Cell Parts (cont. ) 2. Cytoplasm: “Living stuff” n Jello-like substance that gives the cell shape and suspends the organelles (little organs). n All the chemical reactions take place here! It’s a boppin’ busy place!

Cell Parts (cont. ) 3. Nucleus: “Control Center” n n n Usually near the

Cell Parts (cont. ) 3. Nucleus: “Control Center” n n n Usually near the middle (center) of the cell surrounded by a nuclear membrane Contains the genetic information “DNA” Nucleolus: Place where ribosomes are made.

Cell Parts (cont. ) 4. Ribosomes: “protein factories” n n Proteins are made here!!

Cell Parts (cont. ) 4. Ribosomes: “protein factories” n n Proteins are made here!! Think spots or dots!

Cell Parts (cont. ) 7. Mitochondria- “Powerhouse” n Respiration center--sugar is burned to create Energy!

Cell Parts (cont. ) 8. Lysosome - “Garbage disposal, suicide sac” n n n

Cell Parts (cont. ) 8. Lysosome - “Garbage disposal, suicide sac” n n n Contain digestive enzymes to break up worn out cell parts and invaders like bacteria Sometimes digest really bad stuff and die so the cell can live. Look like waffles

Peroxisome Membrane sacs containing enzymes to detoxify harmful substances and disarm free radicals. n

Peroxisome Membrane sacs containing enzymes to detoxify harmful substances and disarm free radicals. n Converts free radicals to hydrogen peroxide then catalase converts that to H 2 O and O 2. n
