Name that City!

What does this have to do with science???

What is an organelle? Organelles are structures inside of a cell that perform specific jobs for that cell.

Quick Review! Cell Membrane- a protective layer that covers the cell’s surface and acts as a barrier.

Quick Review! Nucleus- a membrane-bound organelle that contains the cell’s DNA and makes sure that roles like growth, metabolism, and reproduction occur.

Now onto the new stuff!

Mitochondrion Mitochondrion-the organelle which breaks down sugar to produce energy for the cell. The “power house” of the cell.

Golgi Complex Golgi Complex- the organelle that packages and distributes proteins

Endoplasmic Reticulum ER- an organelle in which proteins, lipids and other materials are made, processed, and transported through the cell.

Ribosomes Ribosomes-organelles that are responsible for making proteins for the cell. The cell needs protein to live.

Lysosomes Lysosomes- organelles that have digestive enzymes, get rid of waste.

Vacuole Vacuole-the organelle that stores water and other materials

Chloroplasts Chloroplasts- organelles that use sunlight to make food for the cell.

Cytoskeleton Cytoskeleton- keeps the cell membrane strong, is responsible for cell movement.

Cell Wall Cell Wall- a rigid structure that surrounds the membrane and gives the cell support.

Does this sound familiar?

How is a Cell like a City? ________________________________________ 1) Now, you are going to make your very own cell city! 2) You must draw a picture of a city that shows how a cell works. You must include at least 7 organelles, but you are allowed to use all 11. It can be a plant or animal cell. Just make sure you remember which organelles go in which cell! 3) On the back of your city, you will write an explanation of what is representing that organelle and why you chose that. For example: “I chose to use a power plant as the mitochondria because a power plant gives energy to the city just like the mitochondria give energy to the cell.
