Sample Tamil Nadu HSE First Year Botany Practice Questions

Try these sample questions to review concepts for the Tamil Nadu HSE First Year Botany exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1The basic unit of classification and the lowest taxonomic rank commonly used for a species name is the:
A.Species
B.Kingdom
C.Phylum
D.Family
Explanation: Species is the basic unit of classification and the lowest principal rank in the Linnaean hierarchy used in binomial nomenclature.
2Who proposed the five-kingdom classification system that separates Monera, Protista, Fungi, Plantae, and Animalia?
A.Carolus Linnaeus
B.R.H. Whittaker
C.Ernst Haeckel
D.Carl Woese
Explanation: R.H. Whittaker (1969) proposed the five-kingdom system based largely on cell type, body organisation, mode of nutrition, reproduction, and phylogenetic relationships.
3In binomial nomenclature, the scientific name of mango is written as:
A.Mangifera Indica
B.mangifera indica
C.Mangifera indica
D.MANGIFERA INDICA
Explanation: In binomial nomenclature the genus is capitalised and the specific epithet is lowercase; both are italicised (or underlined): Mangifera indica.
4Viruses are generally not placed in the five-kingdom classification mainly because they:
A.Are always photosynthetic
B.Have true nuclei like fungi
C.Reproduce only by binary fission like bacteria
D.Lack cellular organisation and are obligate parasites
Explanation: Viruses are acellular, possess either DNA or RNA in a protein coat, and replicate only inside living host cells, so they fall outside the cellular five-kingdom framework.
5Which group of algae is characterised by floridean starch as a reserve food and often red pigments such as phycoerythrin?
A.Rhodophyceae (red algae)
B.Chlorophyceae (green algae)
C.Phaeophyceae (brown algae)
D.Cyanobacteria only
Explanation: Rhodophyceae (red algae) store floridean starch and typically contain phycoerythrin (and phycocyanin), giving many species a red colour.
6The plant body of a bryophyte is typically a thallus or leafy gametophyte that is:
A.Independent sporophyte-dominant like a fern tree
B.Haploid and nutritionally independent while the sporophyte is dependent
C.Diploid and free-living without any gametophyte
D.Always fully vascular with xylem and phloem
Explanation: In bryophytes the dominant generation is the haploid gametophyte; the diploid sporophyte is attached to and nutritionally dependent on the gametophyte.
7Homosporous pteridophytes produce:
A.Two types of spores: microspores and megaspores
B.Seeds enclosed in fruits
C.Only one type of spore that grows into a bisexual gametophyte
D.Pollen grains only, never spores
Explanation: Homospory means production of a single morphological spore type; the resulting gametophyte is often bisexual (prothallus with both antheridia and archegonia).
8Gymnosperms are seed plants in which the ovules are:
A.Enclosed within an ovary that becomes a fruit
B.Always underwater and free-floating
C.Borne only on underground rhizomes
D.Naked and not enclosed in an ovary
Explanation: Gymnosperm means "naked seed": ovules (and later seeds) are exposed on megasporophylls/cones and not enclosed in an ovary.
9Double fertilisation is a characteristic feature of:
A.Angiosperms
B.Bryophytes only
C.Pteridophytes only
D.Gymnosperms only
Explanation: In angiosperms, one male gamete fuses with the egg (syngamy) and the other with the central cell (triple fusion), producing the zygote and endosperm—double fertilisation.
10Which algal group includes kelps and often has air bladders and a body differentiated into holdfast, stipe, and frond?
A.Chlorophyceae
B.Phaeophyceae
C.Rhodophyceae
D.Charophyceae only as the sole correct class name here
Explanation: Brown algae (Phaeophyceae) include large kelps; many show holdfast-stipe-frond organisation and air bladders for buoyancy.
