Which of the following statement is incorrect regarding bryophytes?

1. They are dependent on water for sexual reproduction.

2. The main plat body is diploid

3. They usually occur in damp, humid and shaded localities.

4. They play an important role in plant succession on bare rocks.

Mossess and ferns are found in moist and shady places because both

(1) require presence of water for fertilization

(2) do not need sunlight for photosynthesis

(3) depend for their nutrition on microorganisms which can survive only at low temperature

(4) cannot compete with sun-loving plants

(1) Marchantia

(2) Riccia

(3) Funaria

(4) Sphagnum

Examine the figure given below and select the right option giving all the four parts (A, B, C and D) correctly identified:

Gametophyte of Bryophyte is

2. Independent, multicellular.
3. Dependent on sporophyte.
4. Foliose in nature.

Read the following statements reagrding bryophytes and choose the incorrect option.

(1) Gametophytic phase is dominant in life cycle

(2) Fertilisation takes place in presence of water

(3) Zygote undergoes meiosis to produce sporophyte

(4) Sporophyte isphysiologically dependent on gametophyte

Sporophyte in bryophytes is

1. Parasitic on gametophyte

2. Formed by germination of meiospore

3. Specialized to produce gametes

4. Haploid phase

In mosses vegetative reproduction takes place by fragmentation & budding in

1. Primary protonema.

2. Secondary protonema.

3. Rhizoids.

4. Both 1 and 2.

Leafy stage develops from the secondary protonema as a

1. Apical bud

2. Axillary bud

3.Lateral bud

4. Meristem

Male and female gametophytes are independent and free-living in

(1) mustard

(2) castor
