Question

Anatomical feature of sciophyte is

Answer 1

• Sciophytes are shade-loving trees or plants.
• These plants have larger photosynthetic units than sun plants or heliophytes.
• Sciophytes are also known as photophobous plants and they reach their saturation level in only 20% sunlight.
• Shade-plants essentially follow strategies of optimum use of available energy and conservation of energy.

Adaptation to achieve these strategic goals include

• Thinner leaves with a relatively higher chlorophyll content per unit leaf volume.
• Lens-shaped epidermal cells that focus incoming light into and within the mesophyll.
• A red-cell layer that reflects outgoing light back into the mesophyll.
• Greater allocation of available energy to defence-mechanisms against herbivory.
