PART 3: LEAF STRUCTURE 1. In what plant structures does photosynthesis occur? Make your description as specific as you can. 2. On Diagram 3, complete the following tasks. a. Draw how CO 2 gets into the leaf. b. Draw how O 2 gets out of the leaf. c. Label the name of the structure through which these gases pass.
Student Worksheet PART 8: TEST YOUR KNOWLEDGE 1. Based on everything you’ve learned from the animations, what is the overall purpose of photosynthesis? 2. Describe how oxygen gas (O 2) is produced during photosynthesis. Include the specific structures in the plant where the reaction occurs. 3.
Photosynthesis is the process by which the energy in sunlight is converted into chemical energy. Photosynthesis in plants takes place in the chloroplasts. The green color of a leaf comes from chlorophyll, a pigment found inside chloroplasts. A double membrane surrounds the chloroplast.
20 . 1.1 Photosynthesis. State the name of the green substance contained in plant cells that helps them to carry out this process. Explain why this green substance is needed. Zara used the apparatus to investigate the efect of changing the light intensity on the rate at which bubbles were produced. Describe how she can vary the light intensity.
Embedded in the thylakoid membrane are molecules of chlorophyll, a pigment (a molecule that absorbs light) through which the entire process of photosynthesis begins. Chlorophyll is responsible for the green color of plants. The thylakoid membrane encloses an internal space called the thylakoid lumen or space.
1. Plants gather the sun’s energy with light-absorbing MOLECULES called _____. A. thylakoids B. pigments C. chloroplasts D. glucose 2. Chlorophyll absorbs light very well in the _____ regions of the visible spectrum. (Circle all that are true) A. blue-violet B. green C. red D. yellow 3.
Photosynthesis is a process in which sunlight energy is used to make glucose. The site of photosynthesis is in the chloroplast – an organelle found in the leaves of green plants. The main functions of chloroplasts are to produce food (glucose) during photosynthesis, and to store food energy. Chloroplasts contain the pigment, chlorophyll ...
