Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division.

Great website it explains the difference between smooth ER and rough ER.

mitochondrion , membrane-bound found in the of almost all eukaryotic (cells with clearly defined nuclei), the primary function of which is to generate large quantities of energy in the form of adenosine triphosphate (ATP). Mitochondria are typically round to oval in shape and range in size from 0.5 to10 μm.

1) All organisms are made up of one or more cells and the products of those cells. 2) All cells carry out life activities ( require energy, grow, have a limited size). 3) New cells arise only from other living cells by the process of cell division.

All cells are made up of a semi viscous fluid called protoplasm, which is considered as the physical basis of life, for it controls all biochemical reactions of the cell. In fact it is the microcosm of life with many secrets not known to us.

I didn't realize cells were so complicated!

The cell structure are the building blocks of an organism.

We have been talking about cells being a unit of organization in biology. Let's look at the cell membrane and see how that membrane keeps all of the pieces inside. When you think about a membrane, imagine it is like a big plastic bag with some tiny holes.

All living organisms on Earth are divided into cells. The main concept of cell theory is that cells are the basic structural unit for all organisms. Cells are small compartments that hold the biological equipment necessary to keep an organism alive and successful.

The cell wall is the tough, usually flexible but sometimes fairly rigid layer that surrounds some types of cells. It is located outside the cell membrane and provides these cells with structural support and protection, and also acts as a filtering mechanism.

While cell membranes might be around every cell, cell walls made of cellulose are only found around plant cells. Cell walls are made of specialized sugars called cellulose. Cellulose provides a protected framework for a plant cell to survive. It's like taking a water balloon and putting it in a cardboard box.

I did not know that Red Pandas shared similar DNA with raccoons.

A sea horse and a leafy sea dragon almost have the same qualities as each other

I learned that a red panda has the same dna as a racoon

Before there was five classification systems there was two, plants and animals.

Accepted systems of classification have changed at a faster pace than it has taken species to evolve.

I didn't know that there were only 2 kingdoms before.

I learned that Carl Linnaeus was the guy who made up the classifications for organisms.

I learned That Carl Linnaeus created the classification system in the 18th century and now it's being used as the modern classification system.
