Frequently Asked Questions
Core Understanding
What is seed formation?
Seed formation is the process by which a plant’s ovule develops into a seed, involving fertilization, embryogenesis, and seed maturation. It is a critical aspect of plant reproduction and development.
What is germination?
Germination is the process by which a seed begins to grow, involving the activation of metabolic processes, seed coat cracking, and the emergence of the radicle and cotyledons. It marks the transition from seed dormancy to seedling establishment.
