Design speeds for frontage roads are a factor in the design of the roadway. For consistency, design speeds should be used that match values used for collector streets or highways. For urban frontage roads, the desirable design speed is 50 mph [80 km/h] and the minimum design speed is 30 mph [50 km/h].
Different plants reproduce in different ways. Some plants reproduce asexually, others do use a type of sexual reproduction. Flowering plants in particular reproduce both sexua â¦ lly and asexually. Reproduction in flowering plants involves the production of gametes, the transfer of the male gametes to the female ovules is through pollen.
Parts of a Flower. A flowering plant is an angiosperm, which is any plant that produces a flower or fruit. The sole purpose of the flower is to allow the plant to reproduce. Each part of the flower plays a role in the steps of reproduction. Some flower parts are sterile but still aid in the process of reproduction. There are male gametes and female gametes.
