Remove the leaves from the bottom nodes leaving a bare stem not terminating with a node. Dip the part of the stem below the leaves of one shoot into water, and then into a dry compound of Indole-3-butyric acid. Insert the cut stump into one of the cups provided, and fill with water saturated peat moss.
Root Growth and Anatomy. Root growth begins with seed germination. When the plant embryo emerges from the seed, the radicle of the embryo forms the root system. The tip of the root is protected by the root cap, a structure exclusive to roots and unlike any other plant structure. The root cap is continuously replaced because it gets damaged ...
In the xylem and phloem, you can find sclerenchyma with secondary walls. In the epidermis, you can see elongated cells called root hairs projecting outward. This region is called the zone of maturation. Figure 7.3.3 7.3. 3: Zone of maturation. Locate each of the zones described above and draw a root tip below.
3.3 Roots. Though unseen, the roots of a plant also have specialist anatomical features that enable plants to efficiently obtain nutrients and control the substances entering a plant. Figure 3.9. Diagram of the structures of and areas of a developing root. (Image from: Marsland, Douglas. (1964) Principles of modern biology.
Feb 17, 2023 · A typical plant root system shows four distinct regions or zones: 1) region of root cap, 2) region of cell division or meristematic region 3) region of elongation, and 4) region of maturation or differentiation. Each region of the root performs specific functions. Except for the root cap, the other three zones are collectively known as the ...

Definition of Root System. The root system refers to the ramose structures that exist subterranean or superterranean to the earth surface. A root consists of the hard root cap, primary root meristem and root hairs. The growth of the root system depends upon the soil composition, soil type, type of plant species and growth conditions.
