Reproductive structures consisting of one or more photosynthetic cells surrounded by fungal hyphae are called Soredia.

Explanation:

Soredia and isidia are produced by lichens as reproductive structures.

Lichen is the symbiotic association of an alga or cyanobacterium with a fungus.

Symbiosis is a close association between organism in which both benefit each other.

In lichens the photosynthetic organism prepares food while fungus absorbs nutrients and water.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.
