WebThe cells have no intercellular space. The zone where these cells exist is known as meristem. The cells of the meristematic tissue divide actively to form specialized structures such as buds of leaves and flowers, tips of roots and shoots, etc. These cells help to increase the length and girth of the plant.

Often, the apical meristem of a single branch will become dominant, suppressing the growth of meristems on other branches and leading to the development of a single trunk. orica training

Root Meristems - an overview ScienceDirect Topics

WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ... WebThe growing root tip is protected by a root cap. The root tip has three main zones: a zone of cell division (cells are actively dividing), a zone of elongation (cells increase in length), and a zone of maturation (cells differentiate to form different kinds of cells). Root vascular tissue conducts water, minerals, and sugars.

WebJun 1, 2024 · The cells present here are meristematic in nature and are thus small, thin-walled with dense protoplasm. It occupies a small fraction of the root length, and the cells here divide continuously to add new cells to the root cap and the zone of elongation. Thus it is responsible for the increase in the length of the root.
