Can you describe metamorphosis in sponges?
Metamorphosis in sponges refers to the process where a free-swimming larva settles on a substrate and undergoes transformation into the adult sponge. During metamorphosis, the larva attaches itself to a surface, loses its cilia, and undergoes structural changes to develop into the adult sponge body plan. This process is essential for the larvae to transition from a planktonic stage to a sessile adult form.
A paramecium moves wit short hair-like extensions what are they called?
The hair-like extensions on a paramecium are called cilia. These cilia beat in a coordinated fashion to help the paramecium move through its aquatic environment.
Do blepharisma have cilia?
Yes, Blepharisma have cilia. Cilia are hair-like structures that help with movement and feeding in many protists, including Blepharisma. The cilia beat in coordinated patterns to allow the organism to swim and capture food particles.
What are treadlike structures extending from the cell membrane of paramecia?
The treadlike structures extending from the cell membrane of paramecia are called cilia. Cilia are hair-like structures that beat in a coordinated manner to help the paramecium move through its watery environment and help with feeding.
How are sponge larvae and collar cells similar to protozoans?
Sponge larvae and collar cells are similar to protozoans in that they are both single-celled or multicellular organisms that can exhibit similar feeding mechanisms, such as phagocytosis. They both possess specialized structures for ingesting food particles and transferring nutrients within the organism. Additionally, both types of organisms can be found in aquatic environments.
Does sponges a sponge get oxegyn from water?
Water is brought through cilia-lined pores into the hollow cavity of the sponge. As water passes through the pores, the cilia trap oxygen to breathe
What are sponge larvae?
Sponge larvae are the early developmental stage of sponges, aquatic animals belonging to the phylum Porifera. These larvae are typically free-swimming and are usually characterized as either parenchymula or amphiblastula, depending on the species. Upon settling, they undergo metamorphosis to develop into adult sponges, which are sessile and filter-feeding organisms. Sponge larvae play a crucial role in the reproduction and dispersal of sponges in aquatic ecosystems.
What is the locomotion of spongilla?
An adult sponge is sessile (anchored in place) and does not move.The adult sponge can reproduce asexually (via budding) or sexually utilizing sperm and ova.When reproducing sexually, the fertilized ova become larvae that have cilia that the larvae can use for locomotion.
Can you describe metamorphosis in sponges?

During metamorphosis, the larva attaches itself to a surface, loses its cilia, and undergoes structural changes to develop into the adult sponge body plan.

Does cilia help in cleaning the air that reaches the lungs?
Yes, cilia do help.
Sea anemone and sponge are sessile why are they group into animal?
Their larvae stages are motile stages.
How are colonies of corals and sponges formed?
Corals and sponges can both reproduce either sexually or asexually. In sexual reproduction eggs and sperm are broadcast into the ocean, where they meet and form a larvae. The larvae drifts around for a bit, and then settles to the bottom. If it is a suitable place, the larvae with turn into a new coral polyp or sponge. Then the coral or sponge reproduces asexually to form the larger colony.
How do protozoans move'?
Protozoans move with the help Pseudopodia, cilia and flagella. Pseudopodia - Amoeba Cilia - Paramaecium Flagella - Euglena
How do sponge depends themselves?
Spikes in the sponge help protect the sponge.
What is the name of the hair-like structures on a sponge cell that moves back and forth to help move water or nutrients or waste through the canal?
The hair-like structures on a sponge cell that move back and forth to help move water or nutrients or waste through the canal are called flagella. These structures create a current that allows for the circulation of water and the uptake of nutrients in sponges.
What are cilia and how are they used in the Venus Flytrap?
Cilia help the plant to tell whether it's consuming food or not.
A paramecium moves wit short hair-like extensions what are they called?
The hair-like extensions on a paramecium are called cilia. These cilia beat in a coordinated fashion to help the paramecium move through its aquatic environment.
