~Vacuole~
• The word 'vacuole' is derived from the Latin word 'vacuus', which means 'empty'.• Vacuoles are found in the cytoplasm of both plant and animal cells.
• They have their own plasma membrane that controls what substances enter and leave.
• Vacuoles create hydrostatic pressure to help with the growth of plants.
• There are usually one large vacuole in plant cells and multiple smaller vacuoles in animal cells.
• They can break down waste and other excess substances that the cell doesn't need.What do they store?
• Water• Waste
• Proteins
• Lipids
• Carbohydrates
• Chemicals (in plant cells)
Summary
Vacuoles are one of the organelles found in all eukaryotic cells. They are best adapted for the function because of their plasma membrane that lets substances in and out. This organelle can fill up to 90% of the cell because they have the ability to expand and contrast based on how much they are needed to store. Vacuoles keep the cell hydrated and allow for it to survive in order to reproduce. I was surprised when I learned that vacuoles have their own plasma membrane. This surprised me because until now, my past science teachers have implied that the plasma membrane is only located on the outside of the cell.

I really like the set up of your blog post, its short and sweet which is very helpful when studying. I think it is also interesting that the vacuole has their own plasma membrane, I also didn't know that they stored proteins and lipids. I really liked how you put where the word vacuole is derived from because thats a good way to memorize. I think that you could've added that vacuoles help maintain homeostasis in cells but other than that i really enjoyed reading your post!
ReplyDeleteI like how you cut out the fluff and you got straight to the point. It keeps it short which is good for studying, especially when you have a lot of topics to study. Its good to know that the vacuole has their own plasma membrane because we learn that it is on the outside of the cell.
ReplyDeleteI like how you really summed up what a vacuole is in a short and informational way. I also did not know that a vacuole had a its own plasma membrane because I thought it was only on the outside too. I think one thing you could have added was maybe a picture of a vacuole in a cell.
