Top 2026 AQA GCSE Biology Paper 1 Predictions and Revision Guide

We know that you're aiming high, so we're here with our top predictions for your 2026 AQA GCSE Biology Paper 1 exam.

But before we dive in, the most important advice. These are predictions. They're not a guarantee. The only way to

be 100% prepared is to revise your entire specification. So, use this list as a smart way to focus, not replace

your study time. And please look after yourselves. A well-rested brain is a smart brain. Build breaks, sleep, and

fun into your timetable. Now, we have so much content on our website to help you, from predicted papers and free

comprehensive revision notes to our detailed blog posts giving all the information that you need about each

paper. So, head over to primrosekitten.com after you've watched this video to explore all our resources.

In this video, we are going to look at our predictions for the content in the following biology papers. Higher

separate science and higher combined science. Let's begin with our predictions for the

higher separate science biology paper one. Starting with cells and organels, you need to be able to identify and

describe the function of key organels in both the ukareotic cells, that's plant and animal, and the proarotic cells,

which is bacterial. And you need to know the crucial differences. Next, microscopy and aseptic technique. You

need to know how to use a microscope and you must be able to perform magnification calculations using the

formula. And you also must revise the safety protocol of aseptic technique to prevent contamination when culturing

microbes. Next, stem cells. Revise embriionic stem cells, adult stem cells, and plant stem cells. Understand their

potential uses in medicine, such as treating paralysis or diabetes, and the ethical considerations surrounding their

use. The next topic, mitosis. You'll need to understand the stages of mitosis and its importance in producing two

genetically identical daughter cells. Next, respiration. Know the two types. Aerobic requires oxygen yields lots of

energy. Anorobic occurs without oxygen producing lactic acid in animals or ethanol and carbon dioxide in plants

releasing much less energy. The next topic photosynthesis. Memorize the word and symbol equations.

You must understand limiting factors, especially how light intensity, carbon dioxide concentration, and temperature

affect the rate. You also need to think about proteins, lipids, and carbohydrates.

Understand the structure and function of these three main food groups. Know the small molecules that make them up and

how they are used by the body. You also need to know the food tests for each. Next, you need to know about enzymes and

know that enzymes are proteins that speed up biochemical reactions without being used up. Make sure to understand

the lock and key model, the concept of the active site, and how factors like temperature and pH affect enzyme

activity. Next, the digestive system. Revise the roles of the main organs and pay attention to the adaptations of the

small intestine such as villi for efficient nutrient absorption. Next, the structure of the heart. This

is a diagram favorite. You must know the four chambers, the role of the valves, and the function of the coronary

arteries in supplying the heart muscle itself. The next topic, treatment for heart disease. Revise common conditions

like coronary heart disease and the medical procedures used such as stances to open blocked arteries. Next, plant

tissues and transport. You need to understand the function of the xyllem and phum. Also, you need to be able to

label a leaf and explain how its structure including the palisade meaphil and stomata is adapted for

photosynthesis and gas exchange. Revise the environmental factors that affect transpiration rate. You also need to

know about pathogens and human defense. Know the four types of pathogens, bacteria, viruses, fungi, and protests.

and focus on the immune system. How white blood cells use fagocytosis and produce specific antibodies and

antitoxins to fight infection. You also need to know about plant diseases because plants get sick too. Revise

common diseases like rose black spot and the physical and chemical defense mechanisms plants use to protect

themselves. You should also revise cancer and non-communicable diseases. Understand that cancer is uncontrolled

cell division leading to benign or malignant tumors. Also revise common non-communicable diseases like diabetes

and the associated risk factors. And finally, you should revise drug trials. Know the rigorous testing process,

pre-clinical testing on cells and animals and clinical trials on humans, including the necessity of double blind

trials and placeos to ensure validity. Now let's look at our predictions for the higher combined science biology

paper one topics. Beginning with cells and organels. You need to get ready to compare and contrast. Know the different

organels and their functions in both ukareotic cells and proarotic cells. Also learn about microscopy and

magnification. You need to know how to use a microscope and you must calculate magnification. Remember the formula

image size equals actual size multiplied by magnification or I equals AM and make sure that you can convert units

correctly. The next topic is respiration and you need to make sure that you know the two types. Aerobic with oxygen is

efficient and anorobic without oxygen is less efficient producing lactic acid in animals or ethanol and carbon dioxide in

plants and yeast. Next, learn about photosynthesis. The classic. You must know the word and symbol equations and

the limiting factors, especially how light intensity, carbon dioxide concentration, and temperature affect

the rate. The next topic is pathogens. This is all about the four types, bacteria, viruses, fungi, and protests.

And you need to know examples of diseases for each and how they spread such as the air or water. and then the

basic ways that we can prevent transmission. The next topic, proteins, lipids, and carbohydrates. Understand

the structure and function of these three main food groups and know the small molecules that make them up and

how they are used by the body. And you also need to know the food tests for each. Make sure that you revise enzymes,

knowing that enzymes are proteins that speed up biochemical reactions without being used up. Also, you need to

understand the lock and key model and the concept of the active site and how factors like temperature and pH affect

enzyme activity. You need to know the digestive system. So, follow the food. Revise the main organs and their

functions making sure to detail the adaptations of the small intestine such as villi for maximum absorption.

Make sure to revise the structure of the heart because you need to be able to label the four chambers and major blood

vessels. And you must know the complete path of blood through the double circulatory system. So revise the

circulatory system and know the three types of vessels and their jobs. The arteries, the thick walls away from the

heart, the veins, the thinner walls, valves towards the heart and the capillaries, the one cell thick walls

for diffusion. Also make sure that you know treatment for heart disease. Revise common conditions like coronary heart

disease and understand the treatments that are used such as stances to open blocked arteries and how they work to

improve blood flow. Next, you're going to need to revise cancer and non-communicable diseases. You need to

understand that cancer is uncontrolled cell growth and you must know the difference between benign tumors that

stay in one place and malignant tumors which spread. also revise other non-communicable diseases like diabetes

and associated risk factors. And finally, you need to revise drug trials. You need to know the rigorous stages of

testing, preclinical testing on cells and animals and clinical trials on humans. And you must explain the need

for double blind trials and placeos to ensure reliable results. I know that's a lot of content, but
