Page 2: Stem Cells and Specialized Cells

This page delves into stem cell applications and specialized cell functions, covering therapeutic cloning and microscopy techniques. The content explores both practical and ethical considerations in stem cell research.

Definition: Therapeutic cloning involves using undifferentiated stem cells to treat medical conditions by injecting matching stem cells into patients.

Example: Stem cells can potentially cure paralysis by differentiating into new nerve cells in the spine, or treat leukemia by forming new white blood cells.

Highlight: Specialized cells have specific adaptations for their functions, such as sperm cells with numerous mitochondria for energy production.

Quote: "The use of stem cells is an ethical issue because the stem cells come from embryos which are then destroyed."

Stem Cells and Cell Specialization

This section covers the therapeutic applications of stem cells and their potential in medical treatments.

Definition: Stem cells are undifferentiated cells capable of developing into different cell types.

Highlight: Therapeutic cloning uses stem cells to treat various medical conditions, including potential treatments for paralysis.

Example: Stem cells matching a patient's tissue type are injected to minimize rejection risk.

Cell Division and Chromosomes

This section explains the process of cell division and the role of chromosomes in genetic inheritance.

Definition: Chromosomes are DNA-containing structures that carry genetic information.

Highlight: Human cells typically contain 46 chromosomes in pairs.

Vocabulary: Mitosis - the process of cell division resulting in two identical daughter cells.

Active Transport and Cellular Adaptations

This section details how substances move across cell membranes and cellular adaptations for efficient transport.

Definition: Active transport moves substances against concentration gradients using energy.

Example: Plant root hairs absorb mineral ions from soil using active transport.

Highlight: Single-celled organisms have advantageous surface area to volume ratios for efficient substance transport.

Principles of Organisation

This section explores how cells work together to form more complex structures.

Definition: Tissues are groups of similar cells working together for a specific function.

Example: Muscular tissue enables movement through contraction.

Vocabulary: Organ systems - groups of organs working together to perform specific functions.

Page 1: Cell Structure and Types

This page introduces the fundamental differences between eukaryotic and prokaryotic cells, along with detailed cell structures. Plant and animal cells are classified as eukaryotes due to their membrane-bound organelles and nucleus, while bacterial cells are prokaryotes with simpler organization.

Definition: Eukaryotic cells contain membrane-bound organelles and a true nucleus, while prokaryotic cells lack these features and contain a single DNA loop.

Highlight: All cells, regardless of type, possess basic structures including a cell membrane and cytoplasm.

Example: Plant cells contain unique structures like chloroplasts for photosynthesis, vacuoles filled with cell sap, and cellulose cell walls for strength.

Vocabulary: Organelles - specialized structures within cells that perform specific functions.

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.

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.

Basil

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 😍😁😲🤑💗✨🎀😮

Elisha

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
