（4）B
【解析】植物对于我们来说是非常重要的，它可以给动物提供食物。在我们身边植物的种类非常多，他们的叶子的颜色和形状都是不一样的。
(1)细节理解题。根据短文第一段中This is because plants can make food from air, water and sunlight. Animals and men can't make food from air, water and sunlight. Animals get their food by eating plants and other animals可知，植物可以利用空气、水和阳光制作食物，动物可以吃掉植物或是其他的动物来获得食物。这里植物起着重要的作用，由此可知A选项是正确的。
(2)细节理解题。根据短文第三段中Some plants have many small leaves. Others have only a few. There are many kinds of leaves. Leaves are of different shapes and colors可知，不同的植物叶子的形状和颜色是不一样的，故应选D。根据others even have no leaf stalks可知A不对；根据Some leaves have smooth(平滑) edges. Some have a wave-shaped edges. Others have edges like the teeth of a saw可知B不对；根据Leaves are of different shapes and colors可知C不对。
(3)词义猜测题。根据划线单词所在的句子Some leaves have long thin parts at the end, we call them leaf stalks可知，leaf stalks是叶子上的一部分，位于叶子的末端，故它的意思是叶柄。选C。
(4)主旨大意题。短文的第一段告诉我们植物是非常重要的，它可以给动物提供食物；后面的三段讲述的是植物种类繁多，他们的叶子的颜色和形状都是不一样。由此可知B选项概括了短文的大意，比较全面，故应选B。
