Across
  1. 7. an organism that gets its food by eating other living things, such as plants or animals, instead of making its own food
  2. 8. small openings on the surface of leaves that allow for gas exchange, enabling carbon dioxide to enter and oxygen to exit the plant.
  3. 11. The natural light that comes from the sun, providing the energy necessary for photosynthesis to occur in plants.
  4. 14. an organism that can produce its own food using inorganic substances, typically through processes like photosynthesis or chemosynthesis
  5. 15. A gas produced as a byproduct of photosynthesis, released into the atmosphere by plants and essential for the respiration of most living organisms.
  6. 16. The green pigment found in chloroplasts that absorbs light energy for photosynthesis, primarily in the blue and red wavelengths.
  7. 18. The process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose, using carbon dioxide and water.
  8. 21. A waxy, protective layer covering the surface of leaves and stems that reduces water loss and protects against pathogens.
  9. 22. Substances that are formed as a result of a chemical reaction. In photosynthesis, the products are glucose and oxygen.
Down
  1. 1. a type of organism whose cells have a nucleus and other specialized structures called organelle
  2. 2. A vital for all living organisms, water is absorbed by plant roots and is a key reactant in the photosynthesis process.
  3. 3. The outer layer of cells covering leaves and stems, providing protection and aiding in gas exchange.
  4. 4. a simple type of organism whose cells do not have a nucleus or other membrane-bound structures
  5. 5. The inner tissue of a leaf, composed of chlorenchyma cells where most photosynthesis occurs. It includes palisade and spongy mesophyll.
  6. 6. Substances that undergo a chemical change in a reaction. In photosynthesis, the reactants are carbon dioxide and water.
  7. 9. A colorless, odorless gas present in the atmosphere, used by plants during photosynthesis as a reactant to produce glucose and oxygen.
  8. 10. Organelles found in plant cells and some algae that conduct photosynthesis, containing thylakoids and stroma
  9. 12. a simple sugar produced during photosynthesis, serving as a primary energy source for plants and other organisms.
  10. 13. a series of chemical reactions where the product of one reaction is consumed by the next reaction
  11. 17. The flat, green parts of a plant where photosynthesis primarily occurs, containing chlorophyll and specialized cells for gas exchange.
  12. 19. Membrane-bound structures within chloroplasts that contain chlorophyll and are the site of the light-dependent reactions of photosynthesis.
  13. 20. space surrounding thylakoids in chloroplasts, where the light-independent reactions (Calvin Cycle) occur.
