Q

Why does only 1%-5% of the sunlight reaching the plant transferred into useful chemical energy

A
  1. Most doesn’t hit the plants
  2. Some is reflected off leaf’s surface eg: waxy cuticle
  3. Some passes straight through the leaf without it hitting any chloroplast
  4. Only part of the light is useful and is absorbed by chlorophyll
