A researcher is studying the biodiversity of a remote rainforest. Which combination of taxonomical aids would be MOST effective for on-site species identification and documentation?
Monograph, Key, and Preserved specimens
Flora, Catalogue, and Zoological park access
Manual, Key, and Herbarium sheets
Treatise, Monograph, and Botanical garden access
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.
A preserved specimen lacks a label indicating its origin. Which taxonomical aid would be LEAST useful in determining its geographical distribution?
Manual
Catalogue
Key
Herbarium
You discover an unusual marine organism. To determine its taxonomic classification, you consult a key, but it leads to conflicting results with a previously published monograph. Assuming both resources are reliable within their scope, what is the MOST likely explanation for the discrepancy?
The key is outdated and needs revision.
The monograph is too specialized and overlooks common variations.
The organism may represent a newly discovered species or a variant not yet documented in the monograph.
There's a fundamental error in the taxonomic system itself.
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.
In which of the following plants does the stem perform the primary function of photosynthesis?
Ficus
Opuntia
Hibiscus
Mangifera
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 arrangement of vascular bundles in a monocot stem is best described as:
Arranged in a ring
Scattered
Bicollateral
Amphicribral
