Mr 10 Departure Betwixt Eusporangiate As Well As Leptosporangiate Sporangium
On the footing of evolution the sporangia convey been classified yesteryear Goebel into ii categories: eusporangiate in addition to leptosporangiate.
Eusporangiate Sporangium: A large sporangium developing from several initial cells producing many spores. There are sometimes fused to cast synangia.
Leptosporangiate Sporangium: Small, specialized sporangia developing from a unmarried initial jail cellular telephone producing a small, definite number(<128) of spores. These oftentimes direct house inward a cluster (sorus) that is oftentimes covered yesteryear a flap of tissue known every minute an indusium.
Eusporangiate vs Leptosporangiate
Eusporangiate Sporangium:
1. H5N1 superficial jail cellular telephone divides yesteryear a periclinal wall forming an outer in addition to inner miss cell.
2. The sporogenous tissue is derived from inner miss cell.
3. The following cells are involved inward the formation of the sporangium wall in addition to the stalk.
4. The sporangium is large in addition to massive; the wall is several cells thick in addition to the spore content is high.
5. Primitive.
6.This type of sporangium is seen Psilotum, Lycopodium, Selaginella, Equisetum, Ophioglossum.
Leptosporangiate Sporangium:
1. H5N1 superficial jail cellular telephone divides yesteryear a periclinal wall forming an outer in addition to inner miss cell.
2.The sporogenous tissue is derived from the outer miss cell.
3. The sporangium wall in addition to the stalk, also every minute the spores are derived from the outer cell.
4. The sporangium is small, the wall is entirely 1 jail cellular telephone thick in addition to the spore content is low.
5. Advanced.
6. This type of sporangium is seen Marsila, Azolla, Fern, Salvinia.
