Eukaryotic vs Prokaryotic Cells
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.

Inside Eukaryotic Cells
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 Cell Special Features
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!

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.
