Why? The stratosphere gets most of its heat from the Sun. Therefore, its warmer closer to the Sun. The air at the bottom of the stratosphere is cold. The cold air is dense, so it doesnt rise. As a result, there is little mixing of air in this layer. | 0.40321 |

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. | 0.855078 |

But how does your heart get blood to and from every cell in your body? Your heart is connected to blood vessels such as veins and arteries. Organs that work together form an organ system. Together, your heart, blood, and blood vessels form your cardiovascular system. What other organ systems can you think of? | 0.650499 |

Midrib | d | DD_0110 | image | teaching_images/parts_leaf_557.png | This diagram shows the parts of a leaf. 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. | 0.855078 |
