Grouping of what? Could you please provide more context or specify what you are referring to?
Plants with similar shaped leaves are more likely to belong to the same family, than otherwise. Are the leaves simple or branched, toothed or spikey, with hairs or not. And whether the veins are simple and parallel, or branched or joined. Are the leaves opposite each other on the stem, or on alternate sides. And similar properties.
A monophyletic group, or a clade, where all members share a common ancestor and include all its descendants.
Cladistics is a phylogenetic classification system that uses shared derived characters and ancestry as the sole criterion for grouping taxa. It aims to create monophyletic groups, where each group includes an ancestor and all its descendants.
The spindle is a structure found in eukaryotic cells that helps to organize and separate chromosomes during cell division. It is made up of microtubules and associated proteins that work together to ensure that each daughter cell receives the correct number of chromosomes.
The basis of departmentalization includes functions, products, geography, process, customer, and matrix. This organizational structure helps divide work to increase efficiency, coordination, and specialization within the organization. Each basis has its own advantages and is chosen based on the organization's goals and needs.
The basis of grouping animals is to classify them. This provides an easy and organized way to study and learn about a species.

It is called grouping data.

Blood grouping is highly effective. In a way, each year many lives are saved thanks to blood transfusions only because of the blood grouping system; knowing the blood to infuse into someone that has been donated that will react accordingly to the newer hosts body is a result of the blood grouping system.
