Do you know what organelles Do you know what organelles are? Well, we have are? Well, we have organsorgans… …

cells have cells have organellesorganelles. We . We have a have a heart, lungsheart, lungs, and , and

kidneyskidneys; they have a ; they have a nucleus, nucleus, mitochondriamitochondria.. blah blah blah!.. blah blah blah!Got it?

Good!

Do you know all of the names and Do you know all of the names and functions of all of the organelles?functions of all of the organelles?

Yeah.. me neither. =)

The good news is … you don’t have to know them all! Woo Hoo

You DO have to know a few important ones. Let’s see…

FIRST…LET’S LOOK AT THE CELL….FIRST…LET’S LOOK AT THE CELL….Now, let’s remove the confusing stuff first.

Yesssssss….. Much Better =)

The ones you have to know are…The ones you have to know are…1) 1) NucleusNucleus 2) 2) Cell membraneCell membrane3) 3) MitochondriaMitochondria 4) 4) ChloroplastChloroplast

5) 5) Cell wallCell wall

Sound familiar? At least a little bit? On the next slide,find them on the picture!!

1) 1) NucleusNucleus 2) 2) Cell membraneCell membrane3) 3) MitochondriaMitochondria 4) 4) ChloroplastChloroplast

5) 5) Cell wallCell wall

Where are the chloroplasts and cell Where are the chloroplasts and cell wall????wall????

YUP… you’re right. You only find those in plant cells. THIS is an animal cell.

THIS is a plant cellTHIS is a plant cellThis is a chloroplast

The cell wall is the THICK layer outside of the cell membrane.

Usually, a plant cell is RECTANGULAR…

LIKE THIS

So there ARE some differencesSo there ARE some differencesbetween plant and animal cells. between plant and animal cells.

Why type of cells have cell walls? Plant Cells

What type of cells are sometimes drawn to look rectangular?

Plant Cells

More differences…. More differences….

Why type of cells have a nucleus? THEY BOTH DO!! This is where both plants and animals carry their DNA!!!!

This is why PLANTS (NOT ANIMALS) can make their own food!!!!!!

What type of cells have chloroplasts?Plant Cells

Let’s focus in on the …Let’s focus in on the …

They’re green!

This is why plants are green!

You See??

ChloroplastsChloroplasts

This is where plants MAKE their own This is where plants MAKE their own food. They can make enchiladas, food. They can make enchiladas, tacos, and sometimes quesadillas tacos, and sometimes quesadillas whenever they want. whenever they want.

Ha whatever. All that they can make is glucose sugar through a process called…?Umm… this is where you tell me the

answer. At least guess!

Photosynthesis!!!!!!!Photosynthesis!!!!!!!

CarbonDioxide

Water

Oxygen

Sugar

Energy

Teacher! Would you give the kids at least one full minute to look over the picture! Gosh…Some teachers are so unbelievable… ha =)

Okay… so what goes in and out of Okay… so what goes in and out of plants in photosynthesis??plants in photosynthesis??

WHAT? YOU FORGOT?LOOK AT IT AGAIN!!!

Photosynthesis!!!!!!!Photosynthesis!!!!!!!

CarbonDioxide

Water

Oxygen

Sugar

Energy

You’ll remember it now right??

Okay…so what goes in and out of Okay…so what goes in and out of plants in photosynthesis??plants in photosynthesis??

CO2 + H20 + ENERGY C6H12O6 + O2

Ready for the answer?? You need another look?

Too bad. =)

So what about…So what about…

NOT GREEN

Mmmm… if photosynthesis Mmmm… if photosynthesis occurs in chloroplasts, what occurs in chloroplasts, what

process occurs in mitochondria?process occurs in mitochondria?

Once again, I’m waiting

for some kind of answer.

Ready for the answer?

Cellular RespirationCellular Respiration

CarbonDioxide

Oxygen

Sugar

Energy

We use the food that we eat (sugar) to give us energy! Without this energy, we would die =) (If you don’t eat, you starve to death… duh).

For some reason, this looks familiar…

Ummm….Ummm….

Yeah! It’s the exact opposite of photosynthesis!

So you think you can remember what goes in and out? Study for a second… =)

So what goes in and out of So what goes in and out of mitochondria during cellular mitochondria during cellular

respiration? respiration?

Yeah yeah… just one more look..

Okay!! Tell me what I Okay!! Tell me what I want to hear!!!want to hear!!!

What comes in and What comes in and out of mitochondria out of mitochondria

during cellular during cellular respiration?respiration?

Okay ready??Okay ready??Since photosynthesis in the chloroplasts looks like this…

CO2 + H20 + ENERGY C6H12O6 + O2

Cellular respiration in the mitochondria looks like …

GUESS!!

C6H12O6 + O2 CO2 + H20 + ENERGY

TOO EASY!!!!!!!

Key Points to Discuss for a Second Key Points to Discuss for a Second

In Class Before The Small QuizIn Class Before The Small Quiz-How are plant and animal cells different?

-What does the nucleus have inside of it?

-What process occurs in mitochondria? How about in chloroplasts?

-What do plant cells have that they use to make their own food?
