Summary Introduction

To determine:

The path of water and dissolved minerals from the soil, into the root’s xylem, and up to leaves.

Concept introduction:

When water transport occurs through cytoplasm and vacuoles of the cell; the route which water have opted is termed as a symplastic pathway, whereas, when the water moves only through the xylem; the route of water transport is termed as an apoplastic pathway. Casparian strips which made up of an impermeable substance play a key role for water in switching to symplastic pathway from the apoplastic pathway.

You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb?  Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.
Design a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.
The Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why?   Question 21 options:   orange because A is epistatic to B   yellow because A is epistatic to B   red because B is epistatic to A   orange because B is epistatic to A   red because A is epistatic to B   yellow because B is epistatic to A
