Detailed explanation-1: -Plants with alternate and spiral leaf arrangements have only one leaf per node. In an opposite leaf arrangement, two leaves connect at a node.
Detailed explanation-2: -plant anatomy The number of leaves that appear at a node depends on the species of plant; one leaf per node is common, but two or more leaves may grow at the nodes of some… …the stem is called a node, and the region between successive nodes is called an internode.
Detailed explanation-3: -The alternate type of phyllotaxy is the arrangement of leaves in which a single leaf arises at each node in alternate manner.
Detailed explanation-4: -In alternate-leaved plants, the leaves are single at each node and borne along the stem alternately in an ascending spiral. In opposite-leaved plants, the leaves are paired at a node and borne opposite to each other.
Detailed explanation-5: -Alternate Phyllotaxy Here, only one leaf is present at a single node. This means each leaf will arise from a different node from the sides.
