Down
- 1. Proteins in cell membranes that allow the passive transport of ions.
- 2. Specialized cells in C4 plants where the Calvin cycle takes place.
- 4. Process by which water moves across a semipermeable membrane, critical for plant water uptake.
- 5. Fluid-filled space inside the chloroplast where the Calvin cycle (carbon reactions) occurs.
- 7. Yellowing of leaves, often indicating a nutrient deficiency.
