Chapter 37, Problem 7TYK
Summary Introduction
Introduction:
Flowering in plants is a process affected by photoperiodism. These photoperiodic responses presented by the plants are predictable and help in categorizing plants into two major categories. These are long-day plants, which flower during the season when days are longer than nights, and short-day plants, which flower in a season when nights are longer.

- Under which of the following conditions would pollen from an S2S5 plant successfully pollinate an S1S5 flower? a. Using pollen from a carpelate flower to fertilize a staminate flower would be successful. b. If the plants used gametophytic self-incompatibility, half of the pollen would be successful. c. If the plants used sporophytic self-incompatibility, half of the pollen would be successful. d. Pollen from an S2S5 plant can never pollinate an S1S5 flower.arrow_forwardPlease answer question 13arrow_forwardPlease answer question 16arrow_forward
- Can you clearly type the answers to the all the parts to this question please a) What is the role of the LEAFY gene in floral development? (b) What is the phenotype of the leafy mutant? (c) Most of the ABC program genes are directly regulated by the transcription factor LEAFY (LFY). Still, LFY is expressed broadly throughout the floral meristem when the discrete A, B, and C domains are established. Discuss how this single broadly expressed transcription factor can generate distinct domains of ABC gene expression.

- Plants and animals usually battle each other; describe why and how this occurs. Once animal-pollinated flowers evolved, a new type of plant–animal interaction was possible; describe it. How is it possible for a mutation in aplant to be beneficial for both the plant and for an animal?arrow_forwardPlease answer question 2arrow_forwardHow can synthetic promoters alter plants system? A. Introduction of a heterologous DNA into plants directly manipulates the regulatory elements or expression of endogenous genes. B. Development of a phytosensor combined with signal transduction pathway activates signal to detect pathogens. C. Utilization of an engineered DNA - binding domains and catalytic effector results to modified signal responses.arrow_forward
- The ABCDE Model of flower development dictates the combination of transcription factors require to initiate each whorl of a flower. Based on the diagram below, what would happen if: Carpels and ovules Sepal Petal Stamen 2 4 Whorl A Genes E 25-40 The ABCDE model of floral organ determination in Arabidopsis In addition to the A-, B-, and C-function genes of the ABC model, this model includes two additional gene classes, D and E. In the ABCDE model, class A + E genes specify sepals; class A + B + E, petals; class B +C +E, stamens; class C + E, carpels; and class C+ D + E, ovules. 1. Gene D was non-functional: 2. Gene E was non-functional: 3. Only Gene A was functional: 4. Gene B and E were non-functional: 5. Only Gene A and Gene E were functional: Hint: If Gene A was non-functional the flower would have no sepals or petals, it would be composed of only stamens and carpels.arrow_forwardThe image below represents a flower meristem viewed from above. At the time the image represents, the cells are undifferentiated, although their eventual fates are determined (e.g. carpels, etc.). The rectangles indicate the regions of the meristem where particular genes (A, B, and C) are expressed. Note that these genes are expressed all around the circumference of the meristem at the location indicated; in other words, gene A is active in all cells in the rings labeled sepal and petals. Interpret the figure by filling in the following table: I've numbered each row to help with writing the answer below. Determined by the activity of which gene(s) - A,B,C? Organ Carpel 1. Stamen 2.
