Bill Nye “Flowers”

The function of the flower in a plant is to allow _________________________.

The function of the flower in a plant is to allow REPRODUCTION.

Complete as we go…

The process of the male part of a plant fertilizing the female part of a plant, through pollen, is called _____________________.

The process of the male part of a plant fertilizing the female part of a plant, through pollen, is called POLLINATION.

Complete as we go…

Complete as we go… Petals: Attract insects and bees to the flower for

pollination

Complete as we go… Sepals: Green, leaf-like structures around the

petals to protect the growing flower

Complete as we go… Stamen: the male reproductive structure, holds

the ANTHER

Complete as we go… Anther: Produces the pollen than contains the

sperm (to fertilize female part)

Complete as we go….Pistil: The female reproductive structure, in

center of flower

Complete as we go…Ovary: At the bottom of the pistil, contains the

ovules which hold the eggs

1. _________ attract, birds, bees, or other animals that can carry _________, called _____________.

2. ___________ from the ______________ rubs off on the _____________________.

3. The pollinator carries that ________________ to the _____________ of the same or a different flower (“______________________”)

4. The _______________ of that flower grows into the fruit or vegetable

Pollination Steps

1. PETALS attract, birds, bees, or other animals that can carry POLLEN, called POLLINATORS.

2. ___________ from the ______________ rubs off on the _____________________.

3. The pollinator carries that ________________ to the _____________ of the same or a different flower (“______________________”)

4. The _______________ of that flower grows into the fruit or vegetable

Pollination Steps

1. PETALS attract, birds, bees, or other animals that can carryPOLLEN, calledPOLLINATORS.

2. POLLEN from the ANTHER rubs off on the POLLINATOR.

3. The pollinator carries that ________________ to the _____________ of the same or a different flower (“______________________”)

4. The _______________ of that flower grows into the fruit or vegetable

Pollination Steps

1. PETALS attract, birds, bees, or other animals that can carryPOLLEN, calledPOLLINATORS.

2. POLLEN from theANTHER rubs off on thePOLLINATOR.

3. The pollinator carries that POLLEN to the PISTIL/OVARY of the same or a different flower (“FERTILIZATION”)

4. The _______________ of that flower grows into the fruit or vegetable

Pollination Steps

1. PETALS attract, birds, bees, or other animals that can carryPOLLEN, calledPOLLINATORS.

2. POLLEN from theANTHER rubs off on thePOLLINATOR.

3. The pollinator carries thatPOLLEN to thePISTIL/OVARY of the same or a different flower (“FERTILIZATION”)

4. The OVARY of that flower grows into the fruit or vegetable

Pollination Steps

Complete as we go….

•When fertilization occurs the ovary grows into the fruit or vegetable. • The length of night or dark

period controls flowering.

Write in Notebook..

• Plants need these 4 key ingredients:

Video on Photosynthesis

• Discovery Education: Oxygen and Green Plants: The Process of Photosynthesis

What does photosynthesis mean?

• Photo = light

• Synthesis = putting things together

• Photosynthesis = putting things together with

light

WRITE IN NOTEBOOK

• Reactants (what goes in)• What plants use!

Water + Carbon Dioxide

(H2O) (CO2)

+ ENERGY from sunlight

WRITE IN NOTEBOOK

• Products (what comes out)• What plants produce!

Oxygen + Sugar (O2)

(C6H12O6)

Photosynthesis

• Photosynthesis is how plants use sunlight to make oxygen and sugar.

Reactants (what goes in) Products (what comes out)

Oxygen + Sugar (O2) (C6H12O6)

Water + Carbon Dioxide(H2O) (CO2) + ENERGY from sunlight

BrainPOP!

But I like this one better….http://www.youtube.com/watch?v=4CK4z4MDXuE

WRITE IN NOTEBOOK…

• We need O₂ for 2 reasons…• Respiration: Using our lungs to breathe

in oxygen and breathe out carbon dioxide

• Cellular Respiration: A chemical reaction that uses oxygen to break down stored energy from glucose; happens in cells

So what happens when you breathe?

BUT IT’S NOT THIS SIMPLE….

Oxygen (O2) goes in

Carbon dioxide (CO2) goes out

Discovery Ed Video• Cellular Respiration: Releasing the Stored

Energy in Glucose• Think about these questions when watching: 1. What happens to glucose in the presence of

oxygen? 2. How are photosynthesis and cellular respiration

related?

Respiration – Write in Notebook• Respiration is the process that breaks

down sugar to make energy. It happens in animal cells and plant cells.

• Cellular Respiration Equation:

Reactants (what goes in)

Oxygen + Sugar (O2) (C6H12O6)

Products (what comes out)

Water + Carbon Dioxide(H2O) (CO2)

+ ENERGY!!

So where does all this oxygen come from??

• Remember, it is due to green plants doing PHOTOSYNTHESIS!

Which of the following statements are true?

1. Photosynthesis is like respiration in reverse

2. Photosynthesis produces CO23. Photosynthesis needs sunlight

Copy the TWO statements that are true in your notebook

1. Photosynthesis is like respiration in reverse

2. Photosynthesis produces CO23. Photosynthesis needs sunlight

Photosynthesis Cellular Respiration

Food accumulated (Gets bigger and bigger)

Food is broken down.

Energy from the sun and stored as glucose

Energy of glucose released.

Carbon dioxide taken in. Carbon Dioxide is given off.

Oxygen given off. Oxygen is taken in.

Produces glucose. Produces carbon dioxide and water.

Goes on only in sunlight Goes on in light and darkness

Occurs only if there is chlorophyll

Occurs in all living cells.

Respiration is the opposite of Photosynthesis!

What is Transpiration?

Transpiration Poster

Transpiration

• Outside of Leaves: epidermis, waxy cuticle and stomata = prevent water loss.

• Guard cells surround and control the size of the openings in the stomata (control transpiration)

• The loss of water through the stomata is called transpiration.
