This Botany section gathers practice questions on plant life, including structure, physiology, reproduction, classification, genetics and ecology. Use it to test what you remember from each topic and to spot the areas worth going back over.
In glycolysis, substrate-level phosphorylation directly generates 4 ATP molecules. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Fungi lack chlorophyll and obtain nutrients through absorption, either as saprophytes or parasites. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Whorled phyllotaxy is not common in dicots; it is a special arrangement found in some plants like Alstonia. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Bryophytes require water for sexual reproduction, earning them the name 'amphibians of the plant kingdom'. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Plant Kingdom, Topic: Classification and salient features of plant groups.
The plasma membrane is selectively permeable and regulates the movement of substances in and out of the ll. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Morphology and Anatomy of Flowering Plants, Topic: Plant structure and tissue systems.
The principle of segregation ensures that alleles separate during gamete formation, allowing each gamete to receive only one allele of a gene pair. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Biology - Botany portion covering relevant concept.
Ethylene is used to induce flowering and synchronize fruiting in pineapple plantations. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Morphology and Anatomy of Flowering Plants, Topic: Plant structure and tissue systems.
A grazing food chain starts with living producers like grass or algae and is consumed by herbivores and carnivores. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Plant Kingdom, Topic: Classification and salient features of plant groups.
Peptidyl transferase is an enzyme that catalyzes the formation of peptide bonds between amino acids during translation. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Morphology and Anatomy of Flowering Plants, Topic: Plant structure and tissue systems.
Recombinase facilitates crossing over during the pachytene stage of prophase I in meiosis. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.

Legumes are dehiscent fruits that split open at maturity to release seeds. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
Ref: NCERT Biology Textbook for Class XI and XII (Botany section), Chapter: Morphology and Anatomy of Flowering Plants, Topic: Plant structure and tissue systems.
In the Z scheme, electrons move from PSII to PSI via an electron transport chain, enabling ATP and NADPH production. This follows from NCERT principle where the relation explains the outcome clearly for students in simple steps.
