Students have asked these similar questions
a. What are the two basic components of phytochrome?
b. Explain how phytochrome responds to different wavelengths of light. How does this account for the phenomenon of photoreversibilty?
Discuss other morphological differences between sunny and shady set-ups of mung bean in relation to phototropic response of plants.
Characteristics

Leaf color
Lime Green
Pale Green
Direction of Growth
Grows upward towards the direction of sunlight
Oriented in the direction of the light but growth is bent downward
Using the provided figure, describe the importance of the two phytochrome systems in controlling de-etiolation and green stem elongation under full sun and shade. Include the key mechanisms and temporal changes in control of this process.

LEAF ADAPTATION The main function of the leaf is in the processes of photosynthesis and transpiration. Apart from these functions, leaf is sometimes adapted to perform other functions. Examples of leaf adaptations are for: a) Support, which could be seen by the presence of tendrils b) Catching insects, by having cup-liked shape of hairs sensitive to touch c) Reproduction, by having meristematic cells able to produce new shoots that will go on to become new individual plants d) Food and water storage, especially found in plants living in dry areas where water is scarce (for example succulent plants, having leaf storing food and water) e) Floatation, for plants living on the water surface, their leaves in general will have air openings on tissues (used for floating) usually found on leaf petiole f) Protection, by having leaves completely or partially modified as thorns Instruction: a) 1. Search for ONE plant species with the following leaf adaptations 2. Give their scientific names…arrow_forward
