Reflect: (3 Minutes)
1. What is a “cell”? Where do you find “cells”?
2. What are two cells you encounter everyday?

Organelles – Parts of a Cell
• Many different organelles in eukaryotic cells.
• Each has different structure and function.

Analogies (Just like …)
There are lots of different parts of cells (organelles)
They Work Just Like the parts of big factories, office building or even schools.

Projectiles
short, numerous, surrounds the entire cell
long, few-1 to 3, found at the ends of cell
Allows animal cells to move in watery environments and capture food

Guided Reading Read each section of the article
“When Cells Face an Energy Crisis” about the disorders caused by mitochondria malfunctioning.
As you read, answer the corresponding questions to help you summarize some of the significant points in the article .
![Page 31: Reflect: (3 Minutes)](https://reader036.vdocuments.us/reader036/viewer/2022062501/568165e2550346895dd90193/html5/thumbnails/31.jpg)
Think It Out
Breakthroughs in medicine and technology arise from people thinking innovatively about concepts that have been about for a very long time, such as the research on rare mitochondrial disorders, you just read about.
![Page 32: Reflect: (3 Minutes)](https://reader036.vdocuments.us/reader036/viewer/2022062501/568165e2550346895dd90193/html5/thumbnails/32.jpg)
Think It UpSelect an organelle, NOT mitochondria, and
write out its function. Think about what would happen to the cells and the organism made up of these cells if this organelle malfunctioned.
Write 75-100 words to describe the malfunction (What is this organelle not doing or doing to much of? What should it be doing?). Predict how this will affect the cells and the organism (Will it die? Will it not be able to reproduce? How and why?).
Be creative and detailed in your description.
