Bract: Bract, Modified, usually small, leaflike structure often positioned beneath a flower or inflorescence. What are often taken to be the petals of flowers are sometimes bracts—for example, the large, colourful bracts of poinsettias or the showy white or pink bracts of dogwood
Plant development is an umbrella term for a broad spectrum of processes that include: the formation of a complete embryo from a zygote ; seed germination; the elaboration of a mature vegetative plant from the embryo; the formation of flowers, fruits, and seeds; and many of the plant's responses to its environment.
Ground Tissue Many different functions are performed by ground tissue including photosynthesis, storage, and support. Ground tissue makes up the majority of the plant structure and is composed of three cell types: parenchyma, collenchyma, and sclerenchyma cells.
