(d) In Pinus, male and female cones are borne on different trees

  1. $a$ and $c$
  2. $a$ and $d$
  3. $b$ and $c$
  4. $a$ and $b$
Reveal answer Fill a bubble to check yourself

Which is true about mosses?

  1. Dominant and independent sporophyte

  2. Archegonia produce many eggs

  3. Antherozoids require water for fertilization

  4. Antherozoids are multiflagellate
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Mosses require water for fertilization so that the biflagellate antherozoids can swim to the archegonium to fertilize the single egg. Their sporophyte is dependent on the gametophyte, and archegonia produce only a single egg.

Which one of the following is a fat-soluble vitamin and its related deficiency disease ?

  1. Calciferol Pellagra

  2. Ascorbic acid Scurvy

  3. Retinol Xerophthalmia

  4. Cobalamine Beri-beri
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Retinol (Vitamin A) is a fat-soluble vitamin, and its deficiency causes xerophthalmia. Calciferol (Vitamin D) deficiency causes rickets, while ascorbic acid and cobalamine are water-soluble vitamins.

Peat moss is 

  1. Sphagnum

  2. Funaria

  3. Riccia

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

Sphagnum is the scientific name of peat moss. It is a moss. It is also called as bog moss. It has high pH. Hence, it is used for plants growing in acidic condition, such as blueberries. It helps in moisture absorption from the soil.

Thus, the correct answer is option A.

List-I List-II
a. Marchantiales $1$. Neck of arch gonium composed of five vertical rows of cells
b. Leafy Jungerm anniales $2$. Absence of elaters in capsule

A Correct answer
Explanation

Marchantiales are characterized by the presence of scales on the thallus. Leafy Jungermanniales have archegonial necks composed of five vertical rows of cells. In Anthocerotales, the archesporium arises from the amphithecium, and in Funariales, elaters are absent in the capsule.

In which one of the following bryophytes does archesporium arise from endothelium?

  1. Marchantia

  2. Funaria

  3. Sphagnum

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

In Marchantia, the entire endothecium of the developing sporophyte differentiates into the archesporium (sporogenous tissue), which later gives rise to spore mother cells and elaters. In contrast, in Anthoceros and Sphagnum, the archesporium is derived from the amphithecium.

Choose the correct answers from the alternatives given.
In which one of the following plants sporophyte is completely dependent on gametophyte?

  1. Riccia

  2. Funaria

  3. Angiosperms

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

Plant body of bryophyte is differentiated than that of algae and it is thallus like and prostate and effect. The main plant body is haploid and is known as gametophyte. There is a multicellular body which is known as sporophyte which is not free living and is attached to the gametophyte and derives nourishment from it.

So, the correct answer is Riccia which is a bryophyte.
