Spermatozoid-forming cells of Coleochaete scutata were found in packets of four arranged in concentric internal bands. Spermatozoids, which occur singly in antheridial cells, are spherical to ovoid, approximately 7 ,um long by about 3.9 ,um wide. As compared to relatively unspecialized zoospores, male gametes undergo a number of specialized cellular changes during development. The spherical nuclei and cytoplasm of mature spermatozoids are increased in density. Posterior plastids are reduced and… 

SPERMATOGENESIS IN COLEOCHAETE PULVINATA (CHAROPHYCEAE): SPERM MATURATION 1

TLDR
It is proposed that the large complex, striated fiber which connects basal bodies in C. pulvinata has been evolutionarily reduced in the Charales and Phaeoceros sp.

THE ULTRASTRUCTURE OF MEIOSPORES OF COLEOCHAETE PULVINATA (CHAROPHYCEAE) 1

TLDR
In location, morphology and presence of callose, chamberwalls resemble “special walls” of land plants, they may represent a charophycean spore development preadaptation useful in the evolution of walled spores characteristic of land plant.

OCCURRENCE AND PHYLOGENETIC SIGNIFICANCE OF “SPECIAL WALLS” AT MEIOSPOROGENESIS IN COLEOCHAETE

TLDR
Within germinating zygotes of Coleochaetepulvinata, meiospores are individually surrounded by chamber walls which are ultrastructurally and chemically different from vegetative cell walls of the same species, suggesting that the charophycean green algal ancestors of land plants may have possessed spore development preadaptations influential in the evolution of walled spores, an important plant adaptation to terrestrial life.

Ultrastructural studies of spermatogenesis inAnthocerotophyta V. Nuclear metamorphosis and the posterior mitochondrion ofNotothylas orbicularis andPhaeoceros laevis

TLDR
Ultrastructural observations reveal that the spermatozoids of the hornworts Notothylas andPhaeoceros contain two mitochondria and not one as described previously, and spline elongation precedes nuclear metamorphosis in hornwort.

THE OCCURRENCE AND PHYLOGENETIC SIGNIFICANCE OF PUTATIVE PLACENTAL TRANSFER CELLS IN THE GREEN ALGA COLEOCHAETE.

TLDR
This first report of putative placental transfer cells in a green alga supports Bower's (1908) ideas concerning the origin of land plant sporophytes and alternation of generations.

Ultrastructure of the Blepharoplast and the Multilayered Structure in Spermatogenesis in Osmunda cinnamomea var. asiatica

TLDR
The ultrastructural features of blepharoplast and the MLS of the protoleptosporangiopsida fern, O. cinnamomea var.

SOMATIC CELL FLAGELLAR APPARATUSES IN TWO SPECIES OF VOLVOX (CHLOROPHYCEAE) 1

TLDR
The similarities in the flagellar apparatuses can be explained as a result of adaptation for efficient colonial motion in organisms with similar colonial morphology, and the differences suggest a wider phylogenetic distance than previously believed.

The flagellar apparatus of the zoospore of the filamentous green algaColeochaete pulvinata: Absolute configuration and phylogenetic significance

TLDR
The organization and absolute configuration of the entire flagellar apparatus of theColeochaete pulvinata zoospore is compared to swarmers of other green algae belonging to theCharophyceae sensu Stewart and Mattox and to bryophyte spermatids.

An ultrastructural re-examination of putative multilayered structures inTrentepohlia aurea

TLDR
It is proposed that increased attention to the details of MLS structure may be crucial to an understanding of the divergence of main lines of green algal evolution.

Ultrastructure and Differentiation in Chara (Fibrosa) IV. Spermatogenesis

TLDR
It is suggested that centriolar movement in mitosis may be only one example of everal morphogenic movements associated with microtubule organization; their unction is in flagella formation, and not in synthesis of spindle, manchette, or other ytoplasmic microtubules.

TLDR
Spermatogenesis in the charophyte Nitella has been followed in antheridia prepared for light and electron microscopy and an attempt is made to compare similarities between plant and animal spermiogenesis.

STUDIES OF SPERMATOGENESIS IN THE HEPATICAE V. BLEPHAROPLAST DEVELOPMENT IN MARCHANTIA POLYMORPHA

TLDR
Flagellar growth in Marchantia is postulated to involve a process whereby subunits or their precursors are elaborated by the MLS, translocated to the distal end of the flagellum and incorporated into the axonemal tubules.

The ultrastructure of spermatogenesis in Equisetum is described with particular reference to the origin and development of the multilayered structure (MLS) and nuclear metamorphosis. Simultaneously

Ultrastructure of the scale-covered zoospores of the green alga Chaetosphaeridium, a possible ancestor of the higher plants and bryophytes

TLDR
The ultrastructure of the zoospore supports the old theory that the ancestors of the higher plants may well be found among Coleochaete and its relatives, past and present.

STUDIES OF SPERMATOGENESIS IN THE HEPATICAE : II. Blepharoplast Structure in the Spermatid of Marchantia

TLDR
The blepharoplast in a young, developing spermatid of Marchantia polymorpha, is a composite structure consisting of two basal bodies and a subjacent narrow band of axonemal-type tubules that the authors have termed the "spline," of which the aforementioned tubules constitute the uppermost layer.

STUDIES OF SPERMATOGENESIS IN THE HEPATICAE: I. Ultrastructure of the Vierergruppe in Marchantia

TLDR
Spermatids of the liverwort Marchantia polymorpha were shown by analysis of thin-sections to contain a four-layered organelle, the Vierergruppe, lying between the flagellar bases above and a subjacent mitochondrial body, supersedes Dreiergruppe interpretation in most if not all of the bryophytes studied to date.

TLDR
The MLS of Trentepohlia aurea may represent a stage in the evolutionary development of the MLS of land plants and may be a useful character in phylogenetic studies.
