megaspores's Usage Examples:

These plants have two spore types, megaspores and microspores.

Microspores are land plant spores that develop into male gametophytes, whereas megaspores develop into female gametophytes.

species produce micro- and megaspores in the same sporangium, a condition known as homoangy, while in others the micro- and megaspores are produced in separate.

includes a megasporocyte (a cell that will undergo meiosis to produce megaspores).

Heterosporous plants that produced microspores in microsporangia and megaspores in separate megasporangia evolved independently in several plant groups.

The spores of seed plants are produced internally, and the megaspores (formed within the ovules) and the microspores are involved in the formation.

The best way to identify them is by examining the megaspores under a microscope.

egg cells), the gynoecium produces megaspores, each of which develops into a female gametophyte which then produces.

which meiosis will occur, resulting in the production of four haploid megaspores.

The megaspores can sometimes come to resemble that of either I.

echinospora, if the megaspores become eroded and bear projections.

These megaspores then develop into the haploid female gametophytes.

producing male and female gametophytes were of different sizes, the female megaspores tending to be larger, and fewer in number, than the male microspores.

Round white megaspores are about 480 micrometres (0.

The best way to identify them is by examining their megaspores under a microscope.

These plants produce microspores and megaspores, which give rise to gametophytes that are functionally male or female.

The spherical, white megaspores are 400 to 800 micrometers in diameter, and bear ridges that form honeycomb-like.

white megaspores are spherical and 490-670 micrometers in diameter.

echinospora, but with blunt spines and crests on the megaspores.

between the leaves, though these are not always present, and a surface of megaspores with tubercles, whereas I.

megaspores's Meaning':

larger of the two types of spore produced in heterosporous plants; develops in ovule into a female gametophyte
