Feb 3, 2023 · It is the root system that develops from the growing embryo (radicle) of a germinating seed. The taproot is the true root that grows vertically downwards and produces many lateral roots called root hairs. The taproot system is present in all dicot plants. Examples: Mango, carrot, radish, sugar beet, and parsnip. 2. Adventitious Root System
germination: the beginning of vegetation or growth from a seed or spore. This page titled 30.6: Roots - Types of Root Systems and Zones of Growth is shared under a CC BY-SA 4.0 license and was authored, remixed, and/or curated by Boundless. The root tip has three main zones: a zone of cell division, a zone of elongation, and a zone of maturation.
Root hairs, which are extensions of root epidermal cells, increase the surface area of the root, greatly contributing to the absorption of water and minerals. Inside the root, the ground tissue forms two regions: the cortex and the pith (Figure 30.3.3 30.3. 3). Compared to stems, roots have lots of cortex and little pith.
Roots. Plants have specialized organs that help them survive and reproduce in a great diversity of habitats. Major organs of most plants include roots, stems, and leaves. Roots are important organs in all vascular plants. Most vascular plants have two types of roots: primary roots that grow downward and secondary roots that branch out to the side.

A plant’s root system can be either fibrous or have a distinct tap root. Many dicot plants have a main root known as the tap root which has many lateral roots growing from it. By having a thick tap root that grows deep into the soil, the plant gains extra anchorage to the ground. Some plants species have extra thick tap roots such as carrots and pa...
Plant roots are important for securing the plant to the soil but the majority of nutrient uptake occurs near the tip of the root. Here a large number of root hairs grow; very fine roots with large surface area to volume ratio. By having a large surface area and low volume it increases the efficiency of absorption of minerals and water.
A common feature of almost all root systems is what is known as mycorrhizae. A mycorrhizae is a relationship between the roots of a plant and fungi where both species usually benefit. The plant supplies the fungi with a constant source of sugars and the superior absorption abilities of the fungi help to provide the plant with an increased supply of...
It is common knowledge that roots grow below ground, but in certain cases, plants will grow roots above ground from stems and even leaves. Plant roots such as these are labelled adventitious, a term used to describe a structure that grows in a strange place. The banyan tree is a great example of a species with adventitious roots, which have a large...
Root systems are mainly of two types (Figure 30.15). Dicots have a tap root system, while monocots have a fibrous root system. A tap root system has a main root that grows down vertically, and from which many smaller lateral roots arise. Dandelions are a good example; their tap roots usually break off when trying to pull these weeds, and they ...
