nucleus
What is the role of the nucleus?
directs the synthesis of all proteins in the body
What are the three parts of cytoplasm?
- ) cytosol
- ) cytoskeleton
- ) organelles
What organelle is the site of protein synthesis?
ribosomes
What organelle contains enzymes that detoxify harmful chemicals?
peroxisomes
What is the “powerhouse of the cell?”
produces ATP
mitochondria
What organelle stores proteins made by ribosomes?
Rough Endoplasmic Reticulum
What organelle has lipid synthesis and detoxification reactions?
Smooth Endoplasmic Reticulum
What organelle packages proteins for export throughout the cell?
Golgi Apparatus
What organelle digests worn-out, old cell organelles (cleans up)?
Lysosomes
What organelle directs the formation of the mitotic spindle during mitosis and forms the bases of cilia and flagella?
Centrioles
What is the main function of ribosomes?
