Animal Cell Structure And Organelles

Animal Cell Structure And Organelles

1. Nucleolus

   • Where ribosomes are made
     • Ribosomes are made of RNA and several proteins
     • They are a necessary part in protein synthesis

2. Nuclear Envelope

   • A double membrane layer that surrounds the nucleolus
   • Dotted with thousands of nuclear pores
     • Allow materials to move in and out of the nucleus

3. Chromatin

   • Compacted string of DNA
   • Found in the nucleus
   • Chromosomes are formed from chromatin

4. Rough Endoplasmic Reticulum

   • Performs the synthesis of proteins
   • Transports many biochemical products
   • Dotted with ribosomes - hence the 'rough' ER

5. Smooth Endoplasmic Reticulum

   • Synthesises carbohydrates and lipids

6. Golgi Apparatus

   • To carry out the processing of proteins from the rough ER
   • Helps with the transportation of lipids around the cell and with the creation of lysosomes

7. Mitochondria

   • Performs respiration to produce energy in the form of ATP (adenosine triphospahte)

8. Ribosomes

   • Synthesise proteins out of mRNA
