A Correct answer
Explanation

Anthoceros has a sporophyte with a foot and intercalary meristem. Marchantia has gemma cups. Pteris (a fern) has sori covered by a false indusium. Ginkgo is a gymnosperm (embryophytic, tracheophytic, archegoniate).

  4. Anthoceros
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Slime pores are found in :

Correct option is (D), Anthoceros.
Anthoceros grown in moist soil. They have thallus body and found in shady area. Slime pores are present in Anthoceros. 
Hence, option D is correct.

Multiple choice botany kingdom plantae uses of bryophytes introduction to bryophytes cryptogams

The plant body of moss(Funaria) is?

  1. Completely sporophyte

  2. Predominantly gametophyte with sporophyte

  3. Completely gametophyte

  4. Predominantly sporophyte with gametophyte
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In mosses like Funaria, the dominant, free-living, and photosynthetic phase is the gametophyte, while the sporophyte is a smaller structure dependent on it. Thus, the plant body is predominantly gametophyte with a dependent sporophyte.

Multiple choice botany kingdom plantae uses of bryophytes introduction to bryophytes cryptogams

Reduced gametophyte is the important character of _____

  1. Lower cryptogams

  2. Higher cryptogams

  3. Gymnosperms

  4. Angiosperms
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The haploid phase in the life cycle of plants is called Gametophyte. It is a haploid phase. It is well developed in bryophytes and highly reduced in angiosperms.

So, the correct option is 'Angiosperms'.

Multiple choice botany kingdom plantae uses of bryophytes introduction to bryophytes cryptogams

Find set of features related to Funaria
a. Protonema
b. Prothallus
c. Gametophore
d. Thallus body
e. NCC in antheridium
f. Haplodiplontic
g. True plant organs in sporophyte
h. Fragmentation

  1. b, d, e, g

  2. a, d, f, g

  3. a, c, f, g, h

  4. a, c, f, h
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Funaria features include a protonema stage (a), leafy gametophores (c), a haplodiplontic life cycle (f), and propagation via fragmentation (h). Features like prothallus (b) belong to pteridophytes, and true plant organs (g) belong to vascular sporophytes, making option C and others incorrect.

Multiple choice botany kingdom plantae uses of bryophytes introduction to bryophytes cryptogams

Which of the following is incorrect about bryophytes?

  1. Sex organs are multicellular

  2. Water is essential for fertilisation

  3. Meiosis occurs at the time of spore formation

  4. Antherozoids are non-motile
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The statement that antherozoids are non-motile is incorrect because bryophyte male gametes (antherozoids) are biflagellate and motile, requiring water to swim toward the archegonium for fertilization. All other listed statements about bryophytes are true.

Multiple choice botany taxonomy and systematic botany taxonomy and systematics systematics of living world kingdom plantae plant taxonomy classification of biodiversity

Artificial system of classification classifies plants on the basis of

  1. One or very few characters

  2. Phylogenetic trends

  3. Many naturally existing characters

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The major advantage of the artificial system of the classification is considering one or few characters of the plants, so the option (A) is the correct answer.
The phylogenetic trends consideration are all comes under the natural classification, so the option (B) is not the correct answer.
The option (C) refers, many naturally existing characters, which is suitable for the natural classification, not for artificial classification, so the option (C) is also not the correct answer.
