Bryophytes are of great ecological importance.Reason :- Bryophytes help in colonisation (succession) on bare rocks/soil.Both Assertion and Reason are true and Reason is the correct explanation of Assertion.Both Assertion and Reason are true but Reason is NOT the correct explanation of Assertion.Assertion is true but Reason is false.Assertion is false but Reason is true.

Bryophytes might colonize many more environments and be much more abundant if theyMultiple Choicecould be more tolerant to changes in temperature.had vascular tissues.were not so easily outcompeted.reproduce more frequently.

Study the two statements labeled as Assertion (A) and Reason (R) and choose the correct answer. Assertion (A): Trees prevent soil erosion. Reason (R): Fallen leaves decompose and form organic matter, which helps to prevent soil erosion.A is false but R is true.A is true but R is false.Both A and R are true and R is the correct explanation of A.Both A and R are true but R is not the correct explanation of A.

Which of the following is true about bryophytes?a. Some of them are thalloid.b. They possess archegonia.c. They are chlorophyllous

Directions: In the following questions, a statement of assertion is followed by a statementof reason.Mark the correct choice as:(a) If both Assertion and Reason are true and Reason is the correct explanation of Assertion.(b) If both Assertion and Reason are true but Reason is not the correct explanation ofAssertion.(c) If Assertion is true but Reason is false.(d) If both Assertion and Reason are false.1.Assertion(A): Chloroplasts mostly occur in mesophyll cells along their walls inside theleaves.Reason(R) : The membrane system of chloroplast is responsible for trapping the light energyand also for the synthesis of ATP and NADPH.2. Assertion(A) : The offspring produced by sexual reproduction is likely to adjust better inenvironmental fluctuation.Reason (R) : During the fusion of gametes there is mixing of genetic material from twoparents

Given below are two statements.One is labeled Assertion(A) and the other is labeled Reason(R).Assertion (A): In bryophytes, the sporophyte is not free-living but attached to the gametophyteReason (R): The sporophyte derives nourishment from the photosynthetic gametophyte, which is the main plant body and is haploid.
