Differences Between Rhizome and Tuber

This concludes some important differences between rhizomes and bulbs.

Differences between rhizome and tuber and stem tuber

What is Tuber?

The cortex is the fleshy part of a plant that stores food. Potatoes are the most commonly used food. The lower part of the pod is covered with soil by adventitious branches. The bulb is covered with a series of depressions called “eyes”, each eye representing a disease.

What is Rhizome?

The rhizome is a long underground root with a green, fleshy collar, separate from the central nodes. They are artificial brown just like the apical buds. They have terminal shoots and run parallel to the ground

Common rhizome species are alocasia indica, ginger and banana. Leaves are also called roots, which tend to grow vertically in the direction of gravity, ie. horizontally The rhizome grows vertically higher than horizontally.

Differences Between Rhizome and Tuber

Rhizome

Tuber

Roots

Grows horizontally inside the soil

Has fleshy roots

Stem

Rhizomes are thickened underground stems.

Tubers are modified stems with starchy interiors

Nodes

Nodes bear adventitious roots

Nodes do not bear roots

Growth Habit

Rhizomes grow horizontally.

Tubers do not have a well-organized growing habit.

Shape and structure

Rhizomes are pear-shaped.

Tubers do not have a standard shape.

Size

Smaller in size compared to tubers

Larger in size than rhizomes.

Types of Rhizomes and Tuber

Most of the structure is not found in the leaves.

There are two types of tubers-stem and root tubers.

  • Rhizomes produce offspring.
  • Tubers grow in size every year.

Examples

  • Asparagus, Bamboo, ginger, Lotus, the Venus Flytrap, turmeric, etc.
  • Begonia, cassava, Dahlia,¬†Oxalis, potato, sweet potatoes.
