Which of the Following Statements Describes the Hypothesis Proposed to Explain

question 81

Multiple Choice

Which of the following statements describes the hypothesis proposed to explain the regular arrangement of leaves around the stem?

• A)Primordia are genetically preprogrammed to grow in a regular pattern.
• B)Primordia secrete growth inhibitors that block new primordia from forming near them; where these signals are at a minimum, farthest from existing primordia, a new primordia can form.
• C)New primordia initiate where auxin accumulates, while existing primordia efficiently drain auxin from the meristem surface. This ensures that new primordia form in the location farthest from existing primordia.
• D)Developing leaf primordia physically block new primordia near them, such that new primordia initiate in the largest space not currently occupied by existing primordia.
• E)We do not currently have a hypothesis to explain this growth pattern.
