Question
Chapter 28, Problem 16TYU
Summary Introduction

To explain: The way in which bisexual flowers are an advantageous evolutionary adaptation to the plants that produce them.

Introduction: Plants may have unisexual flowers or bisexual flowers. Bisexual flowers such as lily and rose have both male and female organs in the same flower. Bisexual flowers are most common in flowering plants. In gymnosperms, cones are either male or female. The presence of bisexual flowers provides an evolutionary advantage to angiosperms compared to the unisexual cones of gymnosperms.

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.  Observation:  The culture was contaminated after 8 weeks of incubation…
