4  Photosynthesis  Photosynthesis- A process by which plants convert sunlight, water, and carbon dioxide into chemical energy, glucose (sugar), and oxygen  Chloroplast  Chloroplast- A cell organelle containing chlorophyll where photosynthesis takes place.  Chlorophyll  Chlorophyll- A green molecule which uses light energy from sunlight to change water and carbon dioxide gas into glucose and oxygen

5 Chlorophyll is the green pigment inside the chloroplasts of plant cells that makes leaves green!

6 CO 2

7 Sugar + O 2 O2O2O2O2

8 The Xylem A transport tissue with the basic function to transport water from the roots throughout the plant. 8 Xylem is found in the roots and stems of plants and is like a tiny tube. The “strings” in celery are xylem tubes.

10 How is a xylem in a plant similar to a circulatory system in a human? 10

11 A process where plants make their own food. 11

12 Photosynthesis occurs in the leaves of plants. 12 Can you name the structure in a leaf that is responsible for photosynthesis?

13 Radiant Energy Water Carbon Dioxide CO 2 13

14 Carbon + Water +sun  glucose + oxygen Dioxide (sugar) 6CO 2 + 6H 2 O +sun  C 6 H 12 O 6 + 6O 2 Glucose – chemical energy in the form of a sugar Photosynthesis Equation

15 Oxygen 15

16 Write to complete this sentence: During photosynthesis, _________ energy is converted into __________ energy. 16

17

18  Animals use:  Sugar (from producers/plants)  Oxygen (from producers/plants)  Plants use:  Carbon dioxide (from animals)
