This section focuses on the use of light microscopes to observe cell structures, particularly in onion skin cells. The cell biology microscopy practical GCSE is a fundamental experiment in biology education.
Definition: Light microscope - An optical instrument that uses visible light and lenses to magnify small objects, allowing the observation of cellular structures.
The practical involves the following steps:
Example: Students are expected to identify and label key cell structures such as the nucleus, cell wall, and cytoplasm in their observations of onion skin cells.
This practical helps students understand cell structure and develop essential microscopy skills, which are crucial for the AQA GCSE Biology microscope required practical method.
The investigating osmosis in potato tissue experiment GCSE is a key practical that demonstrates the concept of osmosis in plant cells. This experiment involves observing how potato tissue responds to different concentrations of sugar solutions.
Definition: Osmosis - The movement of water molecules from an area of high water concentration to an area of low water concentration through a selectively permeable membrane.
The practical procedure includes:
Highlight: This experiment helps students understand how osmosis affects plant cells and tissues, which is crucial for comprehending water movement in biological systems.
Students should pay attention to the controlled variables in osmosis potato experiment, such as the size of potato cylinders and the volume of sugar solutions used. This ensures the reliability and accuracy of the results.
This practical focuses on investigating the effect of temperature on the activity of the enzyme amylase. It is an essential experiment for understanding enzyme function and the factors that influence their activity.
Vocabulary: Amylase - An enzyme that breaks down starch into simpler sugars.
The practical involves:
Example: Students might observe that the reaction occurs fastest at around 40°C, demonstrating the optimum temperature for amylase activity.
This experiment helps students understand how enzymes work and how environmental factors like temperature can affect their function. It's a crucial part of the Biology Paper 1 required practicals BBC Bitesize resources often cover.
The food tests practical is designed to help students identify different nutrients in food samples. This experiment is crucial for understanding the composition of foods and the chemical tests used to identify various nutrients.
The practical involves testing food samples for:
Vocabulary: Qualitative reagents - Chemical substances used to test for the presence of specific compounds or elements.
The procedure includes:
Highlight: Each test produces a specific color change when the nutrient is present, allowing for easy identification.
This practical helps students understand the chemical composition of foods and develops their skills in using chemical tests to identify biological molecules. It's an important part of the AQA GCSE Biology required practicals that students need to be familiar with for their exams.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀

This app is phenomenal down to the correct info and the various topics you can study! I greatly recommend it for people who struggle with procrastination and those who need homework help. It has been perfectly accurate for world 1 history as far as I’ve seen! Geometry too!
