Concept explainers
(a)
To evaluate:
An experiment was designed and conducted to analyze the uptake of sucrose in the plant cells. (a) The hypothesis for the decrease in pH, if plant cells are immersed in a sucrose solution. (b) The result obtained, if an inhibitor of the ATP regeneration was added in the beaker once the pH reached a steady level.
Introduction:
The plant cells were immersed in a sucrose solution in a beaker. The movement of the sucrose and water ions will take place by the process of diffusion and osmosis respectively in the beaker. The hypothesis given by the scientists proposes the movement of the hydrogen and sucrose ions inside the plant cells through the plasma membrane with the help of the co-transporter protein channels.
To evaluate: The hypothesis for the decrease in pH, if the plant cells are immersed in a sucrose solution.
(b)
To determine: The result that was obtained, if an inhibitor of ATP regeneration was added in the beaker once the pH reached a steady level.

- 1. Channel proteins used for the bulk passage of water molecules across the cell membrane?2. The tonicity of the extracellular fluid that maintains the turgid appearance of plant cells?3. The tonicity of the extracellular environment causing plasmolysis of plant cells?4. Plant cells are said to be flaccid in this type of cellular environment or solution?arrow_forwardConsider a cell membrane. In order to survive, the cell must move nutrients across the membrane and it must move waste products out of the membrane. Describe the strategies available to the cell for the transport of materials. Describe these strategies. Indicate what happens when equilibrium is reached for each strategy.arrow_forwardDesign an experiment to study the effect of solvent on the integrity of the membrahe of carrot-root cells. Remember that carrot contains carotenoids which include the yellow-orange colored pigments which can be collectively measured by a spectrophotometer at 450 nm. Also remember that these group are fat soluble. State your hypothesis, a brief summary of the experimental procedure and conditions, the expected outcome(s) and conclusion(s)arrow_forward
- 1.Base on your understanding of plant and animal cell osmosis, what condition do you think plant cells prefer? 2. What condition do you think animal cells prefer? Consider the question: How is solute concentration related to the change in the weight of plant cells (like potato cells)? 5. Write a hypothesis from the above question. Write one if statement and make three predictions(then statements) regarding how the cell will change (weight) in (1) hypertonic,(2) hypotonic, and (3) isotonic conditions:arrow_forwardBelow are three statements - two of which are truths and one is a lie. Which of the following statements is a lie? Select one: a. Plant cells never shrink with the support of cell wall. b. Low osmolarity means high water content. c. Saltwater fish secrete salt through their gills and have concentrated urine.arrow_forwardHow does the presence of high concentrations of salt orsugars in food prevent growth of microorganisms?(a) It sets up a hypotonic environment causing the cells tolyse.(b) It sets up an isotonic environment in which cells die.(c) It sets up an environmental high in osmotic pressureresulting in cellular plasmolysis (water loss).(d) a and b.(e) None of the above.arrow_forward
- (2) a. Mineral salt is essential for growth of a plant. The process responsible for absorption of mineral salt is: a. Mass flow b. Diffusion Active transport C. d. Osmosis b. The reason for my answer is because : a. Absorption occurs due to concentration gradient b. Absorption occurs with the help of energy opposing to diffusion C. Movement as a bulk due to pressure changes d. Absorption through permeable membranesarrow_forwardEXPERIMENT : CRYOPRESERVATION OF CULTURED CELL LINES Questions What are differences between adherent and suspension cells. After 3 days of cryopreservation, the cell morphology was observed under the microscope.The total cell concentration is reduced into half of the number after cryopreservation. What are reasons for decreasing in cell concentration.Justify your answer.arrow_forwardAs bacteria grow, they produce acidic metabolic waste products that gradually slow down the rate of cell division. Based on this, which buffer would you expect to allow the bacteria to grow for a longer period of time before slowing down? Include the reasons supporting your prediction.arrow_forward
- Why should it not be surprising that for many cells water requires a protein for its transport across a membrane? A. There is never a concentration gradient for water across the membrane to drive its transport. B. The transport protein is needed to prevent the hydrolysis of the phospholipid chains as water crosses the membrane. C. Water is very polar which inhibits its free diffusion across the membrane. D. All molecules require transport proteins to cross a membrane. In the mitochondria phosphate ion (PO43-) and H+ are transported together from the intermembrane space into the matrix. Which statement applies? A. The interior of the transport protein must be uncharged. B. The transport protein must have a relatively large central channel to accommodate both ions. C. The transport protein is a symport. D. All of the abovearrow_forwardExamine the plant cell shown below, and answer the following questions about it. A.
