Question

Plants maintain higher levels of phytochrome at their growing tips where phytochrome plays important roles in growth responses to light. Phytochrome levels are also high in areas of the plant that are "greening". What does this suggest about the role of phytochrome in these "greening" zon?

Answer 1

Phytochrome is facilitating the transcription and translation of photosynthesis related proteins

Step-by-step explanation:

Phytochromes are a type of photoreceptors usually seen in fungi, bacteria ad in plants generally. They hep these organisms for the detection of light. They have a high level of pytochrome and this plays a very vital role to ensuring that plants grow as they see light. Also, for areas of plants that already have "green zones", phytochrome also plays a criucial role in this greening.
