What specialized types of primary meristems develop from a shoot apical meristem?
A) epidermis, pith, cortex
B) protoderm, ground meristem, procambium
C) primary xylem, primary phloem, cortex
D) secondary xylem, secondary phloem, pith
E) vascular cambium, ground meristem, pith

Question

Quizplus · Accepted Answer

The specialized types of primary meristems that develop from a shoot apical meristem are protoderm (for the epidermis), ground meristem (for the cortex and pith), and procambium (for the primary xylem and phloem). Therefore, choice B is correct. Choice A is incorrect because pith and cortex are derived from the ground meristem, not primary meristems. Choice C is incorrect because primary xylem and phloem are derived from procambium, not cortex. Choice D is incorrect because secondary xylem and phloem are derived from a lateral meristem (vascular cambium) and not primary meristems. Choice E is incorrect because the vascular cambium also develops laterally, not from a shoot apical meristem.
