cells
Cells are the main building blocks of tissues and organs. Different types of cells perform specific functions to support the structure and function of the tissues and organs in the body. These cells work together to form tissues, which then combine to create organs.
Organs are composed of tissues. Tissues are composed of identical cells, which are then made of proteins, lipids, carbohydrates and nucleic acids.
Proteins are the main building blocks for tissues including muscle, hair, nails, skin, eyes, internal organs, nerves, ligaments, tendons, cartilage and membranes. They are also the building blocks of cells, cellular membranes, organelles--all the way to the level of DNA and genes.
The four main parts of a multicellular organism are cells, tissues, organs, and organ systems. Cells are the basic building blocks, tissues are groups of cells working together, organs are groups of tissues with specific functions, and organ systems are groups of organs working together to perform complex functions.

Most of the structural components of an organism is made from proteins. Connective tissues like collagen and adhesion structures are made of proteins, usually more than one per unit, to connect and hold an organism together and provide structure.
A typical animal cell consists of a cytoplasm encased by a cell membrane. In the cytoplasm is:- a nucleus - stores genetic information- ribosomes - where proteinsythesis takes place- mitochrondria - for cellular respiration
Proteins
Proteins play a crucial role in the human body by serving as building blocks for tissues, enzymes for chemical reactions, and antibodies for immune defense.

The two types of organs are internal organs (such as the heart, lungs, and liver) and external organs (such as the skin, eyes, and ears). Internal organs perform vital functions within the body, while external organs are located on the outside of the body and help with sensory perception and protection.
Cells are the main building blocks of life. It is a part of the scientific theory that any living organism is made of cells.
