describe the levels of cellular structure in multicellular organisms as cells, tissues, organs and systems, using skin as an example.
In any organisation or company, there exist basic building blocks called systems, which each have a specific job to do within the company. Together these systems work together, to make the company function as a whole.
In the living world, systems also exist to help an organism function.
In plants, there are systems such as transport systems to allow substances to travel within the plant.
In mammals there are many systems such as the digestive system, which helps the mammal to break down food and obtain nutrition.
You will be examining many different systems to examine their roles and how together they ensure an organism’s survival.
