Vegetative Propagation: Asexual reproduction of plants using methods like cuttings, avoiding seed production.
Floral Meristem: The specialized growing tip of a flower bud responsible for producing floral organs.
Nectaries: Glands within flowers that produce nectar, a sugary liquid essential for many pollinators.
