- Plant embryonic development - Wikipedia
Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo This is a pertinent stage in the plant life cycle that is followed by dormancy and germination [1] The zygote produced after fertilization must undergo various cellular divisions and differentiations to become a mature embryo [1] An
- Developmental and genomic architecture of plant embryogenesis . . .
Abstract Embryonic development represents an important reproductive phase of sexually reproducing plant species The fusion of egg and sperm produces the plant zygote, a totipotent cell that, through cell division and cell identity specification in early embryogenesis, establishes the major cell lineages and tissues of the adult plant The subsequent morphogenesis phase produces the full-sized

The zygote ultimately divides to produce the mature embryo, the ovule develops into a seed, and the ovary that contained one or more ovules develops into a fruit A typical seed contains a seed coat, cotyledons, endosperm, and a single embryo The development of the embryo occurs through a process called embryogenesis
- Plant development - Zygote, Embryo, Seedling | Britannica
Plant development - Zygote, Embryo, Seedling: In vascular plants embryo formation, or embryogenesis, usually occurs within a few hours after fertilization, with the first cell division that cleaves the zygote, or fertilized egg, into two daughter cells Thereafter, rapid cell division provides the building blocks of the primary organs of the embryo sporophyte: the first root, first leaves, and
- Plant Embryogenesis - an overview | ScienceDirect Topics
The Unique Nature of Plant Embryogenesis Like animals, the initiation of plant embryogenesis is demarked by the fusion of the haploid sperm and egg cell, resulting in the formation of a diploid zygote, which then undergoes a series of divisions to produce a fully developed embryo

Let us make an in-depth study of Embryo After reading this article you will learn about: 1 Meaning of Embryo 2 Development of Embryo in Dicots 3 Development of Embryo in Monocots 4 Incompatibility 5 Special Modes of Reproduction Meaning of Embryo: After fertilization, the fertilized egg is called zygote or oospore which develops into an embryo The oospore before it actually enters into
- Plant embryogenesis: Current Biology - Cell Press
The key and defining step in plant embryogenesis is its initiation from a non-embryonic precursor cell This process naturally occurs when an egg cell is fertilized, transforming a haploid gamete into a diploid sporophyte This event most certainly triggers reprogramming of the cellular state, and sets in motion the subsequent steps of embryo development Strikingly though, embryo initiation
- What is a Plant Embryo: Definition and Anatomy
A plant embryo is the foundational stage of a new plant’s life, housed within a seed This tiny, undeveloped plant contains the rudimentary structures needed to grow into a mature organism Understanding the plant embryo helps explain how plants reproduce and perpetuate their species It is designed for survival and future development What is a Plant Embryo? A plant embryo is an immature
