$(1)$ Green plants form the basis of life on Earth.
$(2)$ Photosynthesis is a complex metabolic process.
(N/A) $(1)$ All animals depend directly or indirectly on green plants for their nutrition. Green plants produce food through photosynthesis,which herbivores consume to sustain their lives. Furthermore,the oxygen released during this process is essential for the respiration of all aerobic living organisms.
$(2)$ The process of photosynthesis occurs within the chloroplasts. The light-dependent reaction takes place in the grana,where $ATP$ and $NADPH$ are synthesized. These substances are subsequently utilized in the fixation of $CO_{2}$ during the light-independent reaction (Calvin cycle) to produce glucose. Thus,photosynthesis is a complex anabolic metabolic process.
