__1. Explain the relationship between cells, tissues, organs and systems. __ A cell is a single unit of organism, which happens when many cells form together which then tissues are formed. When loads of tissues come together, organs are formed, and then when organs work with other things in our body, organs are formed.

__2. State, with examples that organs are a group of tissues that coordinate to do a specific job. __ Generally there is a main tissue called parenchyma and sporadic tissues. The main tissue s the one that is unique for its specific organ. The main tissue in the heart is called the myocardium, while the sporadic are the nerves, blood and connective. In single-cell organisms like bacteria, the functional analogues of organs are called organelles.

__3. Identify a variety of organ systems in animals and recall that they are made up of different organs with a special purpose working together. __ Animals bodies are made up of various body systems, which are groups of organs which work together to perform a function. These body systems include:
 * The reproductive system – the reproductive system allows animals to produce offspring
 * The nervous system – the nervous system allows animals to send, to receive and to process nerve and sensory impulses. The nervous system can be broken down into 3 parts, which include the central nervous system, the peripheral nervous system and the autonomic nervous system.

__Summary 1: __ The relationship between cells, tissus organs and systems is that cells join together as they cannot function on their own. The cells then form together to become tissue. Tissue then become organs. Organs work together to become an organ system e.g. the organs of the respiratory system consists of the nose, mouth, windpipe and lungs.
