This resource covers the OCR syllabus on PLant transport- Translocation. Firstly it defines what translocation is and then further explains the key terms of source and sink regarding the translocation of sugars.
The booklet then further explains the key cells the make up the Phloem tissue, their components and functions.
It then goes on to explain the content of the sieve tubes and the reason why Sucrose is transported not glucose.
The resource then explains how translocation occurs using the mass flow hypothesis. It shows the key mechanism how Sucrose is loaded into the phloem using a co-transporter.
The booklet then shows with clearly labelled diagrams how sucrose is moved along the phloem. The finishing page focuses on the difficult 2021 Translocation question on how glucose produced in photosynthesis is translocated to parts of the plant where glucose is metabolised and stored.
This Biotechnology booklet
Introduces some key terms regarding Biotechnology and the many different uses of microorganisms in Biotechnology.
The introduction of Primary and secondary metabolites and when they are produced in the microbial growth curve.
There are some deep level thinking questions to challenge learners.
The booklet then goes on to explain some key Biotechnological processes and the microbes involved covering :
The production of food, pharmaceutical drugs, commercial enzymes and Bioremediation.
The booklet then introduces industrial scale fermenters and the key factors that can affect microbial growth.
The booklet contains picture of a standard fermenter and a power point resource that pupils can use to label and learn the key parts.
The Booklet then briefly compares Batch and Continuous culture and the key differences between them.
The last page contains the key terms of aseptic technique, asepsis and Contaminants and the results of what happens if contaminants enter in the fermenter and why asepsis is key to pure culture.
Lastly the challenges faced when scaling up small scale fermenters to industrial scale.
The booklet covers the difficult concept of how haemoglobin transports oxygen around the body and how the haemoglobin undergoes configurational change so that it bonds oxygen more easily after the first oxygen has joined.
The booklet then introduces Oxygen dissociation curves why they are sigmoid shape and how they are made including what the partial pressures means in terms of tissues in the body.
There are various amount of tasks in the booklet students are challenged to make a dissociation curve with some data and need to answer some key questions on what is happening at different parts of the graph in relation to partial pressure and haemoglobin shape.
The booklet then compares haemoglobin with both myglobin the oxygen storage molecule found in muscles and foetal haemoglobin. Both have questions on what these molecules do and where they are situated on the oxygen dissociation curve graph in relation to adult haemoglobin.
The booklet then introduces carbon dioxide transport in great detail and the three main methods it is transported in the blood.
The booklet then finishes on the Bohr effect and how carbon dioxide affects the oxygen dissociation curve and what happens when different carbon dioxide concentrations affect haemogobin loading and unloading.
This OCR Biology A level resource on Biotechnology and how Microorganisms make food:
This resource cover the production of:
Yogurt
Bread
Cheese
Wine and beer
Single cell protein (Quorn)
This lesson focuses on coronary heart disease and its components of diet that increase its risk:
Obesity
salt
Fats
Cholesterol make up of High dentisty Lipoproteins (HDLs) and Low density Lipoproteins (LDLs)
This booklet cover key methods that farmers are using to improve food production for the Human population.
The booklet covers :
Methods of making food production more efficient
In plans using selective breeding, chemical fertilisers, pesticides, herbicides etc
in animals using selective breeding and the use of antibiotics
This resource has everything needed to teach and learn about the heart at OCR A level.
The booklet starts at the basic structure of the heart and the main structures of heart anatomy both internal and external.
The Structure is explained using a simple gap fill activity to allow students to learn and complete the first page of the booklet.
The next is labeling the external and internal structures to allow students to orientate themselves.
The next part of the booklet explains the key stages in the cardiac cycle using a simple gap fill and then goes on to explain the cardiac cycle graph with clear labels of what is happening the pressure changes in the atria and ventricles.
The next part of the booklet explains the initiation of the cardiac cycle how the cardiac cells are myogenic and how the natural pacemaker SAN node triggers a wave of excitation over the atria and how the AVN node triggers ventricular contraction.
The last part of the booklet explains ECG graphs and what each part does and how to recognise abnormal ECG traces.
