In this lesson we have a look at the different types of nutrients that is essential for life and we focus on the inorganic nutrients that are essential for both plants and animals and what happens when there is a lack of these nutrients for organisms.
In this lesson we look at two of the main groups of organic nutrients; carbohydrates and lipids. We look at the different types of these organic nutrients and their structures as well as the function of these nutrients in living organisms.
In this lesson we look at proteins as a group of organic nutrients, their structure and the functions that proteins have in living organisms. We also take a close look at enzymes, how they function and the factors that can have an effect on the rate of enzyme function.
In this lesson we look at the different tests that can be performed to determine of food stuffs contain certain organic nutrients. We look at these tests for starch, glucose, lipids proteins and cellulose.
In this lesson we look at the two different nucleic acids that are found in living organisms namely DNA and RNA. We take a look at their structure and their functions. We also take a look at the different vitamins that are essential for living organisms.
In this lesson we take a look at the history of microscopy and the different types of microscopes. We look at the different components of light microscopes and how to calculate the actual size of objects that are seen through microscopes.
Chemistry of life: The movement of the cell membrane
In the lesson we take a closer look at the structure of cell membranes. We also delve into the different ways in which substances can move across these membranes and the processes involved in the movement.
In this lesson we look at the different graphs that can be drawn from our results obtained in investigations. We look at four different types of graphs including the bar graph, line graph, histograms and pie charts.
