Class 11 NEET Biology Morphology Of Flowering Plants Questions Part 1

(d) : An annual plant is one that completes its life cycle in a single season i.e., a seed germinates and the mature plant so produced dies, having produced seeds, within the season. Vivipary on the other hand is the phenomenon of germination of seed or spore in situ on mature plant even before it release. It is not possible for annual plants because in these plants, the mature plant cannot store seeds as it dies after producing seeds.
