Root Charts, Botany, School Education

Quick Answer: Root Charts are botany wall charts illustrating the types of root system, the zones of a growing root tip, root modifications such as storage and prop roots, and the internal structure of dicot and monocot roots. They support school and college lessons on absorption and anchorage.

Roots Below and Above the Soil

The first distinction on root charts is between a taproot system, with one main root and its branches, typical of dicots such as mustard and gram, and a fibrous root system of many similar thin roots, typical of monocots such as wheat and grasses. A root-tip diagram then shows the root cap protecting the tip, the region of cell division, the region of elongation and the region of maturation with its root hairs, which provide a large surface for absorbing water and minerals.

Modification sheets are usually the most colourful: carrot, radish and turnip swollen as storage taproots, sweet potato as a tuberous root, the hanging prop roots of the banyan, the stilt roots of maize and sugarcane, and the upward-growing breathing roots (pneumatophores) of mangroves such as Rhizophora in swampy soil. Sectional diagrams contrast the dicot root, with a few xylem bundles, with the monocot root, which has many.

Care & Handling

• Keep the root charts out of the germination corner, where damp cotton and seed trays raise the humidity around the paper.
• Put the modification sheet up for the vegetable-sorting activity and take it down afterwards so it stays clean.
• Store the root sheets with the stem sheets, because students often confuse modified roots and underground stems and need both to compare.

Applications

• Growing seedlings on moist blotting paper to observe root hairs
• Sorting vegetables into roots and stems in a market-survey activity
• Teaching absorption and osmosis through root hairs
• Section cutting of roots in senior secondary and college practicals

Why Choose LabEquip

Botany teachers commonly buy root charts with the Stem Charts, since students must learn to tell modified roots from underground stems, and use root-tip slides from the prepared slides range. Orders go through the LabEquip contact page.

Frequently Asked Questions

What is the difference between a taproot and a fibrous root system?

A taproot system has one thick primary root growing straight down with smaller lateral roots, as in dicots such as mustard. A fibrous root system has many thin roots of similar size arising from the base of the stem, as in monocots such as wheat.

What do root hairs do?

They are thin outgrowths of single epidermal cells in the zone of maturation. They greatly increase the surface area for absorbing water and dissolved minerals and help the root grip soil particles.

Is a potato a root?

No. A potato is a stem tuber: its eyes are buds that grow into new shoots. Sweet potato, carrot and radish are true roots modified to store food.

What are prop roots and stilt roots?

Both are roots that grow from the stem above ground to give extra support. Prop roots hang from the branches of the banyan tree and thicken into pillars, while stilt roots grow from the lower nodes of maize and sugarcane into the soil.

Why do mangroves have breathing roots?

Mangrove mud is waterlogged and short of oxygen. Pneumatophores grow upwards out of the mud and have pores through which air reaches the roots below.

What does the root cap do?

It is a thimble-shaped layer of cells covering the root tip, protecting the dividing cells behind it as the root pushes through soil. Its outer cells wear away and are continually replaced.
