Biology - Cell Theory, Metabolism and Plant Biology

This free online course will introduce you to cell theory, metabolism, and plant biology. You will begin by studying the six major groups of nutrients, the three types of carbohydrates, and the two types of digestion. The course also teaches you about growth and reproduction in various organisms, and you will then move on to learn about the five kingdoms into which all living organisms can be placed. 

The course then moves on to study cell theory, from its basic principles to the regulation of temperature in animals and the response cells have to environmental effects. You will learn how cellular processes enable complex organisms to survive in changing conditions and how cells group to form tissues and organs. You will also learn about cellular respiration, the role of membranes and the ways in which animal bodies can lose water.

The study of biology is important not just for those who are in the field of science but for everyone who wants to better understand their bodies, their resources, and potential threats that are present in the environment. It allows people to understand every organism present in the five kingdoms of living things. This course contains valuable knowledge for those who are interested in entering medical school, veterinary school, or other scientific graduate programs so make sure to start learning today.
