2. molecule

2.1. A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge

3. Macromolecule

3.1. A macromolecule is a very large molecule, such as protein, commonly created by the polymerization of smaller subunits. They are typically composed of thousands of atoms or more. The most common macromolecules in biochemistry are biopolymers and large non-polymeric molecules.

4. Organelles

4.1. PLASMA MEMBRANE/ CELL MEMBRANE. Structure- a bilipid membraneous layer composed of proteins and carbohydrates. ... CYTOPLASM. ... NUCLEUS. ... 1. " ... RIBOSOMES. GOLGI BODY / APPARATUS. LYSOSOMES. MITOCHONDRIA.

5. cells

5.1. Cells are the basic building blocks of living things. The human body is composed of trillions of cells, all with their own specialised function. 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

6. Tissues

6.1. There are four main types of tissue: muscle, epithelial, connective and nervous. Each is made of specialized cells that are grouped together according to structure and function. Muscle is found throughout the body and even includes organs such as the heart.

7. Organs

7.1. Organs are the body's recognizable structures (for example, the heart, lungs, liver, eyes, and stomach) that perform specific functions. An organ is made of several types of tissue and therefore several types of cells.

8. Organsystem

8.1. An organ system is a group of organs that work together as a biological system to perform one or more functions. Each organ system does a particular job in the body, and is made up of certain tissues

9. Organism

9.1. an individual animal, plant, or single-celled life form.
