What would be the advantage to a sessile animal of producing a free-swimming larvae?

Advantage of sessile animal producing free-swimming larvae? To spread and not be concentrated in just one area.

What is free-swimming larva?

So, the correct answer is 'Parenchymula'

What is the purpose of a larval stage?

A larva sometimes functions as a food gatherer—in many species the larval stage occurs at a time when food is abundant—and has a well-developed alimentary system. It stores food so that the transformation to the adult stage can occur. Some larvae function in both dispersion and nutrition.

What is special about sponge larvae?

Sponge larvae are relatively uniform in their morphology. They are always ciliated, but there can be regions of longer cilia or areas that lack cilia completely. ... Larvae may lack spicules at release, but these may develop later during the free-swimming phase.

What is the function of Mesohyl?

The mesohyl acts as a type of endoskeleton, helping to maintain the tubular shape of sponges.

What is the job of the amebocyte?

The job of the amebocytes is to travel around distributing food and oxygen to the cells of the epidermis.

What is free swimming form of obelia called?

The planula is the free-swimming, flattened, ciliated, bilaterally symmetric larval form of various Cnidarian species. Planula attaches itself to the hard substrata and transforms into the young through metamorphosis.

Which of the following is the free swimming larva of Coelenterates?

Question : Characteristic free swimming larva of coelenterates is. Cysticercus.

What is free swimming ciliated larva of Coelenterata?

A planula is the free-swimming, flattened, ciliated, bilaterally symmetric larval form of various cnidarian species. The sperm and egg merge and form a planula larva, which matures inside the body of its mother. So, the correct answer is 'Planula'.

What are the special advantages of having an aquatic larval stage in the life cycle?

The presumed advantages of such larvae include the avoidance of competition for resources with adults, temporary reduct~on of benthic mortality while in the plankton, decreased likelihood of inbreeding in the next generation, and increased ability to withstand local extinction However, the direct~on of evolutionary ...

What is the biological importance of the larval stage during metamorphosis?

The larval stage enables an animal to avoid such hazards; it provides a mode of life and corresponding organization better suited to the smaller size of the newly emerged organism.

What is the difference between larva and larvae?

larva noun, plural larvae, adjective larval - An insect after issuing from the egg; in particular the second stage of an insect with complete metamorphosis. The term caterpillar is generally applied to the larvae of butterflies and moths (Lepidoptera).

Why does sponge absorb water?

Why do sponges absorb water? Sponges are made of loose fibers with lots of space between them. The holes between the sponge fibers absorb the water, and so the sponge material swells up with water. ... A damp sponge will absorb more water than a dry sponge as water molecules are highly attracted to one another.

Why sponges are animals?

Sponges may have been the first multicellular animals. ... Most sponges are hermaphroditic (male and female cells exist in one animal) and reproduce sexually by releasing spermatozoan into the water current to be carried to other sponges, where they interact with eggs. Sponges can also reproduce asexually.

What is a sponge larva?

Sponge larvae are relatively uniform in their morphology. They are always ciliated, but there can be regions of longer cilia or areas that lack cilia completely. There are two general types of sponge larvae, solid parenchymella larvae and hollow amphiblastula larvae. Sizes range from 50 pm to 5 mm in length.
