Important Questions on Plant Kingdom
(A) Elaters
(B) Indusium
(C) Agar
Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : The first stage of gametophyte in the life cycle of moss is protonema stage.
Reason (R): Protonema develops directly from spores produced in capsule.
In the light of the above statements, choose the correct answer from the options given below:
Match the plant with the kind of life cycle it exhibits:
| List-I | List-II | ||
| (a) | Spirogyra | (i) | Dominant diploid sporophyte vascular plant, with highly reduced male or female gametophyte |
| (b) | Fern | (ii) | Dominant haploid free-living gametophyte |
| (c) | Funaria | (iii) | Dominant diploid sporophyte alternating with reduced gametophyte called prothallus |
| (d) | Cycas | (iv) | Dominant haploid leafy gametophyte alternating with partially dependent mutlicellular sporophyte |
Choose the correct answer from the options given below:
Match the following lists:
| List- | List- | ||
| A. | Protonema | Useful in spore dispersal | |
| B. | Circinate venation | Coiling of young leaves in Pteridophytes | |
| C. | Elaters | Storage food in Rhodophyceae | |
| D. | Floridean starch | Juvenile stage of Bryophytes | |
| Naked ovules |
The correct match is
Assertion (A): In evolution, the distribution of Bryophytes and Pteridophytes, was limited.
Reason (R) : The need for water for the transportation of male gametes and fertilization limited their distribution.
The correct option among the following is:
Assertion (A): Bryophytes are the amphibians of the plant kingdom.
Reason (R): They are found in swamps and areas, where water and land meet.
