WELCOME

Hello, and welcome to my blog! This blog is strictly about Organelles- what they are, where they are, and what they do- for my science project. Please, feel free to let me know if I have any mistakes or if you have any helpful ideas. Thanks for reading :)

8- The Cell Wall

The cell wall is like a "rubber band" around the plant cell, giving it the shape and support it needs. It is only in plant cells, around the very outside edge.

Picture:

My Example:

The cell wall is like a rubber band because it gives shape and support. It would have to be flexible enough to surround the cell to give it a unique shape, and strong enough and stable enough to support it.

7- The Cytoplasm

The cytoplasm is like a "jello" substance that fills up all empty spaces. It is located in both plant and animal cells, wherever there is no body or life-form.

Picture:

My Example:

I believe the cytoplasm is like jello, because jello is squishy and can fill up spaces. It's like if you cut a line in it, you can't see the line because the jello folds over and covers the hole, as if "re-stitching" itself. I think cytoplasm does that, too, so there are no empty spaces that would hurt the cell.

6- The Lysosomes

The lysosomes are like the "garbage disposals" of the cell. They break down and destroy the things the cell doesn't need. It is also called a "Suicide Sac". It is located in the cytoplasm of only animal cells.

Picture:

My Example:

The lysosomes destroy things in the cell (and if they leak, they could kill the cell- hence the name "Suicide Sac") so I used the garbage disposal for example. It destroys things it doesn't need, too.

5- The Golgi Apparatus

The golgi apparatus gathers and sends things, like wrapping a present and sending it, a "postal office". It is located in the cytoplasm of both plant and animal cells.

Picture:

My Example:

This picture represents how the golgi apparatus is like a post office. The FedEx vehicle is sent from the main headquarters out to deliver mail and packages.

4- The Mitochondria

The mitochondria (AKA the "power house") is like the "battery" of the cell. It breaks down food into energy that the cell needs. It is located in the cytoplasm of both plant and animal cells.

Picture:

My Example:

This picture shows what the mitochondria gives the cell- energy- in human form. A car needs a battery to run as a cell needs a mitochondria to run. Car:Battery::Cell:Mitochondria

3- The Cell Membrane

The cell membrane is like the "security" or "police" of the cell. It controls what enters and/or exits. Located around the outside edges, in both plant and animal cells.

Picture:

My Example:

You can only get through to a building or place (Ex: State Fair) by going through a gate, or security detail. Anything that wants in the cell has to go through the cell membrane.

2- The Nucleolus

The nucleolus is the "recipe book", I guess you could say, of the cell. It gives the recipe for protein to the ribosomes. Located inside the nucleus, it is in both plant and animal cells.

Picture:

My Example:

The nucleolus is needed to "feed" the cell, as chefs are needed to feed people. It's like if you were at a banquet, you would expect food, right? The nucleolus sends the recipe to the ribosomes, that make the food. So the nucleolus is like a recipe book.
