Control and coordination in plants — practice question

When a seed is released from the parent plant, it is in a condition of .................................. , which means that it is metabolically inactive. When water is absorbed by a seed, this stimulates gibberellin production by the .................................. within the seed. The gibberellin stimulates amylase synthesis by cells in the .................................. layer. Amylase hydrolyses starch molecules in the .................................., converting them into soluble .................................. molecules. These molecules are converted to glucose, which is transported to the embryo and provides a carbohydrate source that can be respired to supply .................................. as the embryo begins to grow. Gibberellin produces these effects by regulating genes involved in amylase synthesis. It has been shown that applying gibberellin to seeds can increase the .................................. of the DNA that codes for amylase.
