The major functions of the skeletal system are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and blood cell formation.

There are trillions of cells in the animal body and each one is different depending on its function and type. Most animal cells have at least the three main parts: nucleus, cell membrane, and cytoplasm.

Blood has three main functions: transport, protection and regulation. Blood transports the following substances: Gases, namely oxygen (O2) and carbon dioxide (CO2), between the lungs and rest of the body.

Functions of Nucleus The main function of the cell nucleus is to control gene expression and mediate the replication of DNA during the cell cycle. It controls the hereditary characteristics of an organism. The organelle is also responsible for protein synthesis, cell division, growth, and differentiation.

The three parts of the cell theory are as follows: (1) All living things are made up of cells, (2) Cells are the smallest units (or most basic building blocks) of life, and (3) All cells come from preexisting cells through the process of cell division.

They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.

All cells have at least three common features: a cell membrane, cytoplasm and DNA. In addition, Cell Theory has 3 basic characteristics: All organisms are made up of one or more cell.

Structures within cells have individual functions, and in general, no matter the structure, these can be reduced to three essential jobs: A physical interface or boundary with specific molecules; a systematic means of shuttling chemicals into, along or out of the structure; and a specific, unique metabolic or ...
