Study Notes
IISER Aptitude Test: Biology
Overview
- The IISER Aptitude Test is a national-level entrance exam for admission to the Indian Institutes of Science Education and Research (IISERs)
- The biology section tests the candidate's understanding of fundamental concepts in biology, chemistry, and physics
Biology Syllabus
-
Unit 1: Diversity of Living Organisms
- Classification of living organisms ( kingdoms, phyla, classes, orders, families, genera, species)
- Characteristics of different kingdoms (Monera, Protista, Fungi, Plantae, Animalia)
- Major groups of organisms (bacteria, viruses, protozoa, fungi, plants, animals)
-
Unit 2: Cell Biology
- Cell structure and function (cell membrane, cell wall, cytoplasm, nucleus, organelles)
- Cell division (mitosis, meiosis)
- Cell cycle and its regulation
-
Unit 3: Genetics and Evolution
- Mendel's laws of inheritance (laws of segregation, independent assortment, dominance)
- Chromosomal theory of inheritance
- Mutations and genetic variation
- Evolution (mechanisms, evidence, and principles)
-
Unit 4: Plant Biology
- Plant structure and function (roots, stems, leaves, flowers, fruits)
- Plant physiology (photosynthesis, respiration, transpiration)
- Plant growth and development
-
Unit 5: Animal Biology
