What is Fragmentation? Definition of Fragmentation Fragmentation is a form of asexual reproduction in which an organism or part of it breaks into smaller pieces, each capable of developing into a fully mature individual. General Steps of Fragmentation Fragmentation is a pivotal biological process characterized by its systematic progression through distinct stages. This method of … Read more
Many plants can reproduce genetically identical offshoots or clones of themselves through asexual reproduction. These offshoots then become independent plants. This is known as vegetative reproduction or vegetative propagation. Fragmentation is one way that vegetative propagation can occur. This means that a part of a plant can be regrown into a new plant. There are … Read more
