ARoots have lots of cortex and little pith
BRoots have lots of pith and little cortex
CRoots have neither cortex nor any pith
DRoots have equal cortex and pith amounts
Answer & Solution
Correct answer: A. Roots have lots of cortex and little pith
1. Inside the root the ground tissue forms two regions, the cortex and the pith.
2. Compared with stems, roots have lots of cortex and little pith.
3. Both regions include cells that store photosynthetic products.
4. Reversing the proportions describes the stem rather than the root, which is the trap in the second option.
