Regarding assertion and reason, select the correct option
Assertion [A]: Algae and fungi shift to sexual method of reproduction at the onset of adverse conditions.
Reason [R]: Sexual reproduction results in the formation of zygospore in algae and fungi.
Regarding assertion and reason, select the correct option
Assertion [A]: Algae and fungi shift to sexual method of reproduction at the onset of adverse conditions.
Reason [R]: Sexual reproduction results in the formation of zygospore in algae and fungi.
The correct option is C A is false but R is true
Algae and fungi have simple body organization and are involved in asexual reproduction during favourable conditions, as it is faster and because gamete formation during sexual reproduction requires a lot of energy expenditure. At the onset of adverse conditions they switch to sexual mode of reproduction, to ensure that there is variations created which can probably survive the ensuing hard times. Sexual reproduction in these organisms occur by the formation of zygospores. A zygospore remains dormant while it waits for environmental cues, such as light, moisture, heat, or chemicals secreted by plants. When the environment is favorable, the zygospore germinates, meiosis occurs, and haploid vegetative cells are released. Therefore, the 'Assertion' statement is correct, the 'Reason' statement is correct and 'Reason' explains the 'Assertion'.
