Pit connection
From Wikipedia, the free encyclopedia
In algal anatomy, a pit connection is a hole in the septum between two algal cells, and is found only in multicellular red algae[1] − specifically in the subphylum Eurhodophytina, except haploid Bangiales.[2] They are often stoppered with proteinaceous "pit plugs". By contrast, many fungi (only ascomycetes and basidiomycetes, as most other groups lack septa) contain septal pores − an unrelated phenomenon.[3]
