An attribute found in plants but not animals is
Metabolism
Sexual reproduction
Autotrophy
Asexual reproduction
Which of the following is less general in characters as compared to genus
Species
Family
Class
Division
Consider the following two statements:
I. In the single-celled organisms, we are not very clear about the usage of the two terms – growth and reproduction.
II. When it comes to unicellular organisms like bacteria, unicellular algae or amoeba, reproduction is synonymous with growth, i.e., increase in number of cells.
Both I and II are true and II explains I
Both I and II are true but II does not explain I
I is true but II is false
Both I and II are false
I. Cellular organization of the body is the defining feature of life forms.
II. Metabolic reactions cannot be demonstrated outside the body in cell-free systems.
The most obvious & complicated feature of all living organisms is:
The ability to sense their surroundings or environment and respond to these environmental stimuli.
Reproduction - sexual or asexual - for production of progeny of own kind.
The ability to growth in size due to cell division.
Presence of complex organs systems such as digestive and nervous system.
The scientific term for biological classification categories is the:
Taxon
Phylum
Domain
What is meant by the "species problem"?
The exact definition of species is still controversial.
The exact mechanisms of speciation is not known.
The number of species present is much more than identified species.
The extinction of species is taking place at an alarming rate.
Which of the following taxonomic categories are correctly matched to their standard termination of names with respect to biological classification of plants?
I, II, IV
I, II, III
II, III, IV
I, II, III, IV
Consider the following statements:
I. Higher the taxa, more are the characteristics that members whithin the taxon share.
II. Lower the category, greater is the difficulty of determining the relationship to other taxa at the same level.
Of the two statements:
I is false but II is true
Both I and II are true

Which one of the following is not a correct statement?
Herbarium houses dried, pressed and preserved plant specimens
Botanical gardens have collection of living plants for reference
A museum has collection of photographs of plants and animals
Key is a taxonomic aid for identification of specimens
Two plants can be conclusively said to belong to the same species if they:
can reproduce freely with each other and form viable seeds
have more than 90 percent similar genes
look similar and possess identical secondary metabolites
have same number of chromosomes
Which one of the following is common to multicellular fungi, filamentous algae and protonema of mosses?
Diplontic life cycle
Members of kingdom-Plantae

Which one of the following animals is correctly matched with its particular named taxonomic category?
(1)
Cuttlefish
–
Mollusca, a class
(2)

tigris, the species
Nicotiana sylvestris flowers only during long days and N.tabacum flowers only during short days. If raised in the laboratory under different photoperiods, they can be induced to flower at the same time and can be cross-fertilized to produce self-fertile offspring. What is the best reason for considering N.sylvestris and N.tabacum to be separation species?
They cannot interbreed in nature
They are reproductively distinct
They are physiologically distinct
They are morphologically distinct
The taxon which includes related species is
class
order
family
genus
Classification is not associated with
