Clothing is a language. It tells us about individual people: their personality, their age, their place in society and so on. If we want to know more about society, we can look at traditional clothing.

??? The continent of Africa has a long history and a rich culture, and this is shown in traditional dress. You often find three colours — red, gold and green in the clothing. The first colour stands for the blood of millions of people who suffered as slaves(奴隶); the second is for the rich resources of the African earth; and the third represents the grasslands of home.

The patterns(图案) on the clothing also have a meaning. A common pattern is in the form of a cross “×”, which stands for “unity”. Another pattern is a rectangular box, which represents “strength”.

??? Because clothing has a strong social meaning, people are very careful in choosing what to wear. It would be a serious mistake to wear the wrong clothing, or to wear clothes in the wrong way. For instance, in Ghana, a woman should wear her waistband differently according to the importance of the social event.

Traditional dress also tells us about everyday life. African designs are famous for loose(宽松的) clothing. The climate, with the hot sun and wide temperature ranges(变化), requires that the clothes are comfortable for daily life.

??? Although many people wear western clothes, particularly in the big cities in Africa, traditional dress is very highly valued(评价). This is because it has deep cultural meanings.

It may seem easy to say that plants and animals are different. Any child can tell the difference between  a tree and a dog. But those differences are far deeper than just what they look like. The cells (细胞) that plants are made up of are different. In other words, the cell wall of plants has something special.

First of all, it's important to find that not all plant cells have a cell wall. Besides, there are many differences of a cell wall based on the kinds of plant. The following is meant to be what a plant cell wall is  like.

  The cell wall of a plant is on the outside of the cell membrane (膜). It is usually hard and cannot be bent easily, but the degree of flexibility (韧性) of the cell wall is different. It is based on the special use that the cell has in keeping the plant alive. Cells that make up the trunk of a tree are clearly less flexible than? cells on a leaf.

     Cell walls act in many ways. They serve to protect the plant. They provide support, as well as help in the movement of chemicals and wastes into and out of the cell.  More importantly, they control the water? that goes in and out.  Plants must have good water controlling systems (系统), allowing them to keep water during dry seasons, and get rid of unnecessary water. Plants can't walk around to find water, so  being able to control water is very important.

So there you have it , what a plant cell wall is. Of course, there are many other things that are not talked about here. Knowing more about plant cell wails requires further study and research.
