What's the difference between flowers and grass?

There is no essential distinction between flowers and grass. Flowers are selected from grass. Flowers come from grass. Only the two focus on different visual impact, grass generally refers to relatively low foliage plants; flowers for flowering plants reproductive form, generally refers to ornamental value of herbs.

1. What are herbs?

The xylem in the stem is underdeveloped, contains few lignified cells, and has weak support. Herbs are generally very short in shape, short in life, weak in stem, most of the above-ground parts or whole plants die at the end of the growing season. According to the length of the life cycle, they are divided into annual, biennial and perennial herbs.

2. What is a herb with ornamental value?

Flowers, ornamental value of herbs, is used to appreciate the general term for plants, like the sun and cold, with reproductive function of short branches, there are many types. Flowers typical, bearing calyx, petals, and stamens and pistils producing reproductive cells on a short axis of finite growth. Flowers by corolla, calyx, receptacle, pistil composition, there are a variety of colors, some grow very gorgeous, there is fragrance.

Some scholars believe that gymnosperms are also "flowers", while most people think that angiosperms have real flowers, so angiosperms are also called flowering plants. The flower parts are not easily affected by the external environment. For a long time, the flower morphology has been regarded as the main basis for classification, identification and systematic evolution of angiosperms.

3. What is a woody plant?

Woody plants are sturdy plants whose roots and stems are thickened to form a large number of xylem, and most of the cell walls are lignified. Woody plants can be divided into three types according to their plant height and branching position:

1, semi-shrub: perennial plants, only the base of the stem lignification, and the upper part of the grass, winter withered, such as peony;

2. Shrubs: relatively short, trees below 5 meters high, branches close to the base of stems, such as tea, rose, hibiscus, etc., with evergreen shrubs and deciduous shrubs;

3. Trees: tall and upright trees with a height of more than 5.5 meters. Trunk obvious, branched parts higher, such as pine, fir, maple, camphor and so on.
