How do plant and animal cells differ? Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria. However, plant cells and animal cells do not look exactly the same or have all of the same organelles, since they each have different needs.
A scientist is trying to identify an unknown cell. He determines that it has a nucleus and lysosomes. It also contains a cell membrane, but does not have a cell wall. What type of cell is the scientist most likely looking at?
An animal cell and a plant cell have several common features as well as a few key differences. In this video, we're going to spot the similarities and the differences between the two types of cells, and talk about their functions inside the cells.
So this is a very high level overview of cells, eukaryotic cells, I should say, but hopefully it also starts to show you some of the key distinctions between animal and plant cells.
Plants and fungi have a tough cell wall for protection and support, while animal cells can secrete materials into their surroundings to form a meshwork of macromolecules called the extracellular matrix.
If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell.

You, my friend, are made up of cells. Lots and lots of them. Jump in to learn more about prokaryotic and eukaryotic cells and the complex and beautiful structures inside them.
Key points: Mitochondria are the "powerhouses" of the cell, breaking down fuel molecules and capturing energy in cellular respiration. Chloroplasts are found in plants and algae. They're responsible for capturing light energy to make sugars in photosynthesis.
