sperms commonly observed in fish from location III were also detected with lack of dynein arms in humans, by Baccetti et al.
The apically biflagellate
sperm of Coleochaete, formed in small but distinct antheridial cells, are consistent with sperm of land plants.
Dilution of 1 drop of CSF with 1 mL of distilled water will allow transformation of the organism within 1-20 hours from the ameboid to the biflagellate
Alexeieff proposed a new genus for questionable amoeboid forms, which he named Nagleria in honor of Nagler's work in identifying amoebae that pass through a biflagellate
Kessler (3) found that immobilized specimens of Dunaliella tertiolecta, a small green biflagellate
similar to Chlamydomonas, continued to orientate vertically under these conditions, but did so up to twice as rapidly when the cells were allowed to sediment in pure water.
Baccetti and Afzelius (1976) described 4 main types of sperm: primitive, modified, biflagellate
, and aflagellate.
