A geneticist crossed homozygous, dominant green pod color pea plants (GG) with homozygous recessive yellow pod color pea plants (gg). All the plants in the F1 generation had green pods. What ratio of green pod plants to yellow pod plants would you predict when you cross a green pod F1 plant with a yellow pod plant? A. All of the plants will have a green pod color. B. Half of the plants will have a green pod color, and half of the plants will have a yellow pod color. C. Three-quarters of the plants will have a green pod color and one quarter will have a yellow pod color. D. All of the plants will have a yellow pod color.

With the description of the different cell walls, membranes, and associated proteins set in the students' minds, you now need to introduce them to the idea that the cell wall can also act as a foundation to build things upon. bacterial appendages require a strong foundation that will offer the support needed to move and function in a dynamic world. for example, flagella are long, whiplike protein structures that are used by many gram-positive and gram-negative bacteria for locomotion. in order to function effectively, a flagellum must be firmly anchored to the cell wall. how will you be able to get across the idea that the peptidoglycan cell wall is strong enough to support such a mechanism? with a protein rod that passes through the cell wall and protein rings used to anchor it in the membranes, these basal bodies are the rudimentary biological motors that use atp power to spin the hook and the flagella attached to it. bacterial flagella have a biological motor that spins within the cell wall and is powered by atp. this allows the flagella to spin in a whiplike motion to propel the bacterium.
