Plant Biology and Classification Questions
-
angiospermae
-
gymnospermae
-
monocotyledoneae
-
dicotyledoneae
-
spermatophyta
-
solanaceae
-
poaceae
-
malvaceae
-
liliaceae
-
Thallophytes
-
Gymnosperms
-
Pteridophyta
-
Bryophyta
A
Correct answer
Explanation
Thallophyta is a division of the plant kingdom that includes organisms with a simple, undifferentiated plant body (thallus), which encompasses both algae and fungi.
-
Lycopodium
-
Selaginella
-
Marsilea
-
Pteridium
B
Correct answer
Explanation
Selaginella lepidophylla is commonly known as the resurrection plant because it can survive extreme desiccation by curling into a ball and appearing dead, then 'resurrecting' when exposed to water.
-
leptosporangiate
-
eusporangiate
-
unisporangiate
-
megasporangiate
A
Correct answer
Explanation
Leptosporangiate ferns are those in which the sporangium develops from a single superficial cell. Eusporangiate ferns develop from a group of initial cells.
-
Riccia
-
Marchantia
-
Funaria
-
Anthoceros
A
Correct answer
Explanation
Riccia has the simplest sporophyte among bryophytes, consisting only of a capsule with no foot or seta. Other options like Funaria and Anthoceros have more complex sporophytes.
-
Riccia
-
Funaria
-
Selaginella
-
Dryopteris
C
Correct answer
Explanation
A ligule is a small, scale-like outgrowth found on the leaves of certain pteridophytes. It is a characteristic feature of the genus Selaginella.
-
Genus and family
-
Genus and species
-
Species and sub-species
-
Phylum and genus
B
Correct answer
Explanation
Binomial nomenclature, introduced by Linnaeus, provides a two-part scientific name for every organism. The first part represents the genus and the second part represents the species.
-
cycas
-
ferns
-
red algae
-
brown algae
B
Correct answer
Explanation
Pteridophytes are the first vascular plants to evolve on land. Among the options provided, ferns are the most representative group of vascular plants.
-
Riccia
-
Funaria
-
Spirogyra
-
Dryopteris
B
Correct answer
Explanation
The protonema is a filamentous, juvenile stage in the life cycle of mosses, such as Funaria, which develops directly from the germinating spore.
-
Nepenthes
-
Utricularia
-
Dionaea
-
Monotropa
D
Correct answer
Explanation
Monotropa (Indian pipe) is a non-photosynthetic plant that obtains nutrients from decaying organic matter, making it a saprophyte. Nepenthes, Utricularia, and Dionaea are insectivorous plants.
-
venation
-
heterophylly
-
vernation
-
aestivation
B
Correct answer
Explanation
Heterophylly is the phenomenon where a single plant exhibits different leaf shapes or sizes, often due to environmental factors or developmental stages. Venation refers to the pattern of veins, while vernation is leaf arrangement in the bud.
-
Non vascular cryptogams
-
Non vascular embryophytes
-
Vascular cryptogames
-
Vascular embryophytes
A
Correct answer
Explanation
Bryophytes are also called non vascular cryptogams because vascular tissues are absent in them.Bryophyte is a traditional name used to refer to all embryophytes (land plants) that do not have true vascular tissue and are therefore called "non-vascular plants".Some bryophytes do have specialized tissues for the transport of water. Since these do not contain lignin, they are not considered to be true vascular tissue.
-
Phylum
-
Class
-
Kingdom
-
Series
C
Correct answer
Explanation
Kingdom is the largest unit of biological classification. In the animal kingdom, the term phylum is used instead of division , in the plant kingdom.
-
Plant body is either leafy or thalloid.
-
Flagelleted male gametes
-
presence of cuticle
-
multicellular sporangia
A
Correct answer
Explanation
Pteridophytes differ from bryophytes in having plant body is either leafy or thalloid.Plant body is differentiated into root, stem and leaves
The cells in plant body are diploid.
