  1. Short,curved and biflagellate

  2. Short,straight and multi flagellate

  3. Long, straight and biflagellate

  4. Long, curved and biflagellate.

A Correct answer
Explanation

The male gametes, or antherozoids, of Marchantia are small, curved, and biflagellate structures. The two flagella are inserted at the anterior end and help them swim through water to reach the female sex organ (archegonium) for fertilization. This morphology is characteristic of many bryophytes.

Elaters are absent in ___________.

  1. Funaria

  2. Marc

  3. Pellia

  4. Porelia
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Elaters are specialized, hygroscopic cells that aid in spore dispersal and are found in liverworts like Marchantia, Pellia, and Porella. However, they are absent in mosses such as Funaria. Mosses instead rely on peristome teeth within the capsule for regulated spore dispersal.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Matching the botanical structures: Columella aids in spore conduction/support (5), Elater assists in spore dispersal (1), Marsupium provides protection for the sporophyte (2), and Gemma serves as a unit of asexual reproduction (3). This aligns with option D (A-5, B-1, C-2, D-3).

Root epidermis is termed as

  1. $Rhizodermis$
  2. $Endothecium$
  3. $Casparian strip$
  4. $Bundle sheath$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The outermost single layer of cells in a root is called the rhizodermis, also known as the epiblema or root epidermis. It lacks a cuticle and stomata, allowing for the efficient absorption of water and minerals from the soil. It also gives rise to unicellular root hairs.

The female sex organs in Riccia and Funaria is

  1. Antheridium

  2. Paraphyses and capsule

  3. Archegonium

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In Bryophytes, archegonium is the female sex organ. The female shoot arise from the base of the male shoot and called as archegonial branch or archegoniophore. The apex of female shoot is called female receptacle from which cluster of archegonia arise intermixed with non- capitate paraphysis. 

Each archegonium has a stalk, flask-shaped venter and a neck. Venter encloses a basal egg cell (oosphere) and upper smaller venter canal cell. Neck consists of 6 or more neck canal cells (6-11).

Plant body of liverworts is

  1. Thalloid in Porella

  2. Thalloid in Marchantia

  3. Leafy in Marchantia

  4. More than one option is correct
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Liverworts can have diverse plant bodies; some like Marchantia are thalloid, while others like Porella are leafy. Thus, stating Marchantia is thalloid is correct, but claiming it is the exclusive thalloid form or that Marchantia is leafy is incorrect, making the 'more than one' option a distractor since specific statements can vary, but Marchantia specifically has a thalloid body.
