- Apply Evolutionary Thinking A variety of structural features of land plants reflect the conflicting demands for conserving water and taking in carbon dioxide for photosynthesis. Identify at least four fundamental structural adaptations that help resolve this dilemma and explain how each one contributes to a land plants survival.arrow_forwardDiscuss Concepts Baobab trees (Adansonia spp.) store water in their trunks (stems) and, although the trees have leaves, considerable photosynthesis also occurs in the trunks. Cacti too have water-storing, photosynthetic stems. In terms of evolutionary adaptation, what does this information suggest about cacti and baobabs?arrow_forwardLab 13 (a)- Vascular Plant Reproduction Can you recognize if a cone is male or female? If provided actual flowers or images of flowers, can you determine if they are from a monocot or dicot plant (based on the expected patterns of petals) Can you identify key parts of a flower (sepals, petals, stamen, pistil, anther, filament, stigma, style, ovary, ovules) Difference between perfect & imperfect flowers? If a plant produces flowers, is it a gymnosperm or angiosperm? What are the names and functions of the 2 cells within a pollen grain? During double fertilization, what 2 structures are fertilized? What does each fertilized structure become?arrow_forward

- EXPERIMENT 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.
