1 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 subunits B Sequences of sugars C Lipids of large molecules D Nucleotides of DNA

2 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.

3 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.

4 Cellular Energy

5 Energy :the ability to do work

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

7 All energy leaves the Earth in the form of heat.

8 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?

9 II. Photosynthesis

10 To perform photosynthesis, plants need: 1. sunlight (energy source) 2. water 3. carbon dioxide These are called the reactants.

11 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.

12 SUNLIGHT The equation of photosynthesis is: 6CO 2 + 6H 2 O + sunlight  C 6 H 12 0 6 + 6O 2 carbon dioxide + water + energy  glucose + oxygen

13 Talk to your partner: Where do plants get carbon dioxide? How do plants take in water?

14 Photosynthesis occurs in an organelle in the leaves. Chloroplasts: organelle where photosynthesis takes place Chlorophyll: pigment in chloroplasts, makes plants green

15 III. Cellular Respiration

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

17 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

18 The formula for cellular respiration is: 6O 2 + C 6 H 12 O 6  6CO 2 + 6H 2 O + Energy oxygen + glucose  carbon dioxide + water + ATP Cellular respiration requires oxygen and glucose and gives off carbon dioxide, water, and energy.

19 Talk to your partner: If humans do not make our own food in photosynthesis, how do we get glucose for cellular respiration?

21 SAGE & SCRIBE 1.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

22 At the bottom of your page, choose ONE equation and draw pictures to represent each of the products and reactants.

23 The rest of class: Complete the Photo vs CR Foldable
