Hydroids and leptoids are found in bryophyte (mosses). They resemble and act like xylem and phloem----like vessel are to tracheids.
The vascular tissue in moss is called the hydroids and leptoids. Hydroids are responsible for conducting water, while leptoids are involved in nutrient transport. These tissues are simpler compared to the vascular tissues found in higher plants like ferns and flowering plants.
asexually I think
yes they exhibit polymorphism.. they have zooids and hydroids
Hydroids belong to the phylum Cnidaria.
Nudibranchs that eat hydroids will often take up sting cells from the hydroids and store them in the dorsal body wall. The sting cells can then be used to ward off predatory attacks.
Enemies of hydroids include a variety of marine organisms such as nudibranchs, which are known to feed on them, and some species of fish that may nibble on their tissues. Sea slugs and certain crustaceans can also pose threats to hydroids. Additionally, environmental factors like changes in water temperature and pollution can negatively impact their health and survival.

A palpocil is a minute soft filamentary process springing from the surface of certain hydroids and sponges.
spelloids. its due to the hydroids acting with the rooids to make spelliods.
Coelenterates that are found on Cornish shores include the sea anemones, true jellyfish and hydroids.
They are carnivores, feeding on: * small animals * small animal particles * protozoans
Um some good colonial hydro-ids would be like candy, fruit, and yo yew's.
