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.
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 ...
28 sie 2024 · Stem Anatomy. 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.
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.
3 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.
1. Epidermis - the exchange of matter between the plant and the environment. The epidermis on aboveground organs (leaves and stems) is involved with gas exchange. The epidermis on belowground organs (roots) is involved with water and ion uptake. 2. Vascular tissues - the transport of water and dissolved substances inside the plant.
