Cellular Organization and Types

This section details the fundamental differences between eukaryotic and prokaryotic cells, focusing on their structural organization and genetic material. The text explains how bacterial cells form colonies and their potential effects on organisms.

Definition: Prokaryotic cells are simpler organisms lacking a true nucleus, typically ranging from 0.2-2μm in size.

Example: Bacterial colonies becoming visible to the naked eye when they grow large enough demonstrates prokaryotic cell multiplication.

Highlight: Eukaryotic cells encompass all animals, plants, fungi, humans, and protists, featuring more complex cellular organization.

Vocabulary: Plasmids - Small rings of DNA found in some bacterial cells.

Cellular Components and Structure

This section provides detailed information about the structure and function of animal and plant cells, emphasizing their key components and specialized features. The content covers essential organelles and their roles in cellular processes.

Definition: Ribosomes are cellular structures where protein synthesis occurs.

Example: Plant cells contain chloroplasts for photosynthesis, while animal cells lack this feature.

Highlight: Cell size varies significantly between animal cells 1030μm10-30μm and plant cells 10100μm10-100μm.

Vocabulary: Cytoplasm - A liquid gel where cellular chemical reactions occur.

Nerve and Muscle Cell Specialization

This section explores the specialized structures and functions of nerve and muscle cells, highlighting their unique adaptations. Nerve cells feature extensive mitochondrial presence in synapses and multiple dendrites for neural connections. Muscle cells are described in both striated and smooth varieties, with emphasis on their energy production capabilities.

Definition: Synapses are specialized junctions where nerve cells communicate through chemical transmitters.

Example: The transmission of nerve impulses from the spine to the big toe demonstrates how nerve cells function in the body.

Highlight: Muscle cells contain specialized proteins that enable movement through sliding mechanisms.

Vocabulary: Acrosome - A structure in sperm cells containing digestive enzymes necessary for egg penetration.

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.

Samantha Klich

Android user

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.

Best app on earth! no words because it’s too good

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

iOS user

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!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

Greenlight Bonnie

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

THE QUIZES AND FLASHCARDS ARE SO USEFUL AND I LOVE THE SCHOOLGPT. IT ALSO IS LITREALLY LIKE CHATGPT BUT SMARTER!! HELPED ME WITH MY MASCARA PROBLEMS TOO!! AS WELL AS MY REAL SUBJECTS ! DUHHH 😍😁😲🤑💗✨🎀😮

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
