Question 1

The basis of biological organization is

Accepted Answer

Submicroscopic molecular level

Answer

The basis of biological organization begins at the most fundamental level, which is the submicroscopic molecular level. This includes atoms, which combine to form complex molecules like DNA, proteins, and lipids. These molecules then assemble into organelles, which in turn form cells, the basic unit of life, leading to higher levels of organization.

Question 2

ICBN is an acronym for:

Accepted Answer

International Code for Botanical Nomenclature

Answer

ICBN stands for the International Code for Botanical Nomenclature. It is a globally recognized set of rules and recommendations that govern the formal scientific naming of plants, fungi, and certain other groups of organisms. Its primary purpose is to ensure stability and avoid ambiguity in botanical names worldwide.

Question 3

An organism's evolutionary history is known as:

Accepted Answer

Phylogeny

Answer

Phylogeny refers to the evolutionary history and relationships among groups of organisms, tracing their lineage and diversification over geological time. It helps in understanding how different species are related to each other through common ancestors. Ontogeny describes the development of an individual organism, while paleontology is the study of fossils.

Question 4

Which of the following is not a true statement?

Accepted Answer

A museum has collection of photographs of plants and animals

Answer

Museums primarily house collections of preserved physical specimens of plants and animals, including skeletons, fossils, and artifacts, for scientific study and public display. While photographs may be used in exhibits, the core collection consists of tangible biological specimens, not just images. The other statements accurately describe the functions of taxonomic keys, botanical gardens, and herbaria.

Question 5

If two plants meet the following criteria, it is certain that they are of the same species:

Accepted Answer

can reproduce freely with each other and form viable seeds

Answer

The biological species concept defines a species as a group of organisms that can naturally interbreed and produce fertile, viable offspring. If two plants can freely reproduce with each other and form viable seeds, it is a definitive indication that they belong to the same species, as they share a common gene pool and reproductive compatibility.
