Differbetween
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.

Difference between homosporous and hetrosporous
| Homosporous | Heterosporous |
|---|---|
| These type of pteridophytes are small in structure and cannot be separated by sex | These type of pteridophytes produce two types of spores and are separated by sex |
| Gametophyte is unisexual | Gametophyte is bisexual |
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 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 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 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 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 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).
Are bryophytes Heterosporous?
Bryophytes are not heterosporous. They are homosporous – which means they produce spore of only one kind.
Do Pteridophytes have alternation of generations?
Just as with bryophytes and spermatophytes (seed plants), the life cycle of pteridophytes involves alternation of generations. This means that a diploid generation (the sporophyte, which produces spores) is followed by a haploid generation (the gametophyte or prothallus, which produces gametes).
Which best describes the alternation of generations?
A gametophyte is a haploid phase best describes the alternation of generations.
Are Sporophytes haploid?
The sexual phase, called the gametophyte generation, produces gametes, or sex cells, and the asexual phase, or sporophyte generation, produces spores asexually. In terms of chromosomes, the gametophyte is haploid (has a single set of chromosomes), and the sporophyte is diploid (has a double set).
