A Correct answer
Explanation

In bryophytes, the sporophyte is physically attached to and nutritionally dependent on the gametophyte throughout its life.

Multiple choice examples of bryophytes plant kingdom biology

Rhizoids of Funaria are

  1. Colourless, multicellular with transverse septa

  2. Colourless, multicellular with oblique septa

  3. Colourless and unicellular

  4. Coloured and multicellular
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The rhizoids of Funaria are multicellular, branched, and possess oblique septa, which is a key diagnostic feature distinguishing them from other bryophyte rhizoids.

Multiple choice examples of bryophytes plant kingdom biology

Which one of the following is not common between Funaria and Selaginella?

  1. Archegonium

  2. Embryo

  3. Flagellate sperms

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

Funaria is a bryophyte and lacks true roots (it has rhizoids), whereas Selaginella is a pteridophyte and possesses true roots.

Multiple choice examples of bryophytes plant kingdom biology

Meiosis occurs in Funaria in

  1. Archegonial cells

  2. Spore mother cells

  3. Zygotic cells

  4. Antheridial cells
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Meiosis in Funaria occurs within the capsule inside the spore mother cells to produce haploid spores.

  1. $8$
  2. $16$
  3. $32$
  4. $64$
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The peristome in Funaria consists of two rings of 16 teeth each, totaling 32 teeth.

Multiple choice examples of bryophytes plant kingdom biology

The gametophyte of Funaria is

  1. Dioecious and autoicous

  2. Monoecious and autoicous

  3. Monoecious and heteroicous

  4. Dioecious and heteroicous
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Funaria is monoecious (both sex organs on the same plant) and autoicous (sex organs on different branches of the same plant).

Multiple choice examples of bryophytes plant kingdom biology

  2. Multicellular branched oblique septate rhizoids

  3. Branched coenocytic rhizoids

  4. Tuberculate rhizoids
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Funaria is anchored by multicellular, branched rhizoids that feature oblique septa.

Multiple choice examples of bryophytes plant kingdom biology

Sporophyte of Funaria contains columella

  1. Sterile and lateral

  2. Fertile and lateral

  3. Fertile and middle

  4. Sterile and middle
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The columella is a central, sterile column of tissue within the capsule of the Funaria sporophyte.

Multiple choice examples of bryophytes plant kingdom biology

Number of peristome teeth in Funaria capsule is

  1. $16$ in one whorl
  2. $16$ in two whorls
  3. $32$ in two whorls
  4. $32$ in one whorl
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The peristome of Funaria consists of two concentric rings, each containing 16 teeth, for a total of 32 teeth.

Multiple choice examples of bryophytes plant kingdom biology

In Funaria, calyptra is formed from

  1. Capsule

  2. Archegonium

  3. Columella

  4. Antheridium
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • In the majority of bryophytes, embryonic sporophytes elongate gradually to form a foot and a spore-bearing capsule. Calyptra is an enlarged archegonial venter in bryophyte that protects the capsule containing the embryonic sporophyte.
  • Columella is a column of sterile tissues which extends through the theca and are surrounded by spore-producing cells. Antheridium is the male sex organ of algae, fungi, ferns, and other nonflowering plants
So the correct answer is B.
