Animal Cell Structure
The animal cell is a fundamental unit of life in multicellular organisms. Its structure is adapted to perform various functions essential for survival.
Key components of an animal cell include:
-
Nucleus: This is the control center of the cell, containing genetic material (DNA) that directs all cellular activities.
-
Cell Membrane: A selectively permeable barrier that controls the entry and exit of materials into and out of the cell.
-
Cytoplasm: The gel-like substance within the cell where many cellular reactions occur.
-
Mitochondria: These are the powerhouses of the cell, responsible for aerobic respiration and energy production.
-
Ribosomes: Small structures that are the site of protein synthesis, crucial for cell growth and repair.
Vocabulary: Aerobic respiration - The process of breaking down glucose using oxygen to release energy.
Definition: Cytoplasm - The jelly-like substance inside the cell where many cellular reactions take place.
Highlight: The nucleus is often described as the "brain" of the cell, as it controls all cellular activities and contains the genetic information.
Fungal Cell Structure
Fungal cells share characteristics with both animal and plant cells, making them unique in the world of cellular biology.
Key features of a fungal cell include:
-
Cell Wall: Provides support and structure to the cell, similar to plant cells.
-
Nucleus: Contains the genetic material and controls cell activities.
-
Cell Membrane: Controls the movement of substances in and out of the cell.
-
Cytoplasm and Ribosomes: Present as in animal cells, supporting cellular reactions and protein synthesis.
-
Vacuole: Stores water and cell sap, similar to plant cells but typically smaller.
Example: The most common example of a fungal cell is a yeast cell, widely used in baking and brewing industries.
Vocabulary: Cell sap - The liquid contents of a cell vacuole, containing dissolved sugars, salts, and other substances.
Plant Cell Structure
Plant cells have several unique features that distinguish them from animal cells and allow them to perform specialized functions.
Key components of a plant cell include:
-
Cell Wall: Provides rigidity and support to the cell.
-
Chloroplasts: Site of photosynthesis, where light energy is converted into chemical energy.
-
Large Vacuole: Stores water and maintains cell turgor.
-
Nucleus, Cell Membrane, Cytoplasm, Mitochondria, and Ribosomes: These are also present, similar to animal cells.
Definition: Photosynthesis - The process by which plants use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar.
Highlight: The presence of chloroplasts in plant cells is a key difference from animal cells, enabling plants to produce their own food.
Bacterial Cell Structure
Bacterial cells are prokaryotic, meaning they lack a membrane-bound nucleus and other organelles found in eukaryotic cells.
Key features of a bacterial cell include:
-
Cell Wall: Provides structure and protection.
-
Cell Membrane: Controls the movement of substances in and out of the cell.
-
Cytoplasm: Contains ribosomes and other cellular components.
-
Plasmid: A small, circular DNA molecule separate from the main bacterial chromosome.
Vocabulary: Prokaryotic - Referring to cells that do not have a membrane-bound nucleus or other membrane-bound organelles.
Highlight: Unlike eukaryotic cells, bacterial cells do not contain a nucleus or mitochondria, which affects how they process genetic information and produce energy.
This overview of cell structures provides a foundation for understanding cell biology and is crucial for students studying Nat 5 Biology or preparing for Nat 5 Biology past papers. Understanding these cellular components and their functions is essential for grasping more complex biological concepts and processes.

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.

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.

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.

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.
