The spores produced in capsule in moss, germinate to form haploid structure referred as __________.
Important Questions on Plant Kingdom
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.
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 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
A) The female sex organs of Angiosperms are called strobilus.
B) The fusion of motile male gamete with non-motile egg is called zooidogamy.
C) Some algae are in association with animals.
D) Archegonium is flank shaped male sex organ with single cell.
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:
(A) Elaters
(B) Indusium
