Botany is the branch of Biology that focuses on the study of plants , their structure, functions, growth, reproduction, and role in the environment. This category is curated for school students (Classes 6–12) and undergraduate learners to build strong fundamentals with exam-focused clarity.
In this section, you’ll explore:
Plant morphology, anatomy, and physiology explained step-by-step
Reproduction in plants , development, and life cycles
Cell biology, genetics, and biotechnology concepts related to plants
Ecology and plant diversity with real-world relevance
Important questions, MCQs, diagrams, and revision notes for exams
The content is aligned with NCERT , school boards, and UG syllabi , making it highly useful for school exams, NEET preparation, and college assessments . Concepts are explained in simple language with a focus on understanding, not rote learning.
Build a strong foundation in plant sciences and master Botany with confidence.
