The Blade is the broad flat part of the leaf. The Petiole is the stemlike part of the leaf that joins the blade to the stem. The Stipules are two small flaps that grow at the base of the petiole of some plants. A leaf has several veins. Veins carry food and water in a leaf. They also support the blade. The large central vein which extends from the base of the blade to its tip is called the Midrib. Smaller veins connect the midrib to other parts of the blade. | 0.800475 |

They thought this because fungi had several similarities to plants. For example: Fungi and plants have similar structures. Plants and fungi live in the same kinds of habitats, such as growing in soil. Plants and fungi cells both have a cell wall, which animals do not have. | 0.633798 |
