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 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
