges, demospongiae, have many species of sponges which have leuconoid body-plans, which are asymmetrical. These are mostly freshwater sponges. So therefore, sponges are not triploblastic or diploblastic, they are neither since they possess no true tissues.
Do sponges secrete toxins?
Yes, some sponges do secrete toxins as a defense mechanism against predators and to inhibit the growth of competing organisms. These toxins can vary in chemical composition and potency, and they may have potential applications in medicine, such as in cancer treatment. However, not all sponges produce toxins; many species have evolved different strategies for survival.
In what ways do sponges show evolutionary advancement compared to a colonial protozoan?
Sponges are multicellular organisms, whereas colonial protozoans are unicellular. This multicellularity in sponges allows for specialized cell types and division of labor, leading to increased efficiency and complexity in their structure and function. Sponges also possess differentiated tissues and exhibit more diverse body plans than colonial protozoans, demonstrating a higher level of evolutionary advancement.
Do octopus snails oysters and sponges all have a closed circulatory system?
No, octopuses have a closed circulatory system, while snails, oysters, and sponges do not. Snails and oysters possess an open circulatory system, where blood flows freely through cavities. Sponges, on the other hand, lack a circulatory system entirely, relying on the movement of water through their porous bodies for nutrient and waste transport.
Does sponge have symmetry?
Sponges are generally considered asymmetrical, meaning they do not possess any form of symmetry. However, some species exhibit a degree of radial symmetry, particularly in their body structure, but this is not consistent across all types. This lack of symmetry is part of what distinguishes sponges from more complex organisms that exhibit bilateral or radial symmetry. Overall, sponges are unique in their body plan and organization.
What is a sponges nervous system?
Sponges have no nervous systems, their middle jelly-like layers have large and varied populations of cells, and some types of cell in their outer layers may move into the middle layer and change their functions
Why Asconoid body design of sponges is not as efficient as Syconoid and Leuconoid?
Asconoid sponges have a simple, tubular body structure that limits the surface area available for filter feeding, making them less efficient than Syconoid and Leuconoid sponges. In contrast, Syconoid sponges have folded body walls that increase surface area, while Leuconoid sponges possess a complex network of chambers that further enhance feeding efficiency and water flow. This increased complexity allows for greater nutrient absorption and better adaptation to varying environmental conditions. Consequently, Asconoid sponges are generally less capable of thriving in competitive or nutrient-rich environments compared to their more advanced counterparts.
What are are not part of sponges?
Sponges, belonging to the phylum Porifera, do not have true tissues or organs, which differentiates them from more complex animals. They lack a nervous system, digestive system, and circulatory system, relying instead on the flow of water through their porous bodies for nutrient intake and waste removal. Additionally, sponges do not possess specialized structures like fins, limbs, or a centralized body plan, which are found in many other animal groups.
