http://www.waynesword.net/lmexer8.htm WebAngiosperms: A group of flowering plants that produce seeds enclosed in an ovary, which matures into a fruit. Gymnosperms and angiosperms have reduced gametophytes that are dependent on the sporophyte, while bryophytes and seedless vascular plants have dominant gametophytes. In gymnosperms and angiosperms, the male gametophyte develops within …
WebCorrect option is A) The inner diploid sporogenous tissue of each microsporangium first undergoes mitotic divisions to increase the cell number and then differentiates into microspore/pollen mother cell. Being the product of mitosis in diploid cells, microspore mother cells are diploid i.e. carry two complete sets of chromosomes. WebThe male and female gametophyte structures are present on separate male and female cones in gymnosperms, whereas in angiosperms, they are a part of the flower. Lastly, wind plays an important role in pollination in gymnosperms because pollen is blown by the wind to land on the female cones.
