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.

Plasma Membrane

Exterior of SchoolPlasma Membrane

Plasma Membrane

Like the exterior of a school, the plasma membrane controls what enters and leaves a cell.

Nucleus

Like a principal, the nucleus controls what the cell does and what it produces.

Nucleus Principal

Mitochondria

Like a lunch room, the mitochondria provide energy for the cell to function.

Mitochondria Lunch Room

Endoplasmic Reticulum

Like a copy room, the ER is the place where the product (proteins) of the cell are made

ER Copy Room

Like printers, the ribosomes make the products (proteins) of the cell

Ribosomes Printers

Golgi Apparatus

Like the mail room, the golgi apparatus packages materials for transport out of the cell

Golgi Apparatus Mail Room

Lysosome

Like garbage disposal, the lysosomes get rid of waste materials in the cell

Lysosomes Garbage Disposal

Cytoskeleton

Like school walls, the cytoskeleton helps maintain shape and anchor organelles in place

Cytoskeleton Walls

Animal Cell

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

CentrioleBundle of tubes, which line up the DNA and separates it during animal cell division

Plant Cell

ChloroplastStores energy for later; contain green pigment; captures light energy (sunlight) and converts it to chemical energy (glucose)

Central VacuoleStores water, maintains fluid balance, keep pressure on cell wall to keep it rigid

Cell WallSurrounds plants cells; provides structural support and protection

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 .

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.

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.
