What is the Difference Between Homosporous and Heterosporous Pteridophytes

A main difference between homosporous and heterosporous pteridophytes is that homosporous pteridophytes produce only one type of spores, which are small in size while heterosporous pteridophytes produce two types of spores; the small microspores and the large megaspores.

Are Pteridophytes Homosporous or Heterosporous?

Difference between homosporous and hetrosporous

What do you mean by Homosporous and Heterosporous?

In Homosporous pteridophytes only one kind of spore is produced. In Heterosporous pteridophytes two kinds of spores are produced. ... The spores are equal in size in homosporous. The smaller spores are called microspores and the larger spores are called megaspores in heterosporous.

What are Heterosporous Pteridophytes?

A heterosporous life history occurs in some pteridophytes and in all seed plants. It is characterized by morphologically dissimilar spores produced from two types of sporangia: microspores, or male spores, and megaspores (macrospores), or female spores.

What is the difference between Homosporous alternation of generations and Heterosporous alternation of generations?

Solved: What is the difference between homosporous alternation ... Chegg.com. What is the difference between homosporous alternation of generations and heterosporous alternation of generations? ... Whereas gymnosperms undergo heterospory, that is, they produce two types of spores, the microspore and the megaspore.

What is Heterospory give two example?

Heterospory is the phenomenon of formation of two types of spores, i.e., smaller microspore and larger megaspore. ... Examples of heterospory are Selaginella, Salvinia and Marsilea, etc.

What is Homosporous condition?

hō'mə-spôr'əs, hŏm'ə-, hō-mŏs'pər-əs. Filters. Producing spores of one kind only that are not differentiated by sex. The spores of homosporous plants, such as horsetails and most ferns, grow into bisexual gametophytes (producing both male and female gametes).

What is meant by Homosporous?

(hɒˈmɒspərəs; ˌhəʊməʊˈspɔːrəs) adj. (Botany) (of most ferns and some other spore-bearing plants) producing spores of one kind only, which develop into hermaphrodite gametophytes.

Which one of the following is Homosporous?

Selaginella and Salvinia are homosporous.

What is meant by Heterosporous?

Heterospory is the production of spores of two different sizes and sexes by the sporophytes of land plants. The smaller of these, the microspore, is male and the larger megaspore is female.

Which Pteridophytes are Heterosporous in nature?

Selaginella, Salvinia, Marsilea and Azolla are heterosporous pteridophytes.

Does Azolla show Heterospory?

Heterospory is the most important evolutionary development in the vascular plants because it has ultimaetely led to seed development e.g.,selaginella, salvinia, azolla etc.

Which of the following is an example of Heterosporous Pteridophytes?

Complete Answer:

Selaginella and Salvinia are two examples of heterosporous pteridophytes.
