BELL WORK:Copy the bolded part of the question and write

your answer.Like complex carbohydrates, proteins are biomolecules that serve many functions and can be chemically broken down and restructured. Both proteins and complex carbohydrates are which of the following? A Polymers of smaller subunitsB Sequences of sugarsC Lipids of large moleculesD Nucleotides of DNA

CO: I will compare the products and reactants of photosynthesis

and cellular respiration.

LO: I will write notes. I will discuss photosynthesis & cellular respiration with a partner.

Anticipation Thoughts…

1. Thigmotropism is a plant’s response to gravity.2. Transpiration is how plants absorb water

through their roots.3. The stomata allows water into the leaves.4. The guard cells open and close the stomata at

the most opportune times of day for the plant.5. Plants produce glucose during photosynthesis.

Cellular Energy

• Energy :the ability to do work

• Most energy comes from the sun in the form of light.

• All energy leaves the

Earth in the form of heat.

• Adenosine triphosphate (ATP) is the chemical that cells use to store and release energy.

• The energy in ATP is stored in the bonds between the elements.

What biomolecule does ATP look like?

II. Photosynthesis

• To perform photosynthesis, plants need:1. sunlight (energy source)2. water3. carbon dioxide

These are called the reactants.

• After photosynthesis, the plant has produced:1. Glucose (molecule that the plant uses to

produce energy)2. Oxygen (given off through the leaves)

These are called the products.

SUNLIGHT

The equation of photosynthesis is:

6CO2 + 6H2O + sunlight C6H1206 + 6O2

carbon dioxide + water + energy glucose + oxygen

Talk to your partner:Where do plants get carbon dioxide?

How do plants take in water?

Photosynthesis occurs in an organelle in the leaves.

Chloroplasts: organelle where photosynthesis takes place

Chlorophyll: pigment in chloroplasts, makes plants green

III. Cellular Respiration

• Cellular respiration: the process that releases energy by breaking down glucose.

• Cellular respiration occurs in the mitochondria of plant and animal cells.

• Cellular respiration makes 36 ATP molecules

• The remaining energy is lost as heat.

Mitochondria

The formula for cellular respiration is:

6O2 + C6H12O6 6CO2 + 6H2O + Energy

oxygen + glucose carbon dioxide + water + ATP

Cellular respiration requires oxygen and glucose and gives off carbon dioxide,

water, and energy.

Talk to your partner:

If humans do not make our own food in photosynthesis, how do

we get glucose for cellular respiration?

SAGE & SCRIBE1. You will be working with the person next to you.2. First round:– Partner A/C: Describe photosynthesis in WORDS– Partner B/D: Write the EQUATION for

photosynthesis

3. Second round:– Partner B/D: Say the cellular respiration EQUATION– Partner A/C: Write the WORDS for cellular

respiration

At the bottom of your page, choose ONE equation and draw

pictures to represent each of the products and reactants.
