| Each sporangiophore bears several sporangia, in which spores develop. |
| The genera are characterized by the sporangiophore and sporangial features and their relationship to and appearance of the rhizoid structures. |
| Each sporangiophore in Equisetum has 5 to 10 sporangia. |
| Growth response in distinction to the phototropic growth response, typically follows symmetrical illumination of the sporangiophore from above. |
| It inhibited zoospore release, cystospore germination, lesion formation, lesion expansion, sporangiophore development and sporangial production. |
| Each sporangiophore bears a number of fingerlike sporangia, which produce large numbers of thin-walled, green spores. |
