Primary meristem
Apical meristems may differentiate into three kinds of primary meristem: • Protoderm: lies around the outside of the stem and develops into the epidermis. • Procambium: lies just inside of the protoderm and develops into primary xylem and primary phloem. It also produces the vascular cambium, and cork cambium, secondary meristems. The cork cambium further differentiates into the phelloderm (to the inside) and the phellem, or cork (to the outside)… WebPrimary growth adds length or height, mediated by apical meristem tissue at the tips of roots and shoots—which is difficult to show clearly in cross-sectional diagrams. Secondary growth adds to the diameter of a stem or root; vascular cambium adds xylem (inward) and phloem (outward), and cork cambium replaces epidermis with bark.

WebFeb 18, 2024 · Explanation: Primary occurs in roots of both dicots (plants bearing dicotyledonous seeds) and monocots (plants bearing monocotyledonous seeds). Primary growth occurs due to the activity of root apical meristem, a primary meristem. Primary growth involves elongation in length. Secondary growth involves increase in the girth or …
WebThese three types of meristem are considered primary meristem because they allow growth in length or height, which is known as primary growth. Secondary meristems allow growth in diameter (secondary growth) in woody plants. Herbaceous plants do not have secondary growth. The two types of secondary meristem are both named cambium, meaning ... WebCause secondary growth of the plant. 5. Formed when the plant starts its growth.

WebPlants experience a vast array of conditions that can alter their growth and development, including temperature and availability of water, nutrients, and light. They are also exposed to pollutants such as acid rain formed largely as a result of burning fossil fuels and volcanic eruptions.
