The primary growth of a stem

Webb21 jan. 2024 · Primary growth occurs in areas called apical meristems. This type of growth allows plants to increase in length and to extend roots deeper into the soil. All plants undergo primary growth. Plants that undergo secondary growth, such as trees, have lateral meristems that produce new cells. These new cells increase the thickness of stems and …

Plant Development II: Primary and Secondary Growth

WebbAs the stem continues to grow, lateral buds are produced that develop into lateral shoots more or less resembling the parent stem, and these ultimately determine the branching of the plant. In trees the lateral shoots develop into branches, from which other lateral shoots, called branchlets, or twigs, arise. WebbPrimary Root Tissues and Structure The organization of tissues in the primary root is simpler than in the primary stem because no leaves are produced on the roots and, consequently, there is no need to connect the vascular system laterally to offshoo … View the full answer Previous question Next question ima stick with you forever https://peruchcidadania.com
