How To Use Mother cell In A Sentence
-
The pollen cells are formed from mother cells by a process of cell division and subsequent setting free of the daughter cells or pollen cells by rejuvenescence, which is distinctly comparable with that of the formation of the microspores of Lycopodiaceæ, etc. The subsequent behavior of the pollen cell, its division and its fertilization of the germinal vesicle or oosphere, leave no doubt as to its analogy with the microspore of vascular cryptogams.

In the ovules of most sexual flowering plants female gametogenesis is initiated from a single surviving gametic cell, the functional megaspore, formed after meiosis of the somatically derived megaspore mother cell (MMC) 1, 2.

The so-called "Köpfchenbacterien" of older writers are simply bacterioid segments with a spore at one end, the mother cell-wall having adapted itself to the outline of the spore (fig. 4, F).

-
Where a transverse division places sister cells at the same level of the egg axis, they are usually numbered with reference to the chirality of the previous division: if the mother cell formed by a dexiotropic division, then the clockwise product of this cell's next division is given a superscript 2 and the counterclockwise product a superscript 1.

Maternal apomictic embryos develop from a somatic cell within the ovule or from an unreduced embryo sac derived from the megaspore mother cell (diplospory).
-
Well, you were mostly doing pathogenic bacteria, but it was a pity you didn't do any dimorphic prosthecate bacteria -- these are bacteria that have two different cell types -- non-motile "mother" cells and "daughter/swarmer" cells that swim off to eventually lose their motility and become mother cells themselves.

a sperm cell develops from a sperm mother cell
-
In this asymmetric cell division, the mother cell represents the soma and the daughter cell the germline.
-
Moreover, we found that daughter cells can clear themselves of damage by a polarisome - and tropomyosin-dependent polarized flow of aggregates into the mother cell compartment.

-
During sexual megagametophytic development (with the embryo sac as the megagametophyte and the egg cell as megagamete), a sub-epidermal cell of the nucellus tissue differentiates into a megaspore-mother cell which undergoes meiosis I and II to form four megaspores.
-
Zeospores; 2, 4, or multiciliated active automobile cells -- gonidia -- discharged from the mother cells or plants without impregnation, and germinating directly.

A detailed study of the fifth shoot-borne root showed that one lateral root mother cell develops in each two out of three successive merophytes.
-
It has a peculiarity in the fact that the hymenial cells, or the layer of mother cells, contained in the gills, change into a waxy mass, at length removable from the trama.
