Translocation in phloem refers to the process by which photoassimilates, primarily sugars, are transported over long distances within plants. This vital function occurs within the phloem, a type of vascular tissue responsible for distributing the products of photosynthesis from the sites of production to various sinks throughout the plant. The primary photosynthate transported by phloem … Read more
The transport of ions across the cell membrane is a fundamental process necessary for maintaining cellular homeostasis. The plasma membrane, acting as a selectively permeable barrier, allows certain substances to enter or leave the cell, ensuring proper balance between the intracellular and extracellular environments. This selectivity is crucial for the regulation of essential molecules such … Read more

What is Embryo Development in Plants? Development of the embryo (Embryogenesis) The development of the embryo in angiosperms, known as embryogenesis, is a complex and highly regulated process that transforms a diploid oospore (zygote) into a mature embryo. This process involves several key stages and can be categorized into different types based on the patterns … 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. This variability plays a crucial role in dispersal, survival, and germination strategies. Type of seed Seeds can be classified based on various criteria, including the number of cotyledons … Read more
