An interaction between aluminium (Al) and calcium (Ca) may be a cause of Al toxicity in plants. The pollen tube is a suitable system …

Germination in Monocots. As the seed germinates, the radicle emerges and forms the first root. In epigeous monocots (such as onion), the single cotyledon will bend, forming a hook and emerge before the coleoptile (Figure 4.6.4.5 4.6.4. 5 ). In hypogeous monocots (such as corn), the cotyledon remains belowground, and the coleoptile emerges first.
