Spike of spikelet inflorescence is characteristic of which plant?

A spike of spikelet inflorescence is characteristic of plants belonging to the grass family (Poaceae), especially cereals such as wheat, barley, and other grasses. In this type of inflorescence, small flower clusters called spikelets are arranged directly on the main floral axis without individual stalks.

In wheat (Triticum), the main axis carries several spikelets, and each spikelet contains one or more small flowers called florets. This arrangement helps grasses produce and protect their reproductive structures efficiently.

The spike of spikelets is an important identifying feature in plant morphology and is commonly studied while learning about different types of inflorescences in flowering plants (angiosperms). It helps students understand how flowers are arranged for reproduction, pollination, and seed formation.
