What happened when we inoculated Rhizobium in wheat field?
No increase in production (nitrogen content of soil remains same)
A lot of increase in production (nitrogen content of soil increases)
Fertility of soil decreases
Fertility of soil increases
A.
No increase in production (nitrogen content of soil remains same)
Rhizobium species is symbiotic nitrogen- fixing bacteria, which occurs in root nodules of legumes. When we inoculated Rhizobium in wheat field, there is no increase in production. Because wheat has no root nodules for fixing nitrogen content. Therefore, nitrogen content of soil will remain same.
Number of chromosomes in an angiospermic plant is 14, then the number of chromosomes in synergid cells will be
