Question

What plant is Heterospory found in?

Answer 1

Hint: Heterospory is the production of those spores of the two different sizes and the sexes by the sporophytes of the land plants. Heterospory evolved during the Devonian from isospory independently in several plant groups: the club mosses, the arborescent horsetails, and progymnosperms.

Complete answer:
Heterospory is found in some members of cryptogams and every one members of seed producing plants. Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants. Heterospory is evolved from homospory as a neighborhood of the method of evolution.
Heterospory could be a phenomenon during which two sorts of spores are borne by an equivalent plant. These spores differ in size. The smaller one is understood as a microspore and therefore the larger one is understood as a megaspore. Heterospory is thus considered a crucial step in evolution because it may be a precursor to the seed habit.
A heterosporous life history occurs in some pteridophytes and seed plants. It's characterized by morphologically dissimilar spores produced from two sorts of sporangia: microspores, or male spores, and megaspores (macrospores), or female spores.
All bryophytes are homosporous and every one gymnosperms are heterosporous. Microspores and megaspores may be a characteristic feature within the life cycle of a couple of members of Pteridophyta and every one of spermatophytes. therefore the correct option is 'Pteridophyta, Spermatophyta.

Note:
Heterosporous plants are certain pteridophytes or seed plants. Heterosporous plants are those that produce two diverse kinds of spores. they're microspores and therefore the megaspores. These spores vary within the different size and therefore the shape and hence it's called because the heterosporous spores.
