Photomorphogenesis is the process by which plants develop and grow in response to light signals, enabling them to optimize their photosynthetic efficiency and adapt to their environment. This process involves a complex interaction of photoreceptors, signaling pathways, and gene expression changes that regulate plant architecture and function.
The embryonic root, also known as the radicle, is the first part of a seedling to emerge from the seed during the process of germination. It anchors the plant and absorbs water and nutrients from the soil, playing a crucial role in the seedling's early development and growth.
An embryonic seed leaf, also known as a cotyledon, is the first leaf or pair of leaves produced by the embryo of a seed plant. Cotyledons are crucial because they serve as food sources for the emerging seedling and are a vital part of early plant growth and development.
