U | b | DD_0108 | image | teaching_images/types_leaves_6317.png | The diagram shows a leaf identification chart. Plants have leaves in many different shapes, arrangements, margins and venation. Leaves are classified as either alternate, spiral, opposite, or whorled. Plants that have only one leaf per node have leaves that are said to be either alternate or spiral. Alternate leaves alternate on each side of the stem in a flat plane, and spiral leaves are arranged in a spiral along the stem. In an opposite leaf arrangement, two leaves arise at the same point, with the leaves connecting opposite each other along the branch. If there are three or more leaves connected at a node, the leaf arrangement is classified as whorled. The leaf margin is the boundary area extending along the edge of the leaf. There are lots of different types of leaf margins that are important for plant identification. Some common types include entire, crenate and lobate. Leaf venation refers to the arrangement pattern of the veins of the leaf. The pattern of leaf venation is also an important characteristic for the identification of plants. Leaf venation has two common types - reticulate venation and parallel venation. In reticulate venation, all the veins are interconnected, like the strands of the net. In parallel venation, the veins run parallel or nearly parallel to each other and are connected by smaller veins. | 0.654074 |

Image result for types of plate boundaries There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. A divergent boundary occurs when two tectonic plates move away from each other. When two plates come together, it is known as a convergent boundary. Two plates sliding past each other forms a transform plate boundary. | 0.519039 |

R | c | DD_0108 | image | teaching_images/types_leaves_6317.png | The diagram shows a leaf identification chart. Plants have leaves in many different shapes, arrangements, margins and venation. Leaves are classified as either alternate, spiral, opposite, or whorled. Plants that have only one leaf per node have leaves that are said to be either alternate or spiral. Alternate leaves alternate on each side of the stem in a flat plane, and spiral leaves are arranged in a spiral along the stem. In an opposite leaf arrangement, two leaves arise at the same point, with the leaves connecting opposite each other along the branch. If there are three or more leaves connected at a node, the leaf arrangement is classified as whorled. The leaf margin is the boundary area extending along the edge of the leaf. There are lots of different types of leaf margins that are important for plant identification. Some common types include entire, crenate and lobate. Leaf venation refers to the arrangement pattern of the veins of the leaf. The pattern of leaf venation is also an important characteristic for the identification of plants. Leaf venation has two common types - reticulate venation and parallel venation. In reticulate venation, all the veins are interconnected, like the strands of the net. In parallel venation, the veins run parallel or nearly parallel to each other and are connected by smaller veins. | 0.654074 |
