AP BIOLOGY

Detailed explanation-1: -The procambium gives rise to vascular tissues, including the primary xylem and primary phloem. The ground meristem produces the cortex, a ground tissue. The protoderm produces the epidermis, a dermal tissue. The secondary meristems (lateral meristems) are the vascular cambium and cork cambium.

Detailed explanation-2: -The procambium is formed by smaller cells and longer than the ground meristem, gives rise to primary vascular tissue cells (primary xylem and primary phloem) and the pericycle.

Detailed explanation-3: -…as well as in the procambium; the procambium is the primary meristematic tissue between the primary phloem and xylem.

Detailed explanation-4: -The vascular tissues are renewed, and their extension is increased by the activity of the vascular cambium, which is the cause of the growth in thickness of the stems. The procambium remains in a meristematic state, after completing the primary growth (Plate 10.4A) and becomes the cambium.

Detailed explanation-5: -The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems. It is found in woody and many herbaceous dicots, gymnosperms and some monocots (monocots usually lack secondary growth).
