Explanation:
WHAT IS PLANT NUTRITION?
As you know that all living organisms require food to survive, grow and reproduce
so every organism takes in food and utilizes the food constituents for its
requirements of growth. A series of processes are involved in the synthesis of food
by plants, breaking down the food into simpler substances and utilization of these
simpler substances for life processes. Nutrition in plants may thus be defined as
a process of synthesis of food, its breakdown and utilisation for various functions
in the body.
1. Autotrophic Nutrition-
Green plants obtain energy from sunlight and therefore are called photoautotrophs. The process of synthesizing food
in plant in the presence of sunlight is called photosynthesis
2. Heterotrophic nutrition-
Certain non green organisms like fungi and many bacteria fail to synthesize their
own organic nutrients from inorganic substances. These organisms are thus
dependent on some other external sources for their organic nutrition. Such plants
are called heterotrophic plants and the mode of nutrition is called heterotrophic
nutrition.
