Ribosomes

• Ribosomes look like tiny dots attached to a network of membranes that runs throughout the cytoplasm. This network is called the rough endoplasmic reticulum.
• Ribosomes may just be scattered freely in the cytoplasm.
• Ribosomes are found in all types of cells - bacteria, protoctists, fungi, animals, and plants all have ribosomes in their cells.
• Ribosomes are the places where proteins are made, by joining amino acids together in a long chain.
