Questions 3—5 are worth 4 points each and questions 6—8 are worth 3 points each. Questions 3—8 are short free-response questions that require about 6 minutes each to answer.

It turned out later that other hormones see ethylene, below are mainly responsible for abscission, but the name stuck.

Plant hormones ap biology questions

Produced in roots and transported throughout plant. When stem is unequally stimulated by light, auxin moves to shady region for elongation. Questions 3—5 are worth 4 points each and questions 6—8 are worth 3 points each. Part of our Plant Biology Learning Guide. Include in your discussion a sample cross es sufficient to verify your proposed pattern. The arrows indicate reaction sites for two restriction enzymes enzyme X and enzyme Y. This trait is determined by a single autosomal gene and is expressed as two phenotypes. Promotion of fruit development, seed germination, and inhibition of aging leaves. McCormick's Test on Plant Hormones. Include in your answer a discussion of how the different types of RNA function in this process. When all sides equally stimulated by light, growth is straight. Describe a procedure by which this can be done. Cytokinins do a couple other things too: Genetic variation is the raw material for evolution. Variations structurally of nitrogenous base adenine.

Hypothesis: cells on the darker side of the coleoptile elongate faster than those on the lighted side. Interact with auxins to stimulate shoot growth.

Occurs in young leaves, roots, and seeds. Growth of lateral buds weakening apical dominance Found to delay senescence aging of leaves. Describe the modern theory of evolution and discuss how it is supported by evidence from two of the following areas. Describe each classical experiment and indicate how it provided evidence for the chemical nature of the gene. Begin with the separation of the messenger RNA from the DNA template and end with the release of the protein at the plasma membrane. Include in your discussion a sample cross es sufficient to verify your proposed pattern. Promotion of fruit development, seed germination, and inhibition of aging leaves. Effects depend on target tissue and also presence of auxin. However, cytokinins need auxin to induce cell division. Describe the most probable pattern of inheritance for this condition. Describe a procedure by which this can be done. Interact with auxins to stimulate shoot growth. Produced at tips of shoots and roots and also influences plant responses to light phototropism and gravity geotropism , Active in leaves, fruits, and germinating seeds.

After four generations, the following results were obtained. The arrows indicate reaction sites for two restriction enzymes enzyme X and enzyme Y.

This causes the coleoptile to bend toward light. Explain how these alleles are transmitted by the process of mitosis to daughter cells. However, not everyone knows that similar regulators-hormones — are also in plants. If the homozygous dominant condition were to become lethal, what would happen to the allelic and genotypic frequencies in the rabbit population after two generations?
