Question

Plants which grow in shade are called
A. Sciophytes
B. Heliophytes
C. Oxylophytes
D. Epiphytes

Answer 1

Hint: An adaptation is just a mutation that has performed well for an animal or plant. In many ways, plants adapt to be capable of surviving or growing in their climate. Discover many instances of plant adaptation that are unique to various environments.

Complete answer:
An epiphyte is an organism that grows from the air, rain, water (in marine environments) or from debris accumulated around it on the surface of a plant and receives its moisture and nutrients. The plant that contains, or capitalizes in, acidic soil is oxylophytes. Due to the development of its own structure and upkeep, Heliophytes are adapted to a habitat of very extreme insolation.
The emergence of a canopy of other plants is due to much of the shade, and this is typically correlated with a totally different climate and richer in soil nutrients than sunny areas. In order to be effective energy-users, shade-tolerant plants are thus adapted.
Sciophytes are also known as photophobic plants and in just 20% sunlight they achieve their saturation stage. Such plants have greater photosynthetic units than solar plants. As shade plants or sciophytes, plants growing in partial shade or low light level are referred to.

Hence, the correct answer is option (A).

Note: In essence, shade-plants adopt methods of efficient use of available sunlight and energy conservation. Thinner leaves with a comparatively higher chlorophyll content per unit leaf volume are adapted to achieve these strategic targets. Lens-shaped epidermal cells concentrate incoming light into and inside the mesophyll. A layer of red cells reflects outgoing light back into the mesophyll, and greater portion of accessible energy to defence-mechanisms against herbivory.
