In cell biology, abscission refers to the separation of two daughter cells at the completion of cytokinesis. A plant will abscise a part either to discard a member that is no longer necessary, such as a leaf during autumn, or a flower following fertilisation, or for the purposes of …

The meaning of ABSCISSION is the act or process of cutting off : removal.

Abscission is a natural, well-organized, and coordinated process that allows aerial organs to separate from the plant body by breaking down cell walls and modifying cell-to-cell adhesion at abscission zones.

Abscission is a process that initiates the removal of a part of plant following the formation of a protective layer or scar tissue that prevents the entry of pathogen and protects the inner tissues from desiccation.

Aug 9, 2024 · Abscission refers to the natural separation of plant structures from their parent plants, regulated by external environmental signals or internal factors such as stress and aging.

Jan 19, 2021 · In botany, abscission is the normal separation of a plant part or organ. It occurs to separate a plant part or organ that may no longer be necessary. For instance, leaf abscission is the normal shedding of an old leaf at the base of the petiole such as that occurs during autumn.

Apr 23, 2018 · Abscission, from the Latin words ab (away) and sciendere (to cut), is a tightly controlled cellular progression that occurs at given developmental stages during the lifespan of a plant and ensures that plants can shed organs when they are no longer required – such as flowers after pollination or senescent leaves in the fall – and also as a way o...

Detachment of the older (rather senescent) leaves or leaf fall is a common phenomenon in plants and is called as abscission of leaves.

ABSCISSION definition: 1. the separation or falling off of part of a plant: 2. the separation or falling off of part of a…. Learn more.

Jan 23, 2024 · Plant organ abscission, a fundamental biological phenomenon, is a physiological process in which the leaves, flowers, fruits, seeds or branches of a plant are separated from the parent body. Plant organ abscission occurs at a specific site, the abscission zone (AZ), which is generally established at the time of organ formation (Lee 2019).
