Rosette (botany) arrangement has been confirmed to improve survival, help water balance, or protect the plant from cold injury are "Espeletia schultzii" and "Espeletia timotensis", both from the Andes. The rosette form is the structure, the relationship of the parts, and the variations within it, as shown in the following study from a herbarium: As form then, "rosette" is used to describe plants that perpetually grow as a rosette and the immature stage of plants such as some ferns. Rosette (botany) In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit
Calyx of Held third postnatal weeks, around the time of hearing onset, the calyx of Held develops its characteristic, highly fenestrated (many openings) appearance. Fenestration results in the membrane being reduced to numerous small compartments, which increase surface area of the presynaptic cleft. As the membrane becomes increasingly pinched into these bulb-like structures, synaptic vesicles are further grouped into these spaces, resulting in an increased number of docked vesicles. To compensate for the available spaces in the calyx, glial cells with glutamate receptors and transports are used to fill open spaces, ensuring efficient uptake of glutamate in the synapse. This physical change in
