Prepare for NEET with Botany-specific practice questions. Covering all major Botany chapters, this is perfect for your NEET Biology needs.
Which statement correctly explains the relationship between taxonomic categories and phylogenetic classification?
Taxonomic categories are arbitrary and have no relationship to phylogeny.
Taxonomic categories always perfectly match the branching patterns of phylogenetic trees.
Taxonomic categories ideally reflect evolutionary relationships revealed through phylogenetic analysis.
Phylogenetic analysis is used to create taxonomic categories, but they don't necessarily reflect evolutionary relationships.
Polyphyletic groups are problematic in taxonomy because they:
Include all descendants of a common ancestor.
Include the most recent common ancestor and all its descendants.
Do not include the most recent common ancestor of all members.
Represent a single evolutionary lineage.
The 'Five Kingdom Classification' system proposed by R.H. Whittaker does NOT primarily consider which of the following criteria?
Cell structure (prokaryotic vs. eukaryotic)
Mode of nutrition (autotrophic vs. heterotrophic)
Thallus organization (unicellular vs. multicellular)
Detailed evolutionary relationships based on genetic analysis
Which statement BEST describes the relationship between a monograph and a flora?
A monograph is a summarized version of a flora, focusing on key species.
A flora is a collection of monographs from a specific region.
A monograph provides an in-depth study of a specific taxonomic group, while a flora documents all plant species in a given geographical area.
Both are interchangeable terms for comprehensive taxonomic treatments.
Which of the following statements regarding the anomalous secondary growth in Boerhaavia is INCORRECT?
A variant of cambium outside the vascular bundles
Concentric rings of secondary vascular bundles
Presence of medullary bundles
Inverted vascular bundles
In a dicot stem undergoing secondary growth, which tissue is primarily responsible for the increase in girth?
Cork Cambium
Vascular Cambium
Apical Meristem
Intercalary Meristem
The 'open' vascular bundles found in dicot stems are characterized by:
Scattered arrangement of xylem and phloem with no cambium.
The presence of cambium between xylem and phloem, allowing for secondary growth.
Joint, collateral arrangement of xylem and phloem with no cambium.
Concentric arrangement of xylem and phloem.
Which of the following is NOT a function of lenticels?
Gaseous exchange
Transport of water and minerals
Transpiration
Removal of excess water in some plants
The bulliform cells in the leaves of certain grasses play a crucial role in:
Increasing the photosynthetic surface area.
Secreting resinous substances for protection.
Leaf rolling and unfolding in response to water availability.
Storing water for use during drought.
Which of the following combinations of floral whorls is ALWAYS present in a complete flower, irrespective of its symmetry or sexuality?
Calyx, corolla, androecium, and gynoecium
Calyx and corolla only
Androecium and gynoecium only
Calyx, corolla, and androecium only
