Worked Solution & Example Answer:Which alternative correctly describes the process involved in the movement of materials in the cells labelled M and W? A typical vascular bundle from a stem Mauseth, James D, 1988, Plant Anatomy, Benjamin/Cummings Pub - HSC - SSCE Biology - Question 13 - 2003 - Paper 1
Step 1
M: Active transport
Answer
Active transport is the process that occurs against the concentration gradient, requiring energy input, usually in the form of ATP. In this case, the movement of materials in cell M indicates an active role in transporting substances such as nutrients, ions, or hormones, which is essential for maintaining necessary cell functions.
Step 2
W: Active transport
Answer
Similarly, the movement in cell W also involves active transport. This is necessary to ensure that specific substances can be absorbed even when they are present in lower concentrations outside the cell, highlighting the role of cellular mechanisms that help maintain homeostasis and nutrient uptake.
