Question
Chapter 19, Problem 2WIO
Summary Introduction
To analyze:
The alternation of generations common to all plants. Is there any variation among the gametes, if DNA of all the gametes produced by one gametophyte is analyzed?
Concept Introduction:
The alternation of generation includes the haploid and diploid gametes formation by mitotic division by the gametophyte. The DNA describes ploidy of the cells.

- What is the evolutionary trend in the alternation of generation in plants?arrow_forwardThe leafy, green moss plants that are familiar are gametophytes, haploid plants. This is very different from flowering plants and other seed plants. Does a leafy green moss plant grow from a spore or from a fertilized egg? Does the moss plant have both paternal parent and maternal parent?arrow_forwardWhat is the evolutionary trend in the alternation of generation in plants?

- Bolting is when a plant starts to spend its energy on producing flowers. Initial bolting time is figured by the number of days from germination to bolting. Rosette area is figured by the average rosette area of the plant at the time of bolting. Researchers created strains of A. thaliana to have varying somatic ploidy levels to study the resulting phenotypes. The graphs show how initial bolting time and rosette area relate to the number of chromosomes in each strain’s somatic cells. Which of the following best describes how a change in genotype affects the phenotype of A. thaliana? The largest average change in both phenotypes occurred from the 2n to the 4n strain. The largest average change in both phenotypes occurred from the 4n to the 6n strain. A lesser number of chromosomes results in plants with a later initial bolting time. A greater number of chromosomes results in plants that have larger rosettes areas.arrow_forwardWhich of the following pairs of plant structure has the haploid number ofchromosomes? A. Megaspore mother cell and antipodal cells B. Egg cell and antipodal cells C. Egg cell and endosperms D. Microspore mother cell and antipodal cellsarrow_forwardCompare and contrast the alternation of generations in pines and angiosperms. This must be very detailed and include all major structures and process involves. Be sure to include when the plants are haploid or diploid. You can use a list as long as order is clear. Be sure to clearly write out structure and processes and indicate which things are the same and which are different.arrow_forward
