Parts of a Eukaryotic Cell

Parts of a Eukaryotic Cell

1. Nucleus

   • Membrane-enclosed organelle, found in most eukaryotic cells, which stores the genetic material (DNA).
   • Largest organelle in the cell.

2. Plasma Membrane (Cell Membrane)

   • A thin layer of lipids that surrounds the cell, separating the cytoplasm and organelles inside the cell from the surrounding environment.
     • Regulates what goes in and out of the cell. (is semipermeable)
   • Found in all cells.

3. Cytoplasm

   • Made up of cytosol and ribosomes and is the material inside the plasma membrane.
   • Found in all cells.

4. Ribosomes

   • Where proteins are synthesized.
   • Found in all cells.

5. Mitochondria

   • Organelle where cellular respiration occurs.
   • Has its own DNA.

6. Endoplasmic Reticulum (ER)

   • Rough ER
     • An organelle that helps transport and make proteins and lipids.
     • It is rough because it has ribosomes embedded on its surface.
   • Smooth ER
     • An organelle that helps transport and make proteins and lipids.
     • It is smooth because it doesn't have ribosomes embedded on its surface.

7. Cytoskeleton

   • Helps cell keep its shape and holds all organelles in their place.

8. Golgi Apparatus

   • Organelle that processes proteins and prepares them for use both inside and outside cells.

9. Vesicle

   • Small Membrane-enclosed sack that can store or transport substances.

10. Vacuole

    • Large sack filled with water that contains organic and inorganic molecules.
