  1. How Plants Produce food By: Tiffany Zhang & Ashley Tsai

  2. Summary of Lesson

  3. Vocabulary • Photosynthesis- The process by which plants transform energy from sunlight into chemical energy. • Grana- Stacks of membranes inside a chloroplast that contain chlorophyll • Chlorophyll- The pigment in the chloroplast that absorbs light. • Chloroplast- An organelle in plant cells in which photosynthesis takes place. • Stomata-Small openings in the bottom of a leaf through which gases move.

  4. Introduction • Everybody uses energy to conduct all life processes • The original source of energy is the sun. • Plants transform energy of sunlight into chemical energy, then stored in food. Plants along with bacteria and algae accomplish this process called photosynthesis.

  6. Photosynthesis • Photosynthesis is the process so that plants may convert energy and heat from the sun into chemical energy. While this process happens oxygen is released.

  7. This is a diagram of the process of Photosynthesis

  8. Plant Cells • The main reason why plants are able to produce food is that in plant cells there is an organelle called chloroplast. • Chloroplast is only found in plant cells. Chloroplasts contain pigments that absorb sunlight. The energy is used to make food- an unique process among organelles. Pigment organelles gives plants their green color.

  9. Here’s is a diagram of a Plant Cell
