In this video, we look at the different tissues present in a plant. First we explore the tissues in a leaf and look at the functions of each tissue. We then explore meristem tissue.

In this video, we start looking at the factors that can change the equilibrium of a reversible reaction. We look at Le Chatelier's principle, focussing on concentration.

In this video, we look at how plants use the glucose produced in photosynthesis. This looks simple but you need to learn the details as it's a favourite with examiners.

In this video, we start the topic on organic chemistry. We look at how crude oil is formed and then look at hydrocarbon molecules, specifically the alkanes. We explore the general formula of alkanes and how this is used.

In this video, we explore the effect of temperature on the rate of a chemical reaction. This involves looking at the idea of activation energy, which we will see again in the video on catalysts.
