Algae and fungi have simple body organization and are involved in asexual reproduction during favourable conditions, as it is faster and becausegamete formation during sexual reproduction requires a lot of energy expenditure. At the onset of adverse conditions they switch tosexual mode of reproduction, to ensure that there is variations created which can probably survive the ensuing hard times. Sexual reproduction in these organismsoccurby the formation ofzygospores. 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'.
