The asexual cells are termed tetraspores on account of the usual occurrence of four in each sporangium.
2
The outer walls of the sporangium now become hard, and the whole falls off as a seed.
3
Aplanospores would seem to represent zoospores arrested in their development; without reaching the stage of motility, they germinate within the sporangium.
4
The spores are formed in a manner very similar to those of the mosses, and are set free by rupture of the sporangium.
5
From each locule of a plurilocular sporangium there is set free an oosphere, which, being furnished with a pair of cilia, swarms for a time.
Usage of sporangia in inglês
1
The full developed plant is termed sporangia, and seeds are called spores.
2
On the leaves of this generation arise the sporangia which contain the spores.
3
The sporangia were very red and beautiful, but they showed no double cell wall.
4
In the perfectly mature sporangia, the sporidia have a dark brown color (mykophaein).
5
The sporangia are never spherical, but always flat.
6
Also some colorless sporangia, and spores abundantly present.
7
Pollen, Cosmarium, Leptothrix, Gemiasma, old sporangia, spores many.
8
The asexual cells are immotile spores arising in fours in sporangia from superficial cells of the thallus.
9
True reproduction of the asexual kind occurs, however, in the formation of sporangia, particularly in the Chamaesiohonaceae.
10
The sporangia may be terminal or intercalated.
11
Some large white sporangia filled with spores.
12
Paola Birdsong still shepherded the sporangia torus.
13
Many minute algæ, but two sporangia of a pale pink color; another variety of color of gemiasma.
14
Urine; amyloid bodies; spores; no sporangia.
15
Dried red sporangia of G. rubra.
16
In these cases, however, the potential gametes may, failing conjugation, germinate directly, like the zoospores derived from unilocular sporangia.
