This lesson identifies and describes the functions of the reproductive organs of insect and wind pollinated flowers. Students then identify differences between wind and insect pollinated flowers and distinguishes between two different types of pollen grain and describes the process of pollination. The lesson then progresses to look at the differences between cross pollination and self-pollination. Fully resourced.

This is a fully resourced lesson on the process of meiosis with opportunity for students to model all phases in meiosis I and II. Exam practise included in the PPT and also the hard, medium and easy questions from Save My Exams.

This lesson starts with a recall of the differences between cross pollination and self-pollination and then the process of fertilisation. The lesson then covers the effects of cross and self-pollination. Fully resourced.

This lesson covers the conditions needed for seed growth and provides the opportunity for an investigation into these conditions. Exam questions for the whole plant topic included.

In this lesson students recall the process of mitosis and learn how it works. Students then learn how meiosis results in the formation of haploid cells. The lesson then progresses to explain how mitosis and meiosis are used in the formation of an embryo. Fully resourced. Exam questions included.

This lesson starts with a recall of what a ‘gene mutation’ is before moving on to learn how gene mutations occur. Lesson concludes with an explaination on how mutations affects the formation of the polypeptide.

In this lesson, students learn about transpiration in terms of water potential how water moves from the soil through a plant and into the air. They learn of the three pathways by which water is transported from soil to xylem and the three mechanisms by which water is moved from roots to leaves. Exam questions included.

in this lesson the students learn about what happens to the zygote after fertilisation. They then learn about the role of the placenta, umbilical cord, amniotic sac and fluid, and how nutrients and waste products are exchanged between mother and fetus (B). Fully resourced with exam questions.

This lesson starts with the different types of proteins that DNA codes for and how chromosomes are used to make proteins - transcription and translation. The lesson concludes with why not all genes are expressed at the same time. Fully resourced with videos and exam questions.

In this lesson, students learn about the stages of the menstrual cycle and the changes in the uterus and ovaries during the menstrual cycle. For higher tier students, they also learn of the role of hormones FSH, LH, progesterone and oestrogen in controlling the menstrual cycle. Lots of resources, activities and exam questions.

In this lesson, students learn about the role of chromosomes and the relationship between chromosomes, genes and DNA. They then learn of differences between genes and alleles. Differences between the X and Y chromosomes are learnt and how gender is inherited. Lesson concludes with a brief overview how genes code for proteins. (Transcription and Translation comes in another lesson). Fully resourced with videos and exam questions.

This lesson covers the factors that can affect the size of populations and the causes of natural selection.

This lesson covers how bacteria become resistant to antibiotics as an example of natural selection.

This lesson covers interpretion and constructing genetic diagrams to predict the results of dihybrid crosses that involve autosomal linkage. Some material has been adapted from other TES contributors and I have included additional material to support.

This resource covers everything concerning genetics and sex linkage, using genetic diagrams to predict and explain the results of monohybrid crosses.

This lesson covers interpretation and construction of genetic diagrams to explain and predict results of dihybrid crosses involving autosomal linkage and epistasis,

This resource builds on previous learning of dihybrid and monohybrid crosses to apply the Chi-square test and to use the Chi-square test to analyse the results of crosses (B-A).

This lesson covers the differences between structural and regulatory genes, and repressible and inducible enzymes. It progresses to cover genetic control protein production in prokaryotes using the lac operon , and the to describe and explain the use of transcription factors in plants.

This lesson provides students descriptions and explanations on the effects of temperature on enzyme action. Fully resourced with worked examples.

Fully resourced lesson which looks at pH as a factor of affecting reaction rates.
