In the symplast pathway, water passes from one root cell to the next through fine cytoplasmic connections. These connections are called what?
ASieve plates
BStomata
CHydathodes
DPlasmodesmata
Answer & Solution
Correct answer: D. Plasmodesmata
1. The symplast route runs through cytoplasm of adjacent cells.
2. Sieve plates belong to phloem sieve tubes, so option A is wrong.
3. Hydathodes and stomata are pores for water release, not cell-to-cell links, ruling out options B and C.
4. The cytoplasmic bridges between cells are plasmodesmata, option D.
