There are more than 400,000 kinds of plants on earth. Some plants are as big as tall buildings; others are as small as rice. Plants are key parts of the food circle. They play an important part in nature because they give out oxygen, the gas that all animals need for breathing. What is a plant? Most people have no difficulty finding the differences between an animal and a plant. That is because animals can move around, but plants can't. What makes a plant a plant? Like animals, plants are living things that are made up of lots of cells.
Unlike animals, plants make their own food by photosynthesis. Most plants have roots, stems, and leaves, and most plants reproduce by growing flowers and making seeds. All plants need energy to stay alive and grow, and they get it from sunlight instead of food. How does a plant grow? Most animals grow in a certain way, and genes control their growth. That is to say, even when they are small, it's easy to know what they will look like after they grow up. Plants are different. Their growth is controlled by genes too, but their final shape also depends on where they live. For example, a tree can be big and round if it grows up in an open space, but much taller and thinner if it grows in the woods with other trees all around. Plants are unable to move from one environment to another, so it is important that they are able to get used to the environment.

解析
【分析】本题为科普类英语阅读理解，需结合原文段落内容，针对细节查找、词义猜测、写作手法判断、细节理解、文章出处等考点逐一分析选项，定位关键信息后得出答案。
【解析】
6. 细节理解题：定位第一段，原文提到“more than 400,000 kinds of plants”对应A选项，“Some plants are as big as tall buildings; others are as small as rice”对应B选项，未提及种树的方式，因此选C。
7. 词义猜测题：划线词所在句意为“植物通过______自己制造食物”，结合常识及上下文，植物制造食物的过程是光合作用，因此选C。
8. 写作手法题：第二段多次将植物与动物对比（如“Unlike animals, plants make their own food...”“Most animals grow... Plants are different...”），运用了比较的手法，因此选A。
9. 细节理解题：A选项原文未提及花和种子是最重要部分；B选项原文指出动植物生长方式不同；C选项对应最后一段“it is important that they are able to get used to the environment”，因此选C。
10. 文章出处题：文章围绕植物的科普知识展开，最可能出自科学杂志，因此选A。
