Answer 1

It is wrong that all plants cant prepare food.
Yellow leafs cant prepare food. Yellow colour of leaf occur because of the absence of chlorophyll, and chlorophyll is responsible for trapping of sunlight for the purpose of photosynthesis. Therefore yellow leaf cannot prepare food.
Leaves of green plant are called food factories because they prepare food for the plant through the process of photosynthesis.
