Yes, columella is present in the zygospore of Zygomycota. The columella is a specialized structure that helps in the release of spores from the zygospore during reproduction.
The columella in a sporangium helps support the spore-producing structures, as well as aids in the dispersal of spores. It also plays a role in regulating the release of spores by controlling the opening and closing of the sporangium.
In mollusks, the columella is a central, supporting structure within the shell, particularly in gastropods and some bivalves. It serves as an anchor for the shell's whorls and provides structural integrity, allowing for the shell's coiled or spiral shape. The columella also plays a role in the attachment of the soft body of the mollusk to the shell, aiding in the organism's overall stability and protection.
Lucius Junius Moderatus Columella is the most important writer on agriculture of the Roman Empire. He was born in A.D. 4 and died in A.D. 70. His most notable work is 'De re rustica'
Capillitial threads are slender, thread-like structures found in some slime molds, assisting in spore dispersal. A columella is a central column-like structure found in certain fungi, such as mushrooms, supporting the spore-bearing layer. Both serve to aid in spore dispersal but differ in structure and function.
The proper name for a water snail is an aquatic snail.

Columella (is the part you see from the outside) Nasal septum (is the internal separating structure)
The 'black dots' (or 'brown dots') on the underside of fern fronds are reproductive structures. They are called sori(the singular is sorus). Within the sorus is a central column (columella), covered by a hard cover, the indusium (the cover you see and call the black dot). Sprouting beneath the indusium (ferns usually have indusia, but not always) and attached to the columella are sporangia, spore-bearing capsules. The fern is the spore-bearer, the sporophyte stage of the fern life cycle.
If you are talking about the structure just underneath the interior division of the nose, it's called the columella.
Rhizopus zygote has an elongated structure called the suspensor that connects the zygote to the point of attachment. Alongside the zygote, a structure known as the columella may be present, which aids in the formation of spore-producing structures.
According to SOWPODS (the combination of Scrabble dictionaries used around the world) there are 1 words with the pattern ---U---LA. That is, nine letter words with 4th letter U and 8th letter L and 9th letter A. In alphabetical order, they are: columella
