1. ROLE OF NITROGEN (N)
Nutrient Foods
, water etc.
Organisms nutrient
obtain is called nutrition
2.
3. The process by which living
organisms obtain food and use
it for growth (metabolism), and
repair is called nutrition. Both
plants and animals need
nutrition throughout their life.
5. PHOTOYSNTHESIS
Plant food production in sunlight .
AUTOTROPHIC;
They can make their food by the process of photosynthesis
. need for nutrient. They are classified by two process.
1; Macronutrients-
2; Micronutrients-
8. ROLE OF
NITROGEN;
Nitrogen is avital
substance.
Nitrogen is major
component of protein ,
hormones , chlorophyll
, vitamins and
enzymes essential for
plants life.
Nitrogen metabolism is a
major factor in stem and
leaf growth.
9. Nitrogen is the key element of amino
acid (NH3) . That is why nitrogen also
play vital role in protein synthesis.
10. proteins are made up of amino acids.
Too much supply of nitrogen can delay flowering
and fruiting.
Deficiency of nitrogen can cause yellowing of the
leave and stunted growth.
