Question

What is phytotron?
A. A device to growth plant under controlled conditions
B. Growing plants in greenhouse
C. Radiation chamber to induce the mutations
D. Apparatus to study the effect of light on plants

Answer 1

Hint: Planting of seedlings under managed state of moisture, heat of soil and air, light, air as well as water distribution and nutrient composition present in soil is known as Phytotron.

Complete answer:
Phytotrons are the chambers having controlled environmental conditions. These are immensely helpful in investigating the growth of plants under various experimental set ups. These are most commonly found in the majority of botanical laboratories. It provides them with environmental control at a small and limited level. Thus, the interaction between plants and its environmental conditions could be effectively studied in these phytotrons. This will provide the account of the effect of several environmental elements on the growth and development of plants.
Phytotron Chambers consist of the controlled environment spaces that can be lit both naturally as well as artificially. Besides this, the chambers are well equipped with the incubators, refrigerators, photoperiod rooms, roomettes and seed germination chambers as well. These provide diverse environmental conditions. They also provide opportunities to carry out various biochemical studies under stable and reproducible conditions. Research based on simulation modeling for which an extensive range of numerous environmental aspects are needed can also be carried out in phytotrons.

Hence, the correct answer is option (A).

Note: Phytotrons are majorly used for exploring the growth and development of plants under diverse environmental conditions. Furthermore, these phytotrons also contribute in the field of research studies like introduction of new varieties and species of plants and plant breeding as well.
