Are coelentrates warm or cold blooded?
cold blooded. they live in the sea.
What is phylum coelentrates all about?
It's talking about jellyfish, coral, sea anemones 2. Coelenterates mean ''hollow Inside''
What is cindoblast?
It is the defensive organ present in Colenterates like Jelly fishes. If you handle these coelentrates with bare hands may even lead to death. The Cnidoblasts are also called Nematocysts or stinging cells.
How are sponges and coelentrates different?
Sponges are of the phylum porifera and are assymetrical invertebrates that have no true tissues due to a lack of cell specialization. Coelenterates are any of the phylum cnidariathat have radial symmetry and are invertebrates. Coelenterates include corals, sea anemones, jellyfish, and hydroids.
What are habitat of poriferans and coelentrates?
All poriferans and coelenterates live in water, most of them in sea water, but some in fresh water. Poriferans are bottom-dwellers. Coelenterates can be free-swimming, fixed to the bottom or live in colonies fixed to the bottom, depending on species and face of life.
Is an octopus a coelenterate?
Coelenterata is an obsolete term encompassing two animal phyla, the Ctenophora (comb jellies) and the Cnidaria (coral animals, true jellies, sea anemones, sea pens, and their allies).
Describe about the polymorphism in coelenterates?
iit is the phenominon in whichmore then two individuals are found in same specieces during its life cycle...as in obelia...wher polyps and medusa are formed...which have different function..polyps helps to feed so it is called nutretive zoods...and another one is medusa,which help in reproduction...so it is called reproductive zoods

What is metagenesis in coelentrates?
Metagenesis, also known as alternation of generations, is a reproductive phenomenon in cnidarians where individuals alternate between a polyp and medusa form throughout their life cycle. The polyp form is a sessile, cylindrical structure that reproduces asexually, while the medusa form is a free-swimming, bell-shaped structure that reproduces sexually. This alternating life cycle allows for genetic diversity and adaptation to different environmental conditions.
What are 4 ways an organism can reproduce asexually?
Four Ways that organisms reproduce asexually are as follows:-Binary Fission:- e.g. Paramecium, Euglena, AmoebaMultiple fission:- e.g. Amoeba during spore conditions, Euglena.Budding:- Sponges, Coelentrates (Hydra, Obelia)etc.Fragmentation:- Planarians (A type of aquatic worma like Annelids and Flat worms).
