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. | 0.832304 |

Chemical weathering can also be contributed to by plants and animals. As plant roots take in soluble ions as nutrients, certain elements are exchanged. Plant roots and bacterial decay use carbon dioxide in the process of respiration. | 0.541959 |

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. | 0.832304 |
