GATE 2019 Syllabus for Botany

GATE 2019 – In their graduate fields, to test the performance and understanding capability of students Graduate Aptitude Test in Engineering (GATE) which is a national level exam is being conducted. In this test is useful for the admissions. On behalf of the  National Coordination Board, GATE exam is jointly conducted by the seven IITs (Indian Institute of Technology) and IISc (Indian Institute of Science)  – GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India. In many of the government and private organizations, GATE score is important for recruitment. GATE score is compulsory for many private organizations.


About Botany

The branch of biology and the science of plant life is called Botany. In other words, we call it as plant science(s), plant biology or phytology. For a few applied sciences as agriculture, horticulture, and forestry, the principles and findings of botany have provided the basis.  Research topics include the study of plant structure, growth and differentiation, reproduction, biochemistry and primary metabolism, chemical products, development, diseases, evolutionary relationships, systematics, and plant taxonomy. Modern botany is a broad, multidisciplinary subject with inputs from most other areas of science and technology.
