Organelles of the animal cell and their functions

Organelles of the animal cell1. INTRODUCTION

The animal cell has 13 different types of organelles¹ with specialized functions.

Below you can find a list will all of them (animal cell organelles and their functions) with and image/diagram to help you visualize where they are and how they look within the cell.



  • Nucleolus: Synthesis of ribosomal RNA.
  • Nucleus: Contains genes (chromatin).
  • Ribosomes: Protein synthesis.
  • Vesicle: Transport of materials within the cytoplasm.
  • Rough endoplasmic reticulum (RER): Protein synthesis.
  • Golgi Apparatus: Processes, packages and distributes proteins to other organelles for export.
  • Cytoskeleton: Structural support of cells; facilitates the movement of the organelles.
  • Smooth endoplasmic reticulum (SER): Lipid synthesis; drug metabolism.
  • Mitochondria: Produces energy for the cell called ATP.
  • Vacuole: Protection of the cell, collect waste products and maintain internal pH, among others. (*) Only in some animal cells.
  • Lysosome: Cellular digestion.
  • Centrosome: regulate the cell-cycle progression.
  • Cell membrane: separates the cell from its environment; regulates the movement of materials in and out of the cell.

PhD in Education. I've been sharing all kind of content/information on the Internet for 14+ years now. I try to do it in the most straightforward and reliable way possible, cross-referencing information with the primary sources of authority in each field (unless unnecessary). You can reach out to me in the comments. I read all your inquiries and typically respond to most of them daily. If you find what I do helpful, you can support me here. 🙂




  1. Thank you this will really help me for my assessment in 2 days.

  2. very helpful in 2 days my project is due and this helped a lot I’m almost done it now and I just started.

  3. This website is really helpful because it is really easy to understand also because I have a project due on Monday.

  4. Oh my gosh thank you for this because I have a project due tomorrow that i didn’t even know about and its about organelles and this is the only website that helped so far!!

  5. i did this in class i was speaking in class then a water flow of shit rolled out of my body it was like a damn in my ass had broke
