Question
Sexual reproduction in plants provides genetic variation. What are the benefits of this genetic variation? A. If a population is presented with a rapid change in the environment or a chronic new pathogen or herbivore, then genetic variability would increase the chances of survival of the population. B. Sexual reproduction produces less genetic variations which enables a population to co-evolve with other organisms in it's ecosystem. C. Sexual reproduction reduces genetic variations which enables a population to take advantage of different resources in it's ecosystem enabling it to exist in a the same niche as others that use the original resources. D. Sexual reproduction will always produce a more fit organism. Which statement below is not true about asexual reproduction in plants. A. Less energy needed for reproduction as it is strictly mitosis, no sexual organs or gametes need to be produced. B. If the parent plant with it's genome did well in a location then a clone will do equally as well in the same location. C. Reproduction is seasonal and will only take place once a year. D. Vegetative structures may be used to go through dormancy periods (bulbs, tubers, etc) What is one cost to the parent plant of retaining the newly formed offspring on the parent plant until the offspring is established in the ground? A. The parent plants cost is the energy needed to produce sugar to supply to the developing offspring as the offspring has no source for attaining carbohydrates. The parent plants cost is it needs to supply the offspring with CO2 for photosynthesis. The parent plants cost is the energy to grow more roots so it can supply the offspring with water and nutrients. The parent plant needs to defend the offspring from herbivory.Explanation / Answer
