3 Photosynthesis Process in which LIGHT energy is converted into CHEMICAL energy (food) Autotrophic nutrition

4 Occurs in chloroplasts

5 –Contain chlorophyll = green pigment that absorbs light A B C F E D

6

7 Equation Carbon + dioxide wateroxygen glucose + water + light Chlorophyll light 6CO 2 +12H 2 O C 6 H 12 O 6 +6H 2 O +6O 2 Chlorophyll (food) (wastes)

10 Light nth/action.htmlhttp://www.phschool.com/science/biology_place/biocoach/photosy nth/action.html Most effective: blue & red –Easily absorbed

11 Least effective = green –reflected

12 What is the glucose used for? Respiration (aerobic) Glucose ATP

16 Why are plants important to living things?

17 1. Produces food for itself & all other organisms (food chains)

18 2. Removes CO 2 from the air & adds O 2

20 Let’s review… 1.What are the raw materials of photosynthesis. 2.In which cell organelle does photosynthesis occur? 3.For which life process is the glucose produced used for? 4.Give one difference between photosynthesis and cell respiration.

21 Review: Identify whether the substance is a raw material, product or source of energy. 1.Oxygen 2.Carbon dioxide 3.Sunlight 4.Water 5.Glucose

22 Green plants make food by the process of a. photosynthesis b. respiration c. excretion d. digestion

23 The gas released during photosynthesis is a. oxygen b. carbon dioxide c. nitrogen d. carbon monoxide

24 The basic food material produced by green plants is a. fat b. glucose c. proteins d. minerals

25 The substance is green plants that captures the sun’s light energy is a. chlorophyll b. mesophyll c. phloem d. cuticle

26 During photosynthesis, molecules of carbon dioxide and water are changed into a. oxygen and carbon dioxide b. glucose and water c. glucose and chlorophyll d. oxygen and glucose

27 Which of the following materials is not needed for photosynthesis? a. sunlight b. chlorophyll c. water d. oxygen

28 A process in which glucose is broken down to release energy is called a. diffusion b. respiration c. photosynthesis d. osmosis

29 Aerobic respiration requires a. oxygen b. carbon dioxide c. light d. chlorophyll

30 One substance that is generated from aerobic respiration is a. ATP b. protein c. glucose d. oxygen

31 Respiration occurs in a. chloroplasts b. nuclei c. mitochondria d. ribosomes
