The diploid phase is the phase of the plant life cycle in which the zygote develops after fertilization. There are two phases in the plant life... Learn more about this topic: Alternation of Generations | Definition, Stages & Diagram
How does the sperm of an angiosperm reach the egg? What is the ploidy of a zygote produced by fertilization? How do seeds develop in angiosperms? How do seedless nonvascular plants reproduce? What is the result of recombination (crossing over) during meiosis?
Thus, human development starts with the process of fertilization, the process by which the male and female gametes unite and give rise to a zygote. This moment of zygote formation is considered to be the beginning or starting point of human development, and it takes place on the very first...
Growth is a widely used term in plant science and ecology, but it can have different meanings depending on the context and the spatiotemporal scale of analysis. At the meristem level, growth is associated with the production of cells and initiation of new organs. At the organ or plant scale...

SI is widespread and has multiple independent origins throughout the plant kingdom (see, for example, Raduski et al., 2012). However, it has proven difficult to explain how these recognition systems that require paired specificity of male and female components evolve and are maintained (...
Mechanisms that trigger transposition in hybrids are poorly understood, but it is well known that when two different genomes combine to form a zygote, it must respond to a massive shift in regulatory mechanisms due to this 'genomic shock'. TE TRANSPOSITION AND EPIGENETIC REGULATION Genomes have ...
Flowering plants are the most recent evolutionary adaptation to trees that live on land, having evolved about 145-100 million years ago, with conifers (gymnosperms) having evolved more than 350 million years ago. Seeds contain the zygotes of plants and serve to protect them for long periods...
After fertilization, a seed is formed encapsulating the embryo, while germination involves the emergence of the embryo from the seed as it begins to grow into a new plant. 6 ADVERTISEMENTComparison Chart Definition Fusion of gametes to form a zygote. Process of a seed developing into a new pla...
A zygote is the initial cell formed when two gamete cells merge, whereas an embryo is the next developmental stage after the zygote begins cell division.
