Eukaryotic Cell Organelles and Function 1. Nucleus Nickname: “The Control Center” Function: holds the DNA Parts: 1. Nucleolus: dark spot in the middle of the nucleus that helps make ribosomes

Endoplasmic Reticulum 2 Types: 1. Rough ER: Rough appearance because it has ribosomes 2. Smooth ER: NO ribosomes Function: makes fats or lipids

Eukaryotic Cell Organelles and Function 5. Lysosomes: circular, but bigger than ribosomes:) Nickname: “Clean-up Crews” Function: to break down food into particles the rest of the cell can use and to destroy old cells

Eukaryotic Cell Organelles and Function 6. Mitochondria Nickname: “The Powerhouse” Function: Energy formation Breaks down food to make ATP ATP: is the major fuel for all cell activities that require energy

Peroxisomes Peroxisomes function to rid the body of toxic substances like hydrogen peroxide, or other metabolites

Microtubules Microtubules give the cell its shape and create pathways for the movement of organelles within the cell.

Microfilaments Thin filaments of protein actin which function in structure and movement in eukaryotic cells.

Now let’s talk about structures only found in Animal Cells!!

Centrioles Centrioles are small, cylindrical structures located just outside the nucleus. They play a role in chromosome separation during the cell division.

Cilia and Flagella Cilia are short hairlike projections. Flagella are long projections that move in whiplike motion. For single-celled eukaryotes, cilia and flagella are essential for the locomotion of individual organisms.

Now let’s talk about structures only found in PLANT Cells!!

Eukaryotic Cell Organelles and Function 7. Vacuoles Function: stores water This is what makes lettuce crisp When there is no water, the plant wilts

Eukaryotic Cell Organelles and Function 8. Chloroplasts Function: traps energy from the sun to produce food for the plant cell Green in color because of chlorophyll, which is a green pigment
