Such a behaviour is very similar to the production of zoospores which is so common in many filamentous algae. ❋ Various (N/A)
The zoospores or mobile spores of many algæ and fungi. ❋ Various (N/A)
Each cell of all the plants of this genus produces a large number of mobile cells -- zoospores. ❋ Various (N/A)
Fructification: by zoospores, either single or very numerous, and by resting spores formed in sporangial cells after the contents have been impregnated by the contents of autheridial cells of different forms. ❋ Various (N/A)
Multiplied by division and by the formation of new larger individuals out of the contents of individual conjugated cells; perhaps also by spores and zoospores. ❋ Various (N/A)
There were also spores and mycelial filaments of fungi, dirt, and zoospores. ❋ Various (N/A)
But, instead of the terminal cell being filled with the usual densely crowded cluster of dark green granules constituting the rapidly forming spore, it contained hundreds of actively moving, nearly transparent zoospores, _and nothing else_. ❋ Various (N/A)
The spores are large, and produce zoospores, or spores with hair-like tails ❋ Sutton And Sons (N/A)
It is true one may argue that the zoospores of certain cryptogamia exhibit similar movements; but do not these zoospores possess as much of an animal nature as do the spermatozoa? ❋ Various (N/A)
Fructification: zoospores produced from the cell contents of the filaments; resting spores formed from the contents of particular cells after impregnation by ciliated spermatozoids produced in distinct antheridial cells. ❋ Various (N/A)
Reproduced by zoospores formed from the cell contents and breaking out from the surface, or by motionless spores formed from the whole contents. ❋ Various (N/A)
-- Plants growing in the sea or in fresh water, filamentous, jointed, without evident gelatine (forming merely a delicate coat around the separate filaments) Filaments very variable in appearance, simple or branched; the cells constituting the articulations of the filaments more or less filled with green, or very rarely brown or purple granular matter; sometimes arranged in peculiar patterns on the walls, and convertible into spores or zoospores. ❋ Various (N/A)
The families are formed either of assemblages of coated zoospores united in a definite form by the cohesion of their membranes, or assemblages of naked zoospores inclosed in a common investing membrane. ❋ Various (N/A)
Sometimes biciliated minute cells are found; without any doubt they are zoospores derived from any algoid or fungoid species. ❋ Various (N/A)
Their contents (zoospores) are liberated, and quickly grow in the leaf, and soon permeate every tissue of the plant. ❋ Various (N/A)
Reproduction: by cell division, by the conversion of the cell contents into zoospores, and by resting spores, formed sometimes after conjugation; in other cases, probably, by fecundation by spermatozoids. ❋ Various (N/A)
Reproduction by zoospores formed of the whole contents of a cell, with a crown of numerous cilia; resting spores formed in sporangial cells after fecundation by ciliated spermatozoids formed in antheridial cells. ❋ Various (N/A)
By these methods the cilia are seen to be fine protoplasmic outgrowths of the cell (fig. 1) of the same nature as those of the zoospores and antherozoids of algae, mosses, ❋ Various (N/A)
-- Microscopic cellular fresh water plants, composed of groups of bodies resembling zoospores connected into a definite form by their enveloping membranes. ❋ Various (N/A)
Reproduced by division and by resting spores produced in sporangia formed after the conjugation of two cells and union of their contents, and by zoospores formed in the vegetative cells or in the germinating resting spores. ❋ Various (N/A)
