Difference between Root and Stem Anatomy | EasyBiologyClass
Stem: Stem is the part of the plant which lies above the surface of the soil. It arises from the plumule of the embryo. Stem shows positively phototropic and negatively geotropic growth. Stem possess nodes and internodes. Branches, leaf, flower bud and bracts are developed from nodes.

Chapter 8: Vascular plant anatomy: primary growth
The three organs differ in the distribution of vascular tissue: in roots it occurs as a single central strand; in stems, the vascular tissue occurs as multiple bundles imbedded in ground tissue; and in leaves the vascular tissue often occurs as a reticulate network …
Transverse Sections: Stems, Roots & Leaves | OCR A Level Biology ...
2022年6月2日 · Plants have a vascular system which involves a network of vessels (vascular tissue) running through the leaves, stem and roots. These three parts are the main organs involved in transport. Tissue plan diagrams of a dicotyledonous leaf, stem and root.
Difference Between Root and Stem - Biology Reader
Stems bend towards the light and are positively phototropic, while roots are negatively phototropic. Roots are the tubular structures that move towards the water and show positive hydrotropism, whereas stems are the branched structures that move away from the water and are negatively hydrotropic.
5.2 Inside Stems – The Science of Plants - Open Textbook Library
Discuss how stems grow by elongation and by increasing their girth or diameter. Identify the tissues that are initially produced by apical meristems and the cells into which they eventually mature. Distinguish monocot and dicot stems based on the arrangement of the vascular bundles.
Difference Between Stems and Roots (with Comparison Chart)
2019年3月1日 · Stems possess nodes and internodes, but roots do not have. Stem branches are superficial or exogenous and develop from axillary buds; on the other hand, root branches are deep-seated or endogenous, though root branches do not arise from any specific area.
Stem vs. Root: Key Differences in Plant Structure and Function
2024年11月30日 · While stems and roots are both essential parts of plants, they have distinct roles and characteristics that set them apart. Stems are known for their vascular tissues that transport materials, while roots focus on anchoring and absorption. Additionally, stems tend to grow upwards, while roots grow downwards, following gravity’s lead.
Internal Structure of Stem (With Diagram) - Biology Discussion
In fact, three important organs of a plant are the stem, the leaves and the root. The continuity of the tissues, and particularly the vascular system, has been discussed in the preceding chapter. Apical meristems occurring at the tips of the axis, the …
