A particular immune system cell produces thousands of antibodies per second for release into the body. What type of organelle would you expect to be very prominent within the cell

The rough endoplasmic reticulum

Explanation:

The rough endoplasmic reticulum (ER) is an organelle that has the main function of producing proteins for the cell.

Antibodies are a type of protein, so they are made by the ER.

Since the immune cell can rapidly produce antibodies, it must have a significant amount of rough ER to make the proteins.

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.
