Answer:
Sexual reproduction in ‘Spirogyra is morphologically’ characterised by C) Isogamy.
Explanation:
Sexual reproduction is the fusion of male gametes and female gametes. Sexual reproduction may be divided into isogamy, anisogamy, and oogamy.
‘Anisogamy’ is the fusion of 2 gametes of dissimilar size, ‘isogamy is the fusion’ of 2 similar gametes and ‘oogamy is the fusion’ of one female gamete which is very big and the male gamete which is very small.
