AP BIOLOGY

Detailed explanation-1: -apical meristem, region of cells capable of division and growth in the root and shoot tips in plants. Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots.

Detailed explanation-2: -Apical meristems are found at the apex, or tip, of roots and buds, allowing roots and stems to grow in length and leaves and flowers to differentiate.

Detailed explanation-3: -The root apical meristem produces the three primary meristems: procambium, ground meristem, and protoderm. 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.

Detailed explanation-4: -Primary growth occurs at the apical meristem (a meristem located at the tip of a stem). A meristem is a region of undifferentiated cells from which new cells arise through cellular division.
