The Cell-Ribosomes

What is a ribosome?

When you look at pictures of cells, you can see tiny dots on the ER and in the cytoplasm.

These dots are ribosomes, but why are they important to the cell?
Ribosomes are small protein factories found in cells.
They are located in the cytoplasm and on the rough ER.
Ribosomes look like small dots on the ER and in the cytoplasm.
Ribosomes are found in plant,animal, and bacterial cells.

How does a ribosome make a protein?
mRNA that has been created at the nucleus and travels to the ribosome.
tRNA travels to the mRNA and reads it in triplets called codons.
The tRNA has an amino acid on one end.
The tRNA reads the mRNA and strings the amino acids together in the correct order.

Why is protein important?
Protein is used for many functions in the cell.
Proteins are used as building blocks and structure suppor. Your skin, and tendons are made up of protein.
Some proteins help with digestion.
Proteins help with muscle contraction, and carry oxygen around the body.
These tiny organelles play a very important in helping organisms stay alive.
