1. Many flowering plants use it to regulate the timme of flowering based on the length of day and night (photoperiodism ) and to set circadian rhythms.
2. Phytochromes control many aspects of plant development. They regulate the germination of seeds (photoblasty), the synthesis of chlorophyll, the elongation of seedlings, the size, shape and number and movement of leaves and the timing of flowering in adult plants. Phytochromes are widely expressed across many tissues and developmental stages.
3. It is found in the leaves of many plants.
