The Earth is like an animal cell.
The nucleus is the control center of a cell. The nucleus is the organelle that contains DNA and the DNA sends messages to the other organelles. The messages travel through the nuclear membranes.
The inner core is like the nucleus of a cell.
The Nucleus:
The core of the Earth is also like a control center. It has iron alloys in it that move around and cause the magnetic field around Earth. The magnetic field keeps the solar radiation and winds off of Earth. Without the field, the Earth's surface would be destroyed.
The inner core is like the nucleus of a cell.
The Inner Core:
How are both of these alike?
The core contains iron alloys in it just like the nucleus contains DNA. Both of these materials are extremely important and without them both the Earth and the cell would be complete chaos.These materials operate from within the nucleus or the core.
Severe weather is like a lysosome.
Lysosome:
A lysosome is an organelle inside the cell that contains digestive enzymes. Lysosomes are also known as suicide sacs. They destroy the bacteria that a white blood cell swallows and act as the stomach of the cell.
Storms occur all over the Earth in different forms. Tornadoes, hurricanes and tsunamis are all examples of storms. All of these storms are extremely destructive, and they destroy thousands of cities a year. This is tragic, but the buildings that are rebuilt are usually sturdier and better designed, so this was not all bad. They also destroy some things that aren't saf
Severe weather is like a lysosome.
Severe Weather:
Severe weather on Earth includes tornadoes, hurricanes, wind storms, and tsunamis. Each type of severe weather has something in common. It destroys. Every year thousands of cities are destroyed by storms.
Severe weather is like a lysosome.
Severe Weather:
How are both of these alike?

Lysosomes and severe weather both destroy. A lysosome destroys bacteria and severe weather destroys cities. Cities aren't bad like the bacteria that invades the body, but after a storm destroys a city, the bad building techniques that were used in the city will be shown.
The cell membrane is like the atmosphere.
The Cell Membrane:

The cell membrane is a protective layer that surrounds the cell and acts like a barrier. It separates the cell's contents from the outside environment. It is made up of a double layer of lipid: fat and phospholipids. The phospholipids have hydrophilic heads and hydrophobic tails which means that the heads are attracted to water and the tails are not. These phospholipids on the cell membrane equip it with the ability to keep certain materials out of the cell. That is why the cell membrane is called selectively permeable or semi-permeable.
The atmosphere is like the cell membrane.
The Atmosphere:

The Earth's atmosphere is what keeps the Earth's surface from being completely obliterated. It is made up of many layers, which makes it hard for foreign materials such as asteroids to pass through it and crash into the Earth's surface. It also keeps out the sun's rays and harmful radiation.
How are both of these alike?
The atmosphere and the cell membrane both have multiple layers and both keep out foreign substances. The cell membrane separates the cell's contents and its environment in the same way that Earth's surface is kept separate from space.
Volcanoes are like the ribosomes in a cell.
Ribosomes:

Ribosomes are organelles that make proteins. They are made in the nucleolus and can be either attached to the nucleus or free floating. Proteins are organic compounds that help build and repair the cell.
Volcanoes are like ribosomes in a cell.
Volcanoes:

Volcanoes are mountains that have holes or cracks in them. Lava and gas escape from the Earth's interior. This lava runs over the land and when it cools, new crust is formed.
How are both of these alike?
Ribosomes and volcanoes both release substances that build. Proteins build and repair cells and magma forms new crust.
The agents of deposition are like golgi bodies.
Golgi Bodies:

Golgi bodies are the packaging centers of the cell. The golgi bodies package and transport lipids and proteins that they receive from the smooth endoplasmic reticulum.
The agents of deposition are like golgi bodies.
Agents of Deposition:
Some agents of deposition include wind and water. Deposition is when sediment is moved from one place and laid down at another. Often, when these materials are picked up, they mix with other substances and when they are laid down and transported, they don't always end up the same as they start.
How are both of these alike?

Agents of deposition sometimes cause materials to mix together just like the golgi bodies package proteins and lipids. The agents of deposition also move the sediment in the same way that the golgi bodies transport or distribute the proteins and lipids.
Lakes and ponds are like vacuoles in an animal cell.
Vacuoles:

In animal cells, vacuoles are places for temporary storage of waste, water, and other materials. Therefore, since they are only for temporary storage, they are very small in animal cells. In plant cells however, since plants can't move, the vacuoles store their water and are bigger than the plant cell's nucleus.
Lakes and ponds are like vacuoles in an animal cell.
Lakes and Ponds:

Lakes and ponds get their water from runoff and precipitation. Unlike the ocean, which always has water, lakes and ponds can dry up. The water isn't always there.
How are both of these alike?

Vacuoles and lakes both act as temporary storage.
The lakes do not have the same water forever and the animal cell vacuoles do not have the same waste and water forever; it moves on. The vacuoles in an animal cell are also small and the amount of lake water compared to the world is also very small.
The crust and mantle are like the endoplasmic reticulum.
Endoplasmic Reticulum:

The endoplasmic reticulum an intercellular highway system that is attached to the nuclear membrane. ER transports materials into and out of the nucleus. ER can either be rough or smooth. Rough ER is ER that is covered in ribosomes and smooth ER transports others materials out of the nucleus.
The outer core is like the nuclear membrane.
Outer Core:

The outer core covers the inner core in which the iron alloys that generate the Earth's magnetic field are located. The magnetic currents have to pass from the inner core and through the outer core. The outer core consists of mostly iron and nickel.
The outer core is like the nuclear membrane.
Nuclear Membrane:

The nuclear membrane consists of pores that allow information and other things to pass through it and out or into the nucleus.
How are these both alike?
The nuclear membrane is there to let certain things out of the nucleus just like the outer core lets magnetic currents pass through it.
The iron alloys in Earth's core are like chromosomes.
Chromosomes:

Chromosomes are coiled DNA that are inside the nucleus. DNA contains the genetic information and controls the structure of a cell.
The iron alloys in Earth's core are like chromosomes.
Iron alloys:

The movement of the iron alloys in the inner core of the Earth is the cause of the magnetic field around Earth. The magnetic field protects the Earth's surface from harmful radiation from the sun. Without it, the Earth's surface would have already been demolished.
How are both of these alike?
The iron alloys control the balance of the Earth, just like the chromosomes control the structure of the cell. Without the chromosomes and the iron alloys, the Earth and the cell would not be what they are today.
The oceans and the land are like the cytoplasm.
Cytoplasm:

The cytoplasm is the gelatin-like substance inside the cell and everything inside of it, excluding the nucleus. The cytoplasm's main function in the cell is to keep things moving by constantly flowing.
The ocean and land is like the cytoplasm.
The Ocean and Land:

The ocean covers seventy percent of the Earth and the land is the other thirty percent. The ocean is always flowing and the land is always changing.
How are both of these alike?
The cytoplasm and the ocean are both liquids that are always flowing. The land and the organelles of a cell are their contents, which make them part of the cell.
Power plants are like mitochondria.
Mitochondria:
The mitochondria are the powerhouses of the cell. They produce energy in the form of ATP by breaking down sugars. The cell uses the ATP to do work.
Power plants are like mitochondria.
Power Plants:
Power plants take raw materials and turn them into a usable form of energy. There are many raw materials that are used to make energy: water, wind, waste, etc. These power plants give us energy in the form of electricity and we use that electricity to make things better.
How are both of these alike?
They both make energy into a usable form. Both make energy that helps the organelles or people make a better functioning cell or Earth.
The crust and mantle are like the endoplasmic reticulum.
Crust and Mantle:
The Earth's crust is what we live on and walk on. The crust can be rough or smooth terrain. Rough terrain is generally rough and hard to pass while smooth is easy to pass through and smoother.
Magma also passes through both of these layers.
How are both of these alike?
The endoplasmic reticulum transports materials to and from the nucleus just like magma is transported from the nucleus through the mantle and through the crust. Rough ER is like land with a lot of volcanoes.
