Transport Across Cell Membranes Mindmap
Active transport and diffusion are crucial processes in cellular biology, governing how substances move across cell membranes. This summary explores their key differences, the effects of osmosis on plant and animal cells, and the structure and function of the cell membrane. Diffusion vs active transport in cells examples are provided to illustrate these concepts, along with detailed explanations of osmosis and its impact on different cell types.

This page provides a comprehensive overview of the various mechanisms of transport across cell membranes, focusing on passive and active transport across cell membranes. It illustrates the key differences between diffusion, osmosis, and active transport, along with their effects on plant and animal cells.
Definition: Diffusion is the movement of molecules down a concentration gradient from high to low concentration, requiring no energy input.
Example: Carbon dioxide diffuses out of cells from a higher concentration inside the cell to a lower concentration outside the cell.
The page explains that glucose and oxygen diffuse into cells from a higher concentration outside to a lower concentration inside, demonstrating the principle of passive transport.
Definition: Active transport involves the movement of molecules and ions from a lower concentration to a higher concentration, requiring energy input.
The document provides detailed illustrations of how osmosis affects both plant and animal cells:
Example: Animal cells placed in a solution with higher water concentration compared to their cytoplasm will gain water, swell up, and potentially burst.
Vocabulary: Turgid refers to the swollen state of a plant cell when it's full of water.
Vocabulary: Plasmolysed describes the state of a plant cell when it has lost water and the cell membrane has pulled away from the cell wall.
The page also describes the structure of the cell membrane:
Highlight: The cell membrane is composed of a phospholipid bilayer and is selectively permeable, allowing only small and soluble molecules to cross.
Definition: Osmosis is defined as the movement of water molecules from a higher water concentration to a lower water concentration through a selectively permeable membrane.
This comprehensive overview provides essential information for understanding the difference between passive and active transport across cell membranes, making it an invaluable resource for students studying osmosis and diffusion in cell membrane transport biology.

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!

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.

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!
