male gametes need a way to travel to the egg.
|
|
|
Vascular tissue only works in a moist environment
|
|
|
spores need a way to travel to the egg
|
|
|
They can only absorb oxygen from water
|
Detailed explanation-1: -They are non-vascular plants and absorb water. They depend on diffusion for the movement of water in and out of the plant. They require a moist environment for reproduction.
Detailed explanation-2: -Because water is needed for the sperm cells to reach the egg, this is one of the reasons why moss seem to be more prevalent in wet areas. Once fertilized, the zygote will mature to produce the sporophyte.
Detailed explanation-3: -In many basic plants, water acts as the channel by which gamete transfer takes place. Thus, the correct answer is option (D) water.
Detailed explanation-4: -Some successfully end up on female gametophyte moss plants and are chemically attracted to the archegonium. Each archegonium holds one egg, in a swollen section called the venter. The sperm enter the archegonium through the narrow channel in its neck. Fertilization occurs in the archegonium to form a diploid zygote.
