megasporangia's Usage Examples:

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

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

microphylls or megaphylls) bear either megasporangia and thus are called megasporophylls, or microsporangia and are called microsporophylls.

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

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

Flowering plants contain microsporangia in the anthers of stamens (typically four microsporangia per anther) and megasporangia inside ovules.

modified leaf and containing several sori bearing both megasporangia and microsporangia.

Female reproductive structures (megasporangia).

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

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

basal portion which contains placentas, ridges of tissue bearing one or more ovules (integumented megasporangia).

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

megasporophyll in hetersoporous plants, a modified leaf bearing one or more megasporangia.
