alleryWhy do bryophytes need water for sexual reproduction?
AThe zygote cannot survive dry conditions
BThe water dissolves required nutrient salts
CThe antherozoids swim through water to egg
DThe capsule splits only in saturated air
Answer & Solution
Correct answer: C. The antherozoids swim through water to egg
Bryophytic antherozoids are biflagellate and must swim through a thin water film from antheridium to archegonium to reach the egg.
Without water, fertilisation fails.
This is why bryophytes are called amphibians of plants.
