PALEOZOIC PERIOD
The Cambrian Period is the age of trilobites. Also the Cambrian Period is named after a place in Great Britain named Cambrea. The Cambrian Period was all in water. I do not know how long the Cambrian Period lasted.
Soon it was the Ordovician Period! The Ordovician Period was the age of sea lilies. The sea lilies were most abundant. Sea lilies waved their arms to get their prey. There were many animals in the Ordivician period. Ordivician Period was named after the Odovice tribe.
Next it was the Silurian Period! The Silurian Period again was an age of sea lilies. There were more animals in the Silurian Period than the Ordovician Period.
Next it was Devonian Period!!!!!! The Devonian Period was the age of fishes. Even the shark came in the Devonian Period.
Next it was the Carboniferous Period. The Carboniferous Period was the age of Plants. Lots of Plants came in the Carboniferous Period. The Carboniferous period was named after all the Carbon that got trapped in the Earth.
After the Carboniferous Period it was the Permian Period. In the Permian Period there were huge reptiles.They were 10 times as big as us humans. (Silurian Period was the second smallest Period and Permian Period is the smallest Period)
WELCOME TO THE CAMBRIAN PERIOD
The Cambrian Period is the first Period in the timeLine of life. Cambrian Period is named after a place in Great Britain named Cambia where the first fossils where found. A lot of Trilobites came in Cambrian Period. Trilobites dominated the seas. Simple animals came during the Cambrian Period like Sponges. These simple animals like Sponges have no brain, heart or eyes! Cambrian Period is known as the age of Trilobites. After the Cambrian Period and before the Ordovician Period there was an Ice Age. There was no predators to eat the Trilobites so the Trilobites dominated the seas........to be continued.
WELCOME TO THE ORDOVICIAN PERIOD
The Ordovician Period is the Second Period in the timeline of life. The Ordovician Period is named after a tribe called the Odovice tribe. A lot of Sea Lilies came in the Orovikin Period. Sea Lilies dominated the Seas of the Ordovician Period, Silurian Period and Devonian Period. Now there were predators that came to eat the Trilobites and the population of Sea Lilies grew. Even though the Sea Lilies were dead by the time of Devonian Period they already had dominated the seas.
Many animals came in the Ordovician Period........to be continued.
WELCOME TO THE SILURIAN PERIOD
The Silurian Period is named after a tribe called the Sulores tribe. Silurian Period is the age of Sea Lilies again. The Silurian Period Is the 3 period on the timeline of life. Again Sea Lilies dominated the seas. But the Sea Lilies grew even abundanter in Silurian Period then the Ordovician Period. Almost all the Trilobites died in the Silurian Period.
CELLS
BACTERIUM: Have no nucleus.Have a cell wall. Have 3 regular shapes. Few have chloroplasts. Have no large vakuol.
PLANT: Have a nucleus. Have a cell wall.Have a regular shape.Have chloroplasts. Have a large vakuol.
ANIMAL: Have a nucleus. Have no cell wall. Have no regular shape. Have no chloroplasts. Have no large vakuol.
PARTS OF A CELL
CELL: A cell is the smallest unit of life. It is a highly organized system that feeds, excretes, builds and maintains its own structure and reproduces itself. There are many kinds of cells. Some live by themselves and others are part of a large organism in which they may each play only a small role.
NUCLEUS: The nucleus is the part of the cell that contains the chromosomes. It is surrounded by a nuclear membrane which is only two molecules thick that controls the movements of gasses, nutrients and waste into and out of the cell.
MITOCHONDRIA: Mitochondria use carbohydrates to make energy for the cell.
CYTOPLASM: The cytoplasm is the part of the cell between the nucleus and the cell membrane. In it all of the processes that maintain the cell's life in that place. It is a thick soup of simple and complex chemicals and membrane structure called organelles (little organs).
VACUOLES: Vacuoles are bubbles the cells make to store things or move them through the cytoplasm. They are made of cell membrane.
TREE OF LIFE
The tree of life has 6 branches.The branches show the enormous variety of life. Bacteria is the smallest life form. You cannot see bacteria with the naked eye. Monara,Protesta,Fungi,Plant,and Animal are the five kingdoms.
BACTERIA: Archaea was discovered in 1970 and it was added to the tree of life. It was found in a hot spring in Yellowstone National Park. Archaea can live in boiling hot temperatures.
MONERA: Monera is the oldest and first living species on the tree of life. They are 5.3 billion years old. Monera is the reason there is life on Earth.
