Multiple choice
  1. Thallophytes

  2. Gymnosperms

  3. Pteridophyta

  4. Bryophyta

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. Riccia

  2. Marchantia

  3. Funaria

  4. Anthoceros

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. Riccia

  2. Funaria

  3. Selaginella

  4. 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.

Multiple choice
  1. Genus and family

  2. Genus and species

  3. Species and sub-species

  4. Phylum and genus

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. cycas

  2. ferns

  3. red algae

  4. brown algae

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. Nepenthes

  2. Utricularia

  3. Dionaea

  4. Monotropa

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. venation

  2. heterophylly

  3. vernation

  4. aestivation

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. Non vascular cryptogams

  2. Non vascular embryophytes

  3. Vascular cryptogames

  4. Vascular embryophytes

Reveal answer Fill a bubble to check yourself
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.  

Multiple choice
  1. Phylum

  2. Class

  3. Kingdom

  4. Series

Reveal answer Fill a bubble to check yourself
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.

Multiple choice
  1. Plant body is either leafy or thalloid.

  2. Flagelleted male gametes

  3. presence of cuticle

  4. multicellular sporangia

Reveal answer Fill a bubble to check yourself
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.
