The key morphological feature that distinguishes Leptosporangiate ferns from Eusporangiate ferns is the number of cells involved in the formation of the sporangium.
In Leptosporangiate ferns, the sporangium is formed from a single cell, while in Eusporangiate ferns, the sporangium is formed from multiple cells. This difference is a fundamental feature used in the classification of ferns.
Information Booster:
Leptosporangiate ferns have sporangia formed from a single cell, whereas Eusporangiate ferns have sporangia derived from multiple cells.
This difference in sporangium formation is one of the main morphological characteristics used to distinguish the two types of ferns.
Leptosporangiate ferns are usually smaller and more common, while Eusporangiate ferns are typically larger.
Another characteristic of Leptosporangiate ferns is that their sporangium is often more specialized and more tightly controlled in terms of its dehiscence mechanism (spore release).
Eusporangiate ferns are more primitive and their sporangia are generally larger and produce more spores.
The distinction based on sporangium formation is crucial for taxonomic classification in pteridophytes.
