This Botany section covers the plant biology side of the biology syllabus, from plant structure and function to classification and reproduction. Each question set lets you check how well you remember the concepts and spot the areas worth revising again. Useful for regular topic revision as well as pre-exam practice.
Blood group AB is an example of co-dominance (both A and B are expressed) and multiple allelism (three alleles: IA, IB, and i). This follows from NCERT principle where relation explains outcome clearly for students.

The Krebs cycle does generate ATP through substrate-level phosphorylation. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Cytokinins delay leaf senescence by mobilizing nutrients and promoting ll division. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Biodiversity hotspots are regions with exceptionally high species richness and many endemic species, making them critical for conservation. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
In co-dominance, both alleles contribute equally to the phenotype, instead of one suppressing the other. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Light-harvesting complexes absorb light and transfer energy to reaction nters for photosynthesis. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Fucoxanthin, a xanthophyll pigment, gives brown algae (Phaeophyceae) their characteristic color. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
The complete disintegration of the nuclear envelope marks the transition from prophase to metaphase in mitosis. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Cilia are usually shorter and more numerous than flagella, which are longer and fewer in number. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Cyanobacteria are prokaryotic and lack a well-defined nucleus. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Cymose inflorescence has a basipetal arrangement, where older flowers are at the top and younger ones at the base. This follows from NCERT principle where relation explains outcome clearly for students.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept, Topic: Plant structure, physiology and applications.
Hemizygosity explains why males (XY) express X-linked recessive traits more frequently, as they have only one X chromosome. This follows from NCERT principle where relation explains outcome clearly for students.
