What is Polyembryony? What is Apomixis? Characteristics of Apomixis Characteristics of Polyembryony Differences Between and Apomixis Characteristics of Apomixis vs. Polyembryony Category Apomixis Polyembryony Offspring The offspring are genetically identical to the parent plant. This is because the embryos are produced asexually from the parent’s cells. The offspring can either be genetically identical or genetically … Read more
What is Polyembryony? Definition of Polyembryony Polyembryony is the development of multiple embryos from a single ovule or seed, resulting in several embryos within the same seed, which are genetically identical to each other but distinct from the parent plant. Types of Polyembryony Polyembryony can be classified based on various criteria including the source of … Read more
What is Apomixis? Definition of Apomixis Apomixis is a form of asexual reproduction in plants where seeds or embryos are produced without fertilization, resulting in offspring that are genetic clones of the parent plant. Characteristics of Apomixis Here is the Characteristics of Apomixis; Types of Apomixis Apomixis encompasses several distinct types of asexual reproduction in … Read more
What is Endosperm? Definition of Endosperm The endosperm is a tissue found in seeds of flowering plants that provides nourishment to the developing embryo. It is formed from the fertilization of a secondary nucleus by a sperm cell and can vary in structure, including nuclear, cellular, or ruminate types, depending on the plant species. Characteristic … Read more
What is Seed Dispersal? Types of Seed Dispersal Seed dispersal is a critical process for plant reproduction, ensuring that seeds are spread to new locations where they can germinate and grow. Various methods have evolved, each adapted to different environmental conditions and ecological interactions. The primary types of seed dispersal include: Agents of Seed Dispersal … Read more
What is Seed? Size and shape of Seed The size and shape of seeds exhibit considerable diversity, reflecting their adaptation to various ecological niches and functional requirements.
