Are jelly fish sexual or asexual?
Stingrays are sexual, they mate during their matting season
How do polyp and medusae in coelenterates alternate with each other?
Polyp is a asexual form which has a cylindrical body just like hydra whereas the medusa form is sexual form and has an umbrella shape. In case of Aurelia, the adult is sexual form. Males and females are separate and after copulation the female releases eggs which develop into a hydra like structure called ephyra larva which is called polyp form. This larva by budding produces umbrella shaped medusa forms. Thus the asexual polyp form alters with the sexual medusa form. This alternation of generations is called metagenesis.
What is an polyp?
An ear polyp is a benign growth on or in the ear.
What is the relationship between a stationary polyp and free swimming medusa?
Some cnidarians have a life cyce wih an alternation of generations between asexual reproduction and sexual reproduction; while asexual reproduction provides a large increasing of (identical) individuals, sexual reproduction mantain a genetic pool variety.The generation supposed to reproduce asexually is polypoid; the generation supposed to reproduce sexually is medusoid.Tipically, medusae produce male and female gametes, which fuse together making zygotes; a zygote becames an egg from which hatches a free swimming larva called planula; the planula reaches the sea floor and developes into a polyp; the polyp then becames a strobila (segmented polyp), wich reproduces asexually by strobilation, segmenting itself and producing many ephyras, which can be released one at a time or all together at the same time; each ephyra maturates into an adult medusa, reaching the reproductive maturity.
Does a polyp have fluid in it?
No, a polyp is a growth of tissue and does not contain fluid. If there is any fluid associated with a polyp, it is typically due to inflammation or other underlying conditions.
A is the tube-shaped body form with a mouth surrounded by tentecles which serves as the asexual stage in some cnidarians?
It's a "polyp" bro.
In the Aurelia life cycle how are young medusas released?
In the Aurelia life cycle, young medusas, or jellyfish, are released from the polyp stage through a process called strobilation. During this phase, the polyp undergoes asexual reproduction, forming a stack of juvenile jellyfish, known as ephyrae. Once fully developed, these ephyrae detach and swim away, eventually maturing into adult medusas. This life cycle showcases the unique alternation between polyp and medusa forms characteristic of many jellyfish species.
Moss and ferns produce what during there asexual phase?
Polen
Which phase does a cell membrane pinches together?
Asexual reproduction
Does the sperm and the egg is necessary in asexual reproduction?
Asexual reproduction implies that no sperm or egg is required. Budding is a type of asexual reproduction, in which for example a coral polyp breaks off and begins a new colony, no sperm or egg.
Are jelly fish sexual or asexual?
Stingrays are sexual, they mate during their matting season
What is the juvenile form of a coral polyp?
The juvenile form of a coral polyp is called a "planula." This free-swimming larval stage is produced by adult corals through asexual reproduction or sexual reproduction. After a period of drifting in the water, the planula settles on a suitable substrate and undergoes metamorphosis to develop into a mature polyp, eventually contributing to the growth of coral reefs.
Is it true the polyp phase dominates in the animal life cycle in scyphozoa?
It is wrong as Medusa stage is dominent in Scyphozoa .

What is Erythrocytic schizogony?
It's the asexual phase in the malaria life cycle that takes place in the liver.
Describe the life cycle of a typical cnidarian Be sure to include the alternation of the polyp form with the medusa form?
The life cycle of a typical cnidarian involves an alternation between two main forms: the polyp and the medusa. The polyp is a sessile, asexual stage that attaches to a substrate, often reproducing by budding to form new polyps. In contrast, the medusa is the free-swimming, sexual stage that produces gametes through sexual reproduction. Fertilization results in a planula larva, which eventually settles and develops into a new polyp, completing the cycle.
