Modern Cell Theory and Cell Types
Ever wondered what everything living has in common? The answer is cells! According to Modern Cell Theory, all living things are made of cells, which are the basic units of structure and function in living organisms. Plus, new cells only come from cells that already exist.
There are two main types of cells. Prokaryote cells don't have a nucleus or membrane-bound organelles. Their DNA forms a single loop, and they're usually single-celled organisms like bacteria. Think of them as the simpler model of cells.
Eukaryote cells are more complex with a nucleus that houses their DNA shaped into chromosomes. These cells contain various membrane-bound organelles and are usually found in multicellular organisms like plants, animals, and fungi. Your body is made up of these types of cells!
Fun Fact: While structure refers to how a cell is built and what it looks like, function describes what the cell actually does - like its job description in the body!

Cell Organelles
Inside cells are tiny structures called organelles that work like mini-organs. Each has a special job to keep the cell running smoothly. The cell membrane acts like a security guard, controlling what enters and leaves the cell, while plant cells have an additional cell wall for extra support.
The nucleus is like the cell's brain, containing chromatin (DNA) with instructions for growth. Nearby, the nucleolus makes ribosomes, which build proteins. The cytoplasm is the jelly-like substance where all organelles float, supported by the cytoskeleton that gives the cell its shape.
Energy production happens in the mitochondrion, which creates ATP (energy) using oxygen. Plant cells also have chloroplasts that convert sunlight into food and energy. For transportation and processing, cells use the endoplasmic reticulum (both rough and smooth types) and the Golgi apparatus which packages and ships materials out of the cell.
Remember This: Your cells have specialized compartments just like your school has different rooms for different subjects. Each organelle has a specific job that helps keep you alive!

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.
