2 lut 2023 · A typical plant stem consists of eight distinct parts, containing six elements and two organs. The six elements are: 1) nodes , 2) internodes , 3) terminal or apical bud , 4) lateral or axillary bud , 5) petiole and 6) pedicel.
28 sie 2024 · The stem and other plant organs are primarily made from three simple cell types: parenchyma, collenchyma, and sclerenchyma cells. Parenchyma cells are the most common plant cells. They are found in the stem, the root, the inside of the leaf, and the pulp of the fruit.
18 maj 2024 · Development of stem starts from stem apical meristem (SAM) on the top of plant. The SAM produces three primary meristems: procambium, protoderm, and ground meristem. Protoderm cells differentiate into epidermal cells. The ground meristem differentiates into the cortex external layer of primary stem or root and pith central layer of primary stem ...
2 dni temu · In this explainer, we will learn how to describe the basic structure of a plant stem and recall the functions of different parts of the stem. Plant stems are vital to their survival. Stems are long, stalk-like structures that form the main body of a plant.
Stems are produced by the primary apical meristem in but may be increased in girth in woody plants due to secondary growth. Secondary growth is produced by lateral meristems in the woody stems and roots of woody plants. Secondary xylem and secondary phloem are produced from a cylinder of meristematic tissue within the woody stems and roots.
External Structure of the Stem of a Typical Dicotyledonous Plant . Stem Function: a. Support of main body of plant & leaves. b. Conduct water & food. c. Photosynthesis in new green stems.
