Across
- 1. is an organelle that specializes in photosynthesis in plants and many protists. Plant chloroplasts have two outer membranes, filled with a semifluid matrix called Stroma.
- 3. is the electromagnetic energy of light organized in packets.
- 5. pigments absorb additional colors of light for photosynthesis.
- 6. Organisms can harness the energy of light to build organic molecules from inorganic raw materials, all of these by this metabolic pathway.
- 8. is an organic molecule that selectively absorbs light of specific wavelengths.
Down
- 1. is by far the most common photosynthetic pigment in plants, photosynthetic protists, and cyanobacteria. It absorbs violet and red light, so it appears green.
- 2. process by which any molecule becomes broken down by light energy
- 4. The distance between the crest of two successive waves of light. It is measured in nanometers (nm)
- 7. membrane an inner much-folded membrane, that the Stroma contains.
- 9. semifluid matrix, found in the outer membranes of the chloroplast.
