A) Name one organ each where growth hormone is synthesized in man and ...
A) Growth hormone or human growth hormone (HGH) is synthesized in the pituitary gland in man, while in plants it is synthesized in the shoot apical meristem.
B) Sequence of events leading to bending of growing shoot in plants:
1. Perception of light: The first step is the perception of unidirectional light by the photoreceptor, which is located in the tip of the shoot.
2. Signal transduction: The photoreceptor then transmits the signal to the elongating cells of the shoot through a signal transduction pathway, which activates the synthesis of the hormone auxin.
3. Auxin synthesis: The auxin is synthesized in the apical meristem and transported down the shoot to the elongating cells.
4. Differential growth: The auxin causes differential growth, with more elongation occurring on the shaded side of the shoot.
5. Bending of the shoot: The differential growth causes the shoot to bend towards the light source.
6. Hormone involved: The hormone involved in this process is auxin.
Explanation:
When a plant is exposed to unidirectional light, the photoreceptor in the tip of the shoot perceives the direction of the light and transmits a signal to the elongating cells through a signal transduction pathway. This signal activates the synthesis of the hormone auxin in the apical meristem, which is then transported down the shoot to the elongating cells. The auxin causes differential growth, with more elongation occurring on the shaded side of the shoot. This differential growth causes the shoot to bend towards the light source, allowing the plant to optimize its exposure to light for photosynthesis. The hormone involved in this process is auxin, which plays a crucial role in the growth and development of plants.
