Function of elaters
WebAnother unique feature of liverwort spore dispersal is the presence of elaters, which contract and expand according to humidity to help propel spores. Note that after spore dispersal liverwort sporangia quickly wither away, … WebRhizoids perform a variety of functions in some mosses and liverworts, including water transport and adhesion to surfaces. A similar gene regulatory network governs the development of rhizoids in moss gametophytes and root hairs on vascular plant sporophytes' roots. Reference: Smith, A. (2024, June 17).

WebElaters are tubular cells with spiral thickenings and often help in spore release. This photo shows two spores and elaters of Fossombronia foveolata. Both spores are broken and exuding oily droplets. This photo … WebElaters are hygroscopic, meaning that they change shape and move in response to changes in moisture content. Elaters function in spore dispersal; as the sporangium dries out, the elaters twist out of the capsule, carrying spores with them ( Figures 3.11 , 3.12K ).
WebJul 7, 2024 · Elaters are the ribbon or tube like structures attached to the wall of spore. The elaters function is to increase dispersal because they push the spores out of the plant by absorbing moisture. How elaters are formed? Elaters are sterile diploid cells formed from archesporial tis- sue in the capsules of liverworts and hornworts. … WebSperm from the male reproductive organ (antheridium) travel through an aqueous environment to fertilize the eggs that are still retained in the female reproductive …

In mathematics, an elementary function is a function of a single variable (typically real or complex) that is defined as taking sums, products, roots and compositions of …
WebIn some mosses, rhizoids closely invest the stem among the leaf bases and perform a significant function in external water conduction and retention before its absorption by …
Webelaters are proposed for the elaters of two positions, that is, cluster-forming and free. In addition to free elaters, which are well known as spore dispersal organs of Hepaticae, a cluster of fixed elaters is formed in the capsule by some Hepaticae. In Metzgeriaceae, such a cluster of elaters is attached to the apex of the capsule; as the shark weight loss productWebThe remaining cells of the sporogenous tissue function as elater mother cells and, subsequently, become elongated, endowed with two spiral thickenings and become the sterile elaters (Fig. 6.18A, D). Unlike spores, the elaters are diploid cells and are hygroscopic, help in spore dispersal. shark wet dry floor cleanerWebWhat is the function of elaters? Step-by-step solution.

The function of the elaters is uncertain. Possibly, their expansion may assist in the dehiscence of the sporangia, or possibly their expansion and contraction may assist in spore-dispersal. shark westport maAn elater is a cell (or structure attached to a cell) that is hygroscopic, and therefore will change shape in response to changes in moisture in the environment. Elaters come in a variety of forms, but are always associated with plant spores. In many plants that do not have seeds, they function in dispersing the spores to … See more In the horsetails, elaters are four ribbon-like appendages attached to the spores.
