Ever wondered what makes cells different from each other? The biggest difference is whether they have a nucleus or not. Eukaryotic cells have a membrane-enclosed nucleus, while prokaryotic cells don't have a nucleus at all.
Size is another major difference. Eukaryotic cells are much larger than prokaryotic cells. Even the smallest eukaryotic cell (a red blood cell at about 8 micrometers) is larger than the biggest prokaryotic cell! Animal cells typically range from 10-30 micrometers, while plant cells can be even bigger at 10-100 micrometers.
Why such a size difference? Eukaryotic cells are more complex and need extra space for all their organelles - tiny structures that work like miniature organs within the cell.
Fun Fact If you can see an organism without a microscope, it's made of eukaryotic cells! Plants, animals, fungi, and protists are all eukaryotes.
Eukaryotic cells have two main regions the nucleus and the cytoplasm. The nucleus usually sits in the center of the cell, while the cytoplasm is the jelly-like substance that fills the space around it. The cytoplasm holds organelles in place and allows materials to move through the cell.
Plant and animal cells are both eukaryotic, but they have some key differences. Plant cells have a rigid cell wall outside their cell membrane that gives them shape and protection. This cell wall stops plants from bursting when they absorb water. Animal cells only have a cell membrane.
Another difference is that animal cells have centrioles used during cell reproduction, while most plant cells don't. Plant cells also form a cell plate as the cell wall develops during the final stage of cell division.
Remember The cell membrane is found in both plant and animal cells, but only plant cells have the extra protection of a cell wall!
Plant cells have some special organelles that animal cells don't. The central vacuole is a large storage container primarily used to store water, but it can also hold nutrients. This vacuole is crucial because it helps plants stay rigid and upright.
Plants stand tall thanks to turgor pressure - when water in the central vacuole pushes against the cell walls making them rigid. When plants have plenty of water, turgor pressure increases. Without enough water, plants lose turgor pressure and begin to wilt.
Another special feature of plant cells is chloroplasts. These organelles are the food factories of the plant, creating energy through photosynthesis. Any cell that performs photosynthesis will contain chloroplasts.
Try This Next time you see a wilted plant, water it and check back in a few hours. You'll see turgor pressure in action as the plant stands upright again!

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!

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!
