- T/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.QUESTION 10 Which is true regarding plant reproduction? Self-pollination produces offspring genetically identical to the parent modified organs, such as corms and bulbs, are produced as a result of sexual reproduction cross-pollination allows plant populations to survive in unstable environments plants do not reproduce asexually vectors such as flies carry plant spores to new locationsOwners and managers of plant nurseries have to plan lighting schedules lor a long-day plant that will flower in February. What lighting periods will be most effective? What color of light should be chosen?
