Question

Most bryophytes require a damp habitat because

• A. They do not have a cuticle.
• B. They lack gametangia to protect their developing embryo.
• C. Their sporophyte generation, which lacks vascular tissue, is dependent on the gametophyte.
• D. Flagellated sperm must swim to fertilize the egg.

Answer 1

The correct option is D Flagellated sperm must swim to fertilize the egg.

Bryophytes are known as the amphibians of the plant Kingdom. These exist and live on the land but they require water and damp condition for their reproductiion. Water is necessary for the bryophytes as the flagellated sperm needs water to swim and then fertilize the eggs. The egg is non motile and the sperm cannot swim in dry conditions without water.

So, the correct option is 'flagellated sperm must swim to fertilize the egg'
