Gibberellin is the primary hormone that promotes seed germination by breaking seed dormancy and stimulating the growth of the embryo.

Embryogenesis is the process of development of an embryo from a zygote, which eventually leads to the formation of a mature plant.

The apical meristem is responsible for the continuous growth of shoots, including the stem and leaves, by producing new cells and tissues.

Auxin is the primary hormone responsible for apical dominance, which is the inhibition of lateral shoot growth by the main stem.

Pollination is the process by which pollen grains are transferred from the male anther to the female stigma, enabling fertilization.

Ethylene is the primary hormone involved in fruit development, promoting ripening and softening of fruits.

Cellular differentiation in plants is regulated by a combination of transcription factors, hormones, and environmental signals.

Abscisic Acid (ABA) is the primary hormone involved in the regulation of leaf senescence, promoting the breakdown of chlorophyll and the reabsorption of nutrients from leaves.

Rhizogenesis is the process by which new roots are formed from existing roots, enabling the plant to expand its root system.

Florigen is the primary hormone that regulates flowering in plants, promoting the transition from vegetative growth to reproductive growth.

Phototropism is the phenomenon of plants responding to the direction of light, with shoots growing towards the light and roots growing away from it.

Caulogenesis is the process by which new shoots are formed from existing shoots, enabling the plant to produce branches and increase its photosynthetic capacity.

Ethylene is the primary hormone involved in the regulation of fruit ripening, promoting the breakdown of cell walls and the accumulation of sugars and pigments.

Phyllotaxis is the arrangement of leaves on a plant stem, which can vary depending on the species and growth conditions.

Auxin is the primary hormone involved in the regulation of root growth, promoting the elongation and differentiation of root cells.
