Spore formation as a multi-cellular phenomenon includes a trade-off: cell divisions before sporulation increase the total number of spores formed at the end. In contrast, rapid spore formation leads ...

Spore formation: Spores are asexual reproductive bodies. A spore is covered by a hard protective coat to withstand unfavourable conditions such as high temperature & ow humidity.

Before sexual reproduction was established there ˜ were three stages:-The primal capacity for cell-division led on to spore-formation by vegetative cells, and that to spore-formation by special ...

Researchers have discovered an ancient plant species whose reproductive biology captures the evolution from one to two spore sizes -- an essential transition to the success of the seed and ...

By tracing the genomes of nine brown algal species, researchers have shed light on the ancient origins, remarkable stability, ...

A First Report on Pseudomeiotic Sporogenesis, a Type of Spore Reproduction by Which "Sterile" Ferns Produce Gametophytes Virginia M. Morzenti American Fern Journal , pp. 69-78 (10 pages) ...

The study, published in the journal Molecular Plant-Microbe Interactions, found that the fungus undergoes sexual reproduction early on in lesion formation, and this requires two individuals of ...

In Polytoma, however, the cytoplasm within the spores has to undergo several complex changes, leading ultimately to division of sarcode, formation of envelopes round the products of division, and ...

These structures contained spores, which are used in the reproductive cycle of plants. They’re tiny – between 70 and 200 microns across, or a strand to two strands of hair.
