ANATOMY

Detailed explanation-1: -All living things are made up of cells, which is the smallest unit that can be said to be alive. An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular).

Detailed explanation-2: -A cell is the smallest unit that is typically considered alive and is a fundamental unit of life. All living organisms are composed of cells, from just one (unicellular) to many trillions (multicellular).

Detailed explanation-3: -Living things are called organisms. All organisms are made up of cells. Cells are the smallest unit that can carry out all of the functions of life. These functions include taking up nutrients and water, getting rid of waste, getting and using energy, and interacting with the environment.

Detailed explanation-4: -All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures. In multicellular organisms, similar cells form tissues.

Detailed explanation-5: -Cells are the basic structures of all living organisms. Cells provide structure for the body, take in nutrients from food and carry out important functions. Cells group together to form tissues?, which in turn group together to form organs?, such as the heart and brain.
