Explain the role of the plant cell wall in limiting osmotic flow into the cell?
由于卷子上的问题是英文,所以用英文问会比较准确,翻译成中文的大概意思是:植物细胞壁在受限制的渗透过程(从外界流入细胞内)扮演什么角色?本人英文翻译成国文有点点问题,见谅~

题目为:解释植物细胞细胞壁在限制渗透液内流入细胞的过程中起到何种作用?
限制大分子物质等的触及细胞,及构成缓冲区域,以及有助于保持植物细胞的正常形态吧.

植物细胞细胞壁主要由纤维素构成,质地坚硬.理论上,如果没有细胞壁的存在,因为渗透压的作用,液体会流入植物细胞(细胞内外物质浓度差使然),进而导致植物细胞的胀裂.细胞壁的存在限制了植物细胞可能胀大的范围,从而阻止了植物细胞的扩张.
这么一大段总结起来一句话,有助于保持植物细胞的正常形态!

The plant cell wall is mainly composed of cellulose which is a tough substance. Theoretically, in the absence of cell wall, due to osmotic pressure, water will flow into plant cell (concentration differences in substrates), and results in the explosion of plant cells. The presence of a tough cell wall limited the range of which the plant cell could enlarge, and thus prevents expansion of plant cells.
