megasporangia's Usage Examples:

plants there are two kinds of sporangia, termed microsporangia and megasporangia.

that produced microspores in microsporangia and megaspores in separate megasporangia evolved independently in several plant groups during the Devonian period.

sporophylls (whether they are microphylls or megaphylls) bear either megasporangia and thus are called megasporophylls, or microsporangia and are called.

Toward the center of each sorus and developing first are the megasporangia, each of which will produce a single large female megaspore.

sporophytes produce megaspores and microspores, which develop in the megasporangia and microsporangia.

spore are produced in different kinds of sporangia, these are called megasporangia and microsporangia.

The plants are accompanied by microspore massulae and megasporangia.

The megasporangia each produce a single megaspore.

microsporangia within the anther, and ovules (contained in carpels) contain megasporangia.

Female reproductive structures (megasporangia).

inner integument (which is integral to the formation of ovules from megasporangia) has been proposed to be by enclosure of a megasporangium by sterile.

formed from a modified leaf and containing several sori bearing both megasporangia and microsporangia.

types of spores occur: Microsporangia produce male microspores, and megasporangia produce female megaspores.

They bear sporocarps of two types, either megasporangia that are few in number (approximately 10), each with single megaspore.

placentas, ridges of tissue bearing one or more ovules (integumented megasporangia).

where flowers with anthers (microsporangia) and flowers with ovules (megasporangia) occur on the same sporophyte and "dioecious" where they occur on different.

The cones usually bear two kinds of sporangia: lobed megasporangia in the lower part of the cone which produce megaspores and simple microsporangia.

sporangia are located in the stamen anthers (microsporangia) and ovules (megasporangia).

megasporangia's Meaning':

a plant structure that produces megaspores
