If you do have room for a small table (even if one side is up against a wall), there's not necessarily a need to have all the seating siting around it at once all the time, taking up needed space.

(Zoology) an organ of excretion in flatworms: a hollow cup-shaped cell containing a bunch of cilia, whose movement draws in waste products and wafts them to the outside through a connecting tubule.
Diagram of antheridium anatomy. An antheridium or antherida (plural: antheridia) is a haploid structure or organ producing and containing male gametes (called antherozoids or sperm). It is present in the gametophyte phase of cryptogams like bryophytes and ferns, and also in the primitive vascular psilotophytes.n bryophytes, the antheridium is borne on an antheridiophore, a stalk-like structure that carries the antheridium at its apex. In many gymnosperms and all angiosperms, the male gametophytes have been reduced to pollen grains and their antheridia have been reduced to a single generative cell within the pollen grain.
