Cells in the tunica layers of the SAM undergo anticlinal divisions only (b)periclinal divisions only c. both anticlinal and periclinal divisions 13. Which of the following tissues in NOT produced by the corpus region of a. epidermis b. cortexExplanation / Answer
8.
Option E is correct.
All the mentioned cell wall components are transported by vesicular transport from the cis Golgi.
9.
Option D is correct.
Tryptophan is the biosynthetic precursor for auxin synthesis.
10.
Option B is correct.
vir genes are removed from Agrobacterium so that the bacteria become avirulent but can still infect and integrate t-DNA into the plant genome.
11.
Option E is correct.
The basal produced by the first zygotic division develops into a suspensor which serves as a haustorium to provide nutrition to the growing apical cell.
12.
Option B is correct.
Tunica is the outermost monolayer that divides only in the anticlinal fashion to produce epidermis.
13.
Option A is correct.
The epidermis is not produced by corpus region of the meristem.
