Bosons and Fermions
By definition, bosons are particles which obey Bose-Einstein statistics: when one swaps two bosons, the wavefunction of the system is unchanged.
Fermions, on the other hand, obey Fermi-Dirac statistics and the Pauli exclusion principle: two fermions cannot occupy the same quantum state as each other, resulting in a "rigidity" or "stiffness" of matter which includes fermions. Thus fermions are sometimes said to be the constituents of matter, while bosons are said to be the particles that transmit interactions (force carriers), or the constituents of radiation.
ADD:Some people divide matter into pure substances and mixtures. Pure substances are elements and compounds. Mixtures include homogeneous and heterogeneous mixtures. Some people divide matter into homogeneous matter and heterogeneous matter. Homogeneous matter includes pure substances and homogeneous mixtures (solutions). Heterogeneous matter is heterogeneous mixtures.

Matter is typically classified into two categories: pure substances and mixtures. Pure substances are further categorized as elements (composed of only one type of atom) and compounds (composed of two or more different types of atoms chemically bonded together). Mixtures, on the other hand, are combinations of two or more substances that are physically intermingled but can be separated by physical means.
The two ways of classifing matter are (1) On the basis of physical state as a solid, liquid or gas. (2) On the basis of chemical constitution as an element, compound or mixture.
1. By its physical state - solid, liquid or gas
2. By its chemical constitution - element, compound or mixture
Sprite is a liquid solution that is classified as a beverage, so it is considered a liquid matter.
A tree is classified as matter because it is made up of various elements such as carbon, oxygen, and water. While it does store and convert energy through photosynthesis, it is ultimately composed of physical substances.
Items classified as matter have mass, occupy space, and have physical properties such as color, shape, and texture. Matter is made up of particles called atoms and molecules that interact with each other through physical and chemical processes.
Fluids.
The two categories of forces are contact forces, which occur when two objects are physically touching, and non-contact forces, which act between objects that are not in direct physical contact.
