Auxin b. Cytokinin c. Ethylene d. Gibberellin Your answer is correct. The correct answer is: Auxin Question 2 Partially correct Mark 1.00 out of 2.00 From the Short (open in another tab), below, which is the plant hormone that is responsible of "producing rich juice grapes"? Grape Farming a. Ethylene b. Auxin c. Cytokinin d. Gibberellin Your answer is partially correct. You have correctly selected 1. The correct answers are: Auxin, Gibberellin Question 3 Correct Mark 2.00 out of 2.00 What type of tropism is being shown by the structure within the 'red diagram', in the picture below?  a. Gravitropism b. Geotropism c. Positive geotropism d. Negative phototropism Your answer is correct. The correct answers are: Positive geotropism, Negative phototropism Question 4 Incorrect Mark 0.00 out of 2.00 The picture, below, shows in the plant of coleus, high auxin concentration develop axillary bud and low auxin concentration inhibit axillary buds. Select one: True False  The correct answer is 'False'. Question 5 Complete Mark 1.00 out of 6.00 Explain what happens in the bending of the epidermal tissue in the shoot apical meristem. Auxin causes cell elongation in the shoot apical meristem. In phototropism, experimented b Darwin and Boysen-Jensen, light causes auxin to accumulate on the shaded side of the shoot. distribution then leads to more excellent elongation of cells on the shaded side of the sho to bend towards the light.  Comment: The specific process is needed to be described. Question 6 Correct Mark 2.00 out of 2.00 In phototropism, the shoot apical meristem do the bending due to the process of cell elongation that occurs in the the ground tissue layer. True False The correct answer is 'False'. Question 7 Correct Mark 2.00 out of 2.00 Which plant hormone is responsible for the fruit ready to do a pastry, as the picture below shows?  a. Gibberellin b. Abscisic Acid c. Ethylene d. Auxin Your answer is correct. The correct answer is: Ethylene Question 8 Correct Mark 2.00 out of 2.00 What conclusion can be gotten from the picture below? a. Lack of di"erentiation when both are present b. Cytokinin promotes root formation, Auxin promotes shoot formation c. Auxin promotes root formation, Cytokinin promotes shoot formation d. None of these Your answer is correct. The correct answer is: Auxin promotes root formation, Cytokinin promotes shoot formation Question 9 Incorrect Mark 0.00 out of 2.00 What type of tropism is being shown by the structure within the 'red diagram', in the picture below? a. Hydrotropism b. Phototropism c. Negative phototropism d. Positive geotropism Your answer is incorrect. The correct answer is: Positive geotropism Question 10 Correct Mark 2.00 out of 2.00 Gibberellin promotes fruit ripening Select one: True False The correct answer is 'False'. Question 11 Partially correct Mark 8.00 out of 10.00 Pictionary and Definitions~~~ Carefully read the questions and answer properly. ____________________ is the response to change in length of the night, that results in flowering in long-day and short-day plants. Photoperiodism It is the natural or artificially induced production of fruit without fertilization of ovules, which Parthenocrpy makes seedless fruit. What is the name of the tropism in the video below? Thigmotropism In a plant's life cycle, the deteriorative process which naturally terminates the functional life of Senescence an organ, organism or other life unit. What process does the picture,below, demonstrate? Photoperiodism Your answer is partially correct. You have correctly selected 4. The correct answer is: ____________________ is the response to change in length of the night, that results in flowering in long-day and short-day plants. → Photoperiodism, It is the natural or artificially induced production of fruit without fertilization of ovules, which makes seedless fruit. → Parthenocrpy, What is the name of the tropism in the video below? → Thigmotropism, In a plant's life cycle, the deteriorative process which naturally terminates the functional life of an organ, organism or other life unit. → Senescence, What process does the picture,below, demonstrate?  → Photomorphogenesis Question 12 Correct Mark 2.00 out of 2.00 Cytokinins promote cell division. True False The correct answer is 'True'. Question 13 Correct Mark 2.00 out of 2.00 What is the name of the multicellular swelling located in the base of each leaf or leaflet, as shown below? a.
