Gene expression and mutation lesson created in accordance to the NEW AQA Specification (9-1). NB: BIOLOGY ONLY-HT. Designed for higher ability class, although content can be adjusted to suit any ability. Includes: embedded videos and timers, slide animations, practice questions with answers on slides. AQA spec link: 6.1.5 Relevant chapter: B13 Genetics and reproduction. AQA Biology third edition textbook-Page 206-207. Specification requires students to know the following; (HT only) Mutations occur continuously. Most do not alter the protein, or only alter it slightly so that its appearance or function is not changed. (HT only) A few mutations code for an altered protein with a different shape. An enzyme may no longer fit the substrate binding site or a structural protein may lose its strength. (HT only) Not all parts of DNA code for proteins. Non-coding parts of DNA can switch genes on and off, so variations in these areas of DNA may affect how genes are expressed.

AQA Biology third edition textbook-Page 14-15 Specification requires students to know the following; Substances may move into and out of cells across the cell membranes via diffusion. Diffusion is the spreading out of the particles of any substance in solution, or particles of a gas, resulting in a net movement from an area of higher concentration to an area of lower concentration. Some of the substances transported in and out of cells by diffusion are oxygen and carbon dioxide in gas exchange, and of the waste product urea from cells into the blood plasma for excretion in the kidney. Students should be able to explain how different factors affect the rate of diffusion. Factors which affect the rate of diffusion are: •• the difference in concentrations (concentration gradient) •• the temperature •• the surface area of the membrane.

Students should be able to describe the function of stem cells in embryos, in adult animals and in the meristems in plants. Stem cells from human embryos can be cloned and made to differentiate into most different types of human cells. Stem cells from adult bone marrow can form many types of cells including blood cells. Meristem tissue in plants can differentiate into any type of plant cell, throughout the life of the plant. Knowledge and understanding of stem cell techniques are not required. Treatment with stem cells may be able to help conditions such as diabetes and paralysis

Active transport lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability separates class, although content can be adjusted to suit any ability. Includes: slide animations, practice questions with answers on slides, worksheet. AQA spec link: 4.1.3.3 Relevant chapter: B1 Cell structure and transport. AQA Biology third edition textbook-Page 20-21 Specification requires students to know the following; Active transport moves substances from a more dilute solution to a more concentrated solution (against a concentration gradient). This requires energy from respiration. Active transport allows mineral ions to be absorbed into plant root hairs from very dilute solutions in the soil. Plants require ions for healthy growth. It also allows sugar molecules to be absorbed from lower concentrations in the gut into the blood which has a higher sugar concentration. Sugar molecules are used for cell respiration. Students should be able to: •• describe how substances are transported into and out of cells by diffusion, osmosis and active transport •• explain the differences between the three processes.

Adapt and survive lesson created in accordance to the NEW AQA Specification (9-1). Designed for a higher ability class, although content can be adjusted to suit any ability.

AQA spec link: 4.7.1.4 Students should be able to explain how organisms are adapted to live in their natural environment, given appropriate information. Organisms have features (adaptations) that enable them to survive in the conditions in which they normally live. These adaptations may be structural, behavioural, or functional. Some organisms live in environments that are very extreme, such as at high temperature, pressure, or salt concentration. These organisms are called extremophiles. Bacteria living in deep sea vents are extremophiles.

AQA Biology trilogy edition textbook-Page 240-241 Students are required to know the following; Students should be able to: • describe the work of Darwin and Wallace in the development of the theory of evolution by natural selection • explain the impact of these ideas on biology. Alfred Russel Wallace independently proposed the theory of evolution by natural selection. He published joint writings with Darwin in 1858 which prompted Darwin to publish On the Origin of Species (1859) the following year. Wallace worked worldwide gathering evidence for evolutionary theory. He is best known for his work on warning colouration in animals and his theory of speciation. Alfred Wallace did much pioneering work on speciation but more evidence over time has led to our current understanding of the theory of speciation. Students should be able to describe the steps which give rise to new species. WS 1.1 The theory of speciation has developed over time

NB: This is a BIOLOGY (SEPARATES) ONLY lesson More about plant diseases lesson created in accordance to the NEW AQA Specification (9-1). Includes: slide animations, embedded videos, differentiated questions, answers have also been included within the slides. This resource is NOT suitable for combined science students. AQA spec link: 4.3.3.1 Relevant chapter: B5-Communicable diseases . AQA Biology third edition textbook-Page 92-93. Plant diseases can be detected by: • stunted growth • spots on leaves • areas of decay (rot) • growths • malformed stems or leaves • discolouration • the presence of pests. Identification can be made by: • reference to a gardening manual • taking infected plants to a laboratory to identify the pathogen • using testing kits that contain monoclonal antibodies. Plants can be infected by a range of viral, bacterial, and fungal pathogens as well as by insects. Knowledge of plant diseases is restricted to tobacco mosaic virus as a viral disease, black spot as a fungal disease, and aphids as insects. Plants can be damaged by a range of ion deficiency conditions: • stunted growth caused by nitrate deficiency • chlorosis caused by magnesium deficiency. Knowledge of ions is limited to nitrate ions needed for protein synthesis and therefore growth and magnesium ions needed to make chlorophyll.
