Pine trees and moss show alternation of generations in their life cycle. During the life cycle of pine and moss the sporophyte stage is dominant the gametophyte is diploid meiosis occurs during spore formation seed formation occurs
The life cycle of the flowering plants and the gymnosperms is different in many ways. One way that they are similar however is; They both engage in double fertilization The seed coats for gymnosperms and angiosperms comes from the parent plant and is diploid Both the flowering plants and gymnosperms reproduce by using strobili Both the angiosperms and the gymnosperms are homosporous and produce one type of gametophyte
Which of the following statements is false? Answers: The gametophyte is the dominant form for bryophytes The sporophyte is the dominant form for seedless vascular plants Female angiosperm cones are hard and long-lasting gymnosperm pollen grains are gametophytes that do not form a free-living plant all of the above are true Please explain which one is correct .
Pollination is the act of: transferring pollen grains from the male to the female part of the flower. fusing of gametes. developing a gametophyte from spores. developing a sporophyte from a zygote.
Gymnosperms are heterosporous plants. This means that; They reproduce by using one type of spore Their spores are covered with sporopollenin They produce separate male and female spores
