Leaf like structure in Pteridophytes that bear spores are called as __...
Explanation:
Sporangia in Pteridophytes:
- Sporangia are the leaf-like structures in Pteridophytes that bear spores.
- These structures are responsible for the production and release of spores, which are essential for reproduction in these plants.
Types of Sporangia:
- In Pteridophytes, sporangia are of two types: homosporous and heterosporous.
- Homosporous sporangia produce a single type of spore, while heterosporous sporangia produce two different types of spores - microspores and megaspores.
Structure of Sporangia:
- Sporangia are typically found on the underside of specialized leaves called sporophylls.
- The sporangia are often clustered together in structures called sori, which can be seen as dark dots or lines on the underside of fern leaves.
Function of Sporangia:
- The sporangia contain sporocytes, which undergo meiosis to produce haploid spores.
- These spores are then released into the environment, where they can germinate and develop into gametophytes.
Conclusion:
- Sporangia are essential structures in Pteridophytes for the production and dispersal of spores, which are crucial for the reproductive cycle of these plants.

Sporophytes bear sporangia in leaf like structures called sporophylls. Sporangia further ruptures to form spores that germinate into a gametophyte containing archegonium and antheridium.
