• The SUN is the source of energy for all life on the planet.

• Plants can turn sunlight into food, which animals can then eat.

But HOW do plants get their energy from the sun?

Photosynthesis (definition):

Photosynthesis is the chemical reaction that uses the energy from the sunlight to convert water and carbon dioxide into oxygen and high energy sugars (glucose).

Get out:

Oxygen

Glucose

Use:

Water

Carbon dioxide

Sunlight

In which organelles does this process take place?

• Light hits the chloroplasts in green leaves.

• That’s where photosynthesis happens.

• In chloroplasts, chlorophyll is the green pigment that absorbs sunlight.

Time for the four key things that plants need to do photosynthesis…

• From the sun!

(these are redwoods, the tallest trees in the world!)

• From the soil, up through a plant’s roots

• Or from rain

Water in

• From the air, through small holes in leaves called stomata

( The world’s oldest tree is 4800 years old! It’s in California.)

• New vocab!!!

• In chloroplasts, chlorophyll is the green pigment that absorbs sunlight and turns it into energy.

Chemical equation forPhotosynthesis:

Chemical equation: light + 6CO2 + 6H2O C6H12O6 + 6O2

light + carbon dioxide + water glucose + oxygen

Get out:

Oxygen

Glucose (food!!)

Use:

Sunlight

Water

Carbon dioxide

MEMORIZE THIS EQUATION!!!!

light + 6CO2 + 6H2O C6H12O6 + 6O2light + carbon dioxide + water glucose + oxygen

Trick for remembering photosynthesis:

Plants...Every child will get one.

Photosynthesis:energy + carbon dioxide + water glucose + oxygen

In your notebooks, for participation credit…

• Draw your own tree that is doing photosynthesis

• Label what the tree is using and what the tree is producing

• Be creative!

Plants can make their own food from sunlight (they don’t need to eat).

Organisms that can produce (create) their own food are called:

In Greek, auto = self and trophe = nutrition

Autotrophs are also sometimes called

producers.

What are some examples of autotrophs?

Organisms that need to eat for nutrition are called:

In Greek, hetero = another and trophe = nutrition

Heterotrophs are also sometimes called consumers because they consume the food

that producers create.

What are some examples of heterotrophs?

How living things get energy

(Know this information!)

Energy source

Name Example

Not from food/eating

Pine trees from the sun

From food/ eating

Deer eat grass, lions eat zebra

Aim: How can we prepare for our quiz on cells & diffusion?

• DO NOW: Write 6 key words that you will look for on Wednesdays’ quiz. Think about:– Cells (organelles)– Diffusion/Osmosis– Diffusion through a Membrane Lab

Lets things in and out

Site of protein synthesis

Where energy is released

Stores food, water, waste

Site of photosynthesis

Support and structure

Hey Brian…What 3 molecules are used in this lab?

1. Glucose2. Starch3. Iodine

Hey Quagmire…Why did the “cell” turn blue-black inside and not outside?

Since the I_______is small it could move I_________ the cell. Because S________ is too B______, it cannot move across the M_________. Since iodine is an I________ for starch, the I________ of the cell turned B_________.

Giggity!!!

Hey Cleveland…How do you know if the glucose moved out of the “cell”?

I know that G________ is a S______ molecule, so it will M_______ across the M_________. Since I cannot see it I would used an I_________. I used B_________ to test for the presence of glucose. Benedicts is B______ in color but when H_______ and glucose is present it turns

O_________.

Hey Stewie…What does the “Diffusion Through a Membrane” lab tell us?

This lab tells us that a cell’s m_________ is s________ permeable. That means that not everything can go through it. S______ molecules like g______ and I______ have no problems passing through. But molecules like s_______ and p_________ are too b____ to pass through.

Hey Chris…What did we learn in part two of the lab?

This lab tells us that salt C_______ move through the M__________. Instead W_______ move through by the process of O________. This is a special type of D_________ that involves the movement of water from one C_______________ to another.

Hey Peter…How did the onion cell look when it was in salt water?

CLICKNucleus

Cell Wall

Cytoplasm

Cell Membrane

Water leaves the cell. The cytoplasm shrinks but the cell wall remain the same shape.
