Question

Water is essential for Bryophyte, because
A. For fertilization and homosporous nature
B. Water should be filled in archegonium for fertilization
C. Water is necessary for the movement of sperm
D. For dissemination spores

Answer 1

Hint: As we know that water is one of essential compounds which plays a significant role in the transportation of nutrients in plants. In absence of enough water the plants droop, thus, we can say that water helps the plant to stand. The water molecules help the plants in carrying the nutrients and sugar throughout the plant. We know that the bryophytes are nonvascular plants, they choose moist environments but they can endure in drier atmospheres. However, they are limited in size.

Complete answer:
Sexual reproduction involves the combination of genes from two different parents to produce offspring with a genetic makeup similar to but different from each parent.
In Bryophytes the process of sexual reproduction requires the formation of male gametes(sperm), female gametes (eggs), and some ways of getting the sperms to the eggs.
The formation of gametes occurs on the gametophytes.
Sexual reproduction in bryophytes requires water. Thus, it is the water that carries the sperm to the egg.
Archegonia are tiny flask-like structures in which eggs are produced.
Dissemination of spores occurs by air currents, once they settle in the moist place they germinate.
Homosporous nature is the life history that occurs in all bryophytes and most pteridophytes.
Hence, the correct answer is option C.

Additional Information:
Water plays a significant role in the completion of the life cycle in Bryophytes.
Bryophytes are said to be the amphibians of the plant kingdom.
Bryophytes are multicellular and form tissue.
They are transitional between aquatic plants such as algae and higher plants such as trees.

Note:
Bryophytes are nonvascular plants, prefer moist habitats but they can survive in drier environments. In Bryophytes the process of sexual reproduction requires the formation of male gametes(sperm), female gametes( eggs), and some ways of getting the sperms to the eggs. Bryophytes are dependent on water for survival and reproduction. Water is necessary for sexual reproduction in Bryophytes as sperms swim to the eggs to fertilize it.
