Screening is not recommended for women under the age of 21. In 2010, recent Pap testing (within three years) dropped among women aged 30 years and older without a hysterectomy, primarily due to declines among women aged 65 years and older (from 73.5 percent in 2000 to 64.5 percent).
The most substantial growth over the life cycle of the plant occurs in the vegetative stage and will continue unless hindered by a change in environment or lack of water and nutrients. Third Stage â Reproductive, Flowering and Fruit. The final stage of the plant growth is the reproductive stage.
Lesson Summary. 1  All plants have a life cycle with alternation of generations. 2  In nonvascular plants, the gametophyte generation is dominant. 3  In vascular plants, the sporophyte generation is dominant. 4  In seed plants, the gametophyte generation takes place in a cone or flower, which forms on the mature sporophyte plant.he flower in Figure above is obviously an innovation in the angiosperm life cycle. Flowers form on the dominant sporophyte plant. They consist of highly specialized male and female reproductive organs. Flowers produce spores that develop into gametophytes.
