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. | 0.763263 |

Vascular plants are further divided into those that reproduce without seeds and those that reproduce with seeds. Seed plants, in turn, are divided into those that produce naked seeds in cones and those that produce seeds in the ovaries of flowers. | 0.609307 |
