This is true. A cell is the smallest unit of living matter, the basic unit of life. In multicellular organisms such as man, cells make up every tissue, organ, and organ system in the body. Man is organized in cells, tissues, organs and organ systems.
Cells work together in groups known as tissues. A tissue, be it plant or animal tissue, is defined as a group of similar cells working together to carry out a certain task.
Tissues in turn are grouped together to form organs and organs are organized to into organ systems to carry out specific functions in the body.
All these is possible because of the cell, the very basic unit from which all living matter is made.

This is the answer of your question.
<h3>WHAT Is COLDNESS ? </h3>
Cold is the presence of low temperature, especially in the atmosphere. In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to −273.15 °C on the Celsius scale, −459.67 °F on the Fahrenheit scale, and 0.00 °R on the Rankine scale.
<em><u>S</u></em><em><u>ince temperature relates to the thermal energy held by an object or a sample of matter, which is the kinetic energy of the random motion of the particle constituents of matter, an object will have less thermal energy when it is colder and more when it is hotter. If it were possible to cool a system to absolute zero, all motion of the particles in a sample of matter would cease and they would be at complete rest in this classical sense. The object would be described as having zero thermal energy. Microscopically in the description of quantum mechanics, however, matter still has zero-point energy even at absolute zero, because of the uncertainty principle.</u></em>
