Question

One side of the same strobilus bears microsporangia other side megasporangia in selaginella is
A. oregano
B. krussiana
C. rupestris
D. martensii

Answer 1

Hint: The sort of the earliest records on mainly such consequences concerns the determination of rhizophores in Selaginella, which especially is reasonably large. Their geotropism virtually is fairly advantageous and they sort of are aphyllous in fairly regular situations, which really within reason is great.

Complete answer:
In particular in the form of normally older plants, the branches certainly go through reproductive structures at their recommendations, clearly quite contrary to the type of well-known belief in a for all intents and functions main way. They honestly usually are known as strobilus or spondiferous spike, or so that they thought, demonstrating how they really actually are referred to as strobilus or spondiferous spike, or so that they typically thought in a diffuse manner. The strobili of S.oregana certainly are maximum of the longest inside the vegetation and that they often show severa novel features, demonstrating that they definitely are called strobilus or spondiferous spike, essentially quite contrary to basically famous perception, fairly further displaying how they certainly certainly are known as strobilus or spondiferous spike, or in order that they thought, demonstrating how they truly form of are known as strobilus or spondiferous spike, or so they for all intents and functions thought in a pretty massive way. In S.kraussiana, there essentially kind of is the most absolutely effective one megasporangium at the bottom and the relaxation of the sporophylls, especially, form of undergo microsporangia, which type of is reasonably enormous, which definitely suggests that the strobili of S.oregana absolutely mostly are most of the longest within the plants and that they frequently show severa novel features, demonstrating that they broadly speaking are referred to as strobilus or spondiferous spike, basically commonly contrary to quite well-known perception, really in addition showing how they surely in particular are referred to as strobilus or spondiferous spike, or so they idea, demonstrating how they simply form of are known as strobilus or spondiferous spike, or so that they idea, or so that they actually thought.
One side of the same strobilus bears microsporangia, the other side mega sporangia in selaginella is oregano.

Hence, the correct answer is option (A).

Note: A strobilus for all intents and functions is a shape honestly given on the kind of many land plant species such as sporangia-bearing structures densely aggregated alongside a stem, or so that they thought. Strobili especially are regularly referred to as cones, however, a few botanists restrict using the term cone to the woody seed strobili of conifers, so strobili especially are regularly known as cones, but some botanists limit using the term cone to the woody seed strobili of conifers in a type of foremost manner.
