Mini Wiki 6a: Them Organelles Though

Hello! So last time on mini wikis we were looking at the plant cell as apposed to the animal cell. This time we’re going to do things a little differently and look at the organelles within cells. This Mini Wiki is going to come to you in 3 parts:

Mini Wiki 6a: An Introduction to Organelles

Mini Wiki 6b: Walk through of the organelles part 1

Mini Wiki 6c: Walk through of the organelles part 2

Look at me getting all organised! Let’s get started!

What is an organelle?

An organelle is a specialized subunit within a cell that has a specific function. Individual organelles are usually separately enclosed within their own lipid bilayers.

Why are organelles important?

Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. They carry out essential functions that are necessary for the survival of cells – harvesting energy, making new proteins, getting rid of waste and so on.

Why are organelles called organelles?

The world organelle is a diminutive from the Latin organum meaning“instrument,” in Medieval Latin  this means “organ of the body”.

Are there different organelles in each cell?

Yes, to some extent anyway. There are core organelles that are found in every cell, like the nucleus, then there are some organelles that are specialised to certain cells. Plant cells do have some different organelles compared to animal cells.

In conclusion, I hope this has given you a nice start to the world of organelles, next time we will be looking at each organelle in turn!
