What is the difference between rhizome and tuber?

The rhizomes are strips, and the tubers are lumpy, think sweet potatoes.

A rhizome is an umbrella term (a stem that grows like a root in the ground).

Rhizomes include rhizomes, tubers, bulbs, and bulbs;

1.rhizomes: the most common, with different shapes, cylindrical, spindle-shaped, or irregular blocks, such as Atractylodes, Atractylodes, etc.; Turnips are rhizomes;

2.Tuber: irregular tuber or spherical, fleshy hypertrophy, short internodes on the surface, toothy and vestigial scaly leaves on the nodes or have fallen off, such as Banxia, Gastrodia, etc.; Potatoes, also commonly known as potatoes, are tubers.

3.The bulb is spherical or oblate spherical, such as water chestnut is the bulb;

4.The bulbs are spherical or oblate, such as fritillary and lily; Onions are bulbs;

Whereas, tuber roots are formed by the local expansion of lateral or adventitious roots. It differs from the succulent straight roots, so that on a single plant, multiple tubers can be formed in multiple lateral roots or on multiple adventitious roots. How to shou wu, dahlias; Sweet potatoes are the roots.

It can be divided into three main points: different distribution, different functions, and different structures.

The distribution is different: the roots are mainly at the base of the plant, generally underground; The stems are mainly in the central axis of the plant, generally on the ground. The role is different:

Roots are mainly used to absorb water and various nutrients in the soil, and also have the functions of support, propagation, and storage; The stem is mainly used to transport water and various nutrients to support the growth of leaves, flowers and fruits in a certain space, and some also have photosynthesis. Different structures: roots can be divided into apical structure, primary structure, and secondary structure; The stems are divided into primary structure, secondary structure, and cross-section.

Some can also be divided into basic structure differences, the roots do not have nodes and internodes, do not grow leaves, the stems will have tubers and rhizomes, etc., with leaves on them, and will also bloom. Secondly, the growth environment is different, the roots grow at the lower end of the plant, and the stem mainly grows at the upper end of the plant. Then the texture is different, the surface of the root will have texture, some can also see the skin pores, and the stem texture is very rough.

In general, there will be knots on the stem, no matter what type of stem it is, you can find knots, but there are no knots on the roots. At the same time, there are also differences in functions, the root is mainly used to absorb water and nutrients, and the stem is used to transport nutrients and water.

Bulbs and tubers are the parts of plants that grow underground. Their function is to store food, and the bulb is an underground stem.

It's like a potato, with a firm skin and a lot of 1 eyes'But there is no stem disk.

My understanding is that bulbs can be hydroponics or soil culture, while tubers can only be soil cultured.

Go and look at the encyclopedia and you'll understand. The scientific method.
