Which of the following is NOT a fundamental characteristic of living organisms according to NCERT?
Growth
Reproduction
Metabolism
Entropy
A scientist observes a newly discovered entity that exhibits growth, reproduction, and response to stimuli but lacks a defined cellular structure. Based on NCERT's definition of life, which statement is most accurate?
The entity is unequivocally a living organism due to exhibiting key life processes.
The entity is a non-living entity as all life must possess a cellular structure.
The entity's status as a living organism is ambiguous as it lacks a key defining feature.
The entity represents a pre-cellular life form demonstrating the evolution of life.
Which hierarchy of biological organization is correctly ordered from simplest to most complex according to NCERT?
Organelle, Macromolecule, Cell, Tissue, Organ, Organ System, Organism
Macromolecule, Organelle, Cell, Tissue, Organ System, Organ, Organism
Macromolecule, Organelle, Cell, Tissue, Organ, Organ System, Organism
Cell, Macromolecule, Organelle, Tissue, Organ, Organ System, Organism
According to NCERT, the most defining characteristic distinguishing living organisms from non-living matter is:
The ability to respond to external stimuli
The capacity to perform metabolic reactions
The presence of self-replicating molecules enabling inheritance and evolution
The exhibition of growth and development
Which branch of biology specifically deals with the identification, nomenclature, and classification of organisms as described in NCERT?
Ecology
Physiology
Taxonomy
Morphology
Which statement best describes the relationship between biodiversity and taxonomy according to NCERT?
Biodiversity hinders taxonomic efforts by creating an overwhelming number of organisms to classify.
Taxonomy and biodiversity are independent fields with minimal interaction.
Taxonomy provides the framework for organizing and understanding the vast diversity of life.
Biodiversity is a subset of taxonomy, focusing specifically on species richness.
Which of the following is NOT a defining characteristic of living organisms?
Growth
Metabolism
Reproduction
Crystallisation
Which level of biological organization is represented by a functional unit of an organ?
Cell
Tissue
Organ
Organ System
The process of maintaining a constant internal environment despite external changes is called:
Adaptation
Evolution
Homeostasis
Metabolism
