SSS3 Biology: The Cell

The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known organisms. Cells are the smallest units of life, and hence are often referred to as the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology. Lesson summary Overview In this tutorial, you will learn 5 facts about cells. Including: 1. All living things are made up of cells. 2. Cells are made up of proteins and organelles. 3. Groups of cells form tissues and systems. 4. The main purpose of a cell is to organize. 5. The longest cells in the human body are the motor neurons. 6. Red blood cells carry oxygen around the body. The functions of the cell Cells provide six main functions. They provide structure and support, facilitate growth through mitosis, allow passive and active transport, produce energy, create metabolic reactions and aid in reproduction. Objectives Students will be able to Explain: Functions of the different parts of a cell; The differences between animal and plant cells; The differences between animal and plant cells; The chemical reactions within cells and the chemical reactions within cells.
