Textbook Question
Chapter 10, Problem 1AC
Many plants car. reproduce sexually or asexually. Strawberries, for example, can reproduce asexually by sending out horizontal stems cabled runners that root and form new plants, or they can reproduce sexually by flowering and producing fruit and seeds. Describe some advantages and disadvantages of each type of reproduction in wild plants. Include in your discussion the important aspects of the environments in which runners and seeds are likely to find themselves.

Why is limiting random sexual reproduction of food crops concerning? Mutations during asexual reproduction decrease plant fitness Consumers do not trust identical-appearing produce Larger portions of the plant populations are susceptible to the same diseases Spores are not viable in an agricultural setting.arrow_forwardAnd some plants as stigma becomes receptive to Polin able to facilitate a pollen tube at a different time from when the anthers ripen. How would this affect the plant reproductive strategy why would this increase diversity in the plants offspring?arrow_forward

- T/F question The fertilization process in plants is a double fertilization process. Over 1/3 of the U.S. food supply comes from the cross-pollination process in plants. The plant hormone auxin inhibits the development of plant lateral roots. Abscisic acid hormone is responsible for the Fall shedding of leaves. Gibberelin is a plant gas hormone. Tropism in plants is a response to seasonal changesarrow_forwardT/F question The limiting factor for plants is phosphorus. Root hairs help to decrease the absorbtive surface area of a plant. Xylem conducts plant sugars and organic molecules. Plant tissues grow from meristem cells that continually divide during the growing season. Primary plant growth involves thickening of the stems and roots. Plants can undergo asexual reproduction without cross-pollination.arrow_forwardThoroughly explain the life cycle of soybean (Glycine max). A hand drawn diagram should form the basis of your answer.
