- Many different treatments were possible in the phototropism experiment. Based on your understanding of phototropism, provide predictions about the direction of plant growth for the following two scenarios, and explain your reasoning. 1. The tip of the coleoptile is removed and lanolin with auxin is applied to the dark side of the stem. 2. The tip of the coleoptile is removed and lanolin with auxin is applied to the light side of the stem.arrow_forwardA) The concentration of CO2 is lower inside a plant cell than in the atmosphere (outside the cell). In your own words, describe how the CO2 levels are kept low inside the plant cell and explain why this is necessary. Assume stomata are open. B) Regarding the situation presented in Part A and assuming that the stomata of the plant leaves are closed, would this favour the induction of photorespiration in a C3 plant? Explain. Make reference to relevant molecule or molecules as needed. Please clearly label your responses as A and Barrow_forwardWatch the suggested videos for Plants Response to Stimuli. a.

- UntouhedLeaves Describe what happened to the Mimosa leaf when touched. The picture on top shows a screenshot of the reaction of the plant leaf to touch presenting rapid response or nastic movement. Choose the correct statement that describes your result.. a. The leaf would rapidly move to clump together. b. Leaves moves as if it is being moved by wind. c. The plant dies since its hyper sensitive to touch. d. Leaf would bend to look it has been wiltedarrow_forwardWhich of the following statements about gravity perception is FALSE? A. Statoliths are specialized amyloplasts B. Statoliths are found in statocytes C. Gravity is sensed from the root cap acropetally through the zone of division D. Columella cells sense gravity through statolith pressure on the endoplasmic reticulum E. Auxin is the main hormone involved in gravity responsearrow_forwardKindly provide 2 examples plants having "adaptations for twining" including (i) mechanical support (ii) transportation for root materials (iii) production of new plants Kindly sketch the diagramarrow_forward
- Determine the collective true-false status of the statements using the choices below. I. Xylem consists of cells called sieve elements and their associated companion cells.; II. Both sieve elements and the associated companion cells are alive in mature tissue.; III. Companion cells are a type of collenchyma.; IV. A companion cell provides each sieve element with metabolic support and transfers sugars into it. Only two (2) statements are true. None of the statements is true. All statements are true. Only one (1) statement is true. Only three (3) statements are true.arrow_forwardShow the sequence of secondary growth by drawing the row of cells from the boxed area below and labeling the vascular cambium cell (V), 5 xylem cells from oldest (X1) to youngest (X5), and 3 phloem cells (P1 to P3). Show what happens after growth continues by drawing and labeling a row with twice as many xylem and phloem cells. How does the vascular cambium’s location change? A pear has a hard texture but juicy. State two cells that give the characteristics? State the function of the transitional epithelium found in the mammalian urinogenital system.

(ii) Explain how the tissue named in (i) adapted to its function.arrow_forwardBelow are pictures of leaves from a Garry Oak tree (Quercus garryana).

ENCER 40x (x.s.) Describe two differences between sun and shade leaves at the macroscopic (leaf) and two differences at the microscopic (cross section) scale and provide explanations for the differences observed in color (specific chlorophyll a vs. b enrichment and accessory pigments) and shape (leaf thickness and width).

(c) Identify and describe a recent technology used to determine plant structure.arrow_forwardThe data that is attached below was collected during a lettuce seed ecotoxicity assay. Lettuce seed assays are used to compare the ecotoxicity of methanol, ethanol, and isopropanol by these alcohols' effects on germination rate and root elongination. Using the attached data, help answer which alcohol seems to be the most toxic to lettuce seeds. Why or why not would your results be expected? What does this information tell you about using ecotoxicity data to estimate human toxicity?arrow_forwardFigure 2 shows the cross-section of a eudicot root. i. Based on Figure 2, identify the structure that regulates the movement of water and minerals towards the xylem in the root. ii. Name structure of the cell membrane allows it to act as a selective barrier? iii. Predict what will happen to the transportation of water and minerals through the plasma membrane if the root was poisoned and no cellular respiration occurredarrow_forward
