- Please choose the right option.arrow_forwardCan you answer all the parts to this question regarding the diagramarrow_forwardThe drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?arrow_forward

- Plants and animals usually battle each other; describe why and how this occurs. Once animal-pollinated flowers evolved, a new type of plant–animal interaction was possible; describe it. How is it possible for a mutation in aplant to be beneficial for both the plant and for an animal?arrow_forwardDescribe the challenges for plants in terms of resource circulation or dispersal of reproductive structures from an evolutionary perspective (as they moved from single celled to colonial, to small and then large terrestrial forms. Describe the progression of structures from early evolutionary groups to later evolutionary groups to solve one of these challenges in 2-4 paragraphsarrow_forwardEXPERIMENT 4: INDUCTION OF CALLUS SOMATIC EMBRYOGENESIS OF HAPLOID PLANTS Objective: To prepare anther as a source of explant To induce callus somatic embryogenesis of haploid plants Procedure: Cut off the buds and sort them into 3 developmental stages based on length of buds Surface sterilize the buds in 70% ethanol for 2-3 minutes, making sure the entire bud is immersed in the alcohol. Drain off excess alcohol from the buds and aseptically excise the anthers from each bud. Remove the filaments and culture the anther on one of the agar media provided. Label the stage of development of the bud on each petri dish as the anthers are cultured. Seal the Petri dishes with parafilm. Incubate in the dark at 26 to 28ºC for 4 to 8 weeks or until small plants can be seen growing out of the anthers. Then transfer to diffuse light. Record the results of the experiment in table form and submit the report. Observation: The culture was contaminated after 8 weeks of incubation…arrow_forward
- Please answer question 1arrow_forwardWhen tomatoes are fully ripe, they develop bright red skins. William recently built a garden and decided to investigate tomato reproduction. He found that green tomatoes (not fully ripe) have an 18% chance of germinating while red tomatoes (fully ripe) have a 78% chance of germinating. Based on the data provided from the investigation, explain what characteristic(s) contributes to the probability of the tomatoes reproductive success and what factors (genetic or environmental) might impact the growth and development of the tomatoes. Answer should be based on : Claim: includes the idea that characteristic animal behaviors or specialized plant structures affect the probability of successful reproduction. Evidence: supports claim including: -behaviors and/or structures that increase the probability of reproduction -cause and effect relationship between the behavior/structure and the successful reproduction of organisms that have them -plant reproduction and the animal behaviors…arrow_forwardGiven below is an experimental setup to demonstrate a particular tropic movement in germinating seeds.
