Phytotron is a device by which

Options

A. electrons are bombarbed
B. protons are liberated
C. plants are grown in controlled environment
D. mutations are produced in plants

Answer

**Step-by-Step Solution:**

1. **Understanding Phytotron**: A phytotron is an enclosed research greenhouse designed specifically for studying plants under controlled environmental conditions.

2. **Purpose of Phytotron**: The main purpose of a phytotron is to study the interaction between plants and their environment. This includes understanding how different environmental factors affect plant growth and development.

3. **Historical Context**: The first phytotron was developed in California in 1949. This highlights the historical significance and the advancement in plant research technology.

4. **Functionality**: Phytotrons provide all necessary services to conduct a wide range of controlled environment experiments. This means researchers can manipulate variables such as light, temperature, humidity, and soil conditions to observe their effects on plant physiology.

5. **Clarification of Misconceptions**: It is important to note that a phytotron does not involve bombarding electrons or liberating protons, nor is it primarily used for inducing mutations in plants. Its focus is on studying plant-environment interactions.

6. **Conclusion**: Therefore, the correct understanding of a phytotron is that it is a device used for growing plants in a controlled environment and studying their interactions with various environmental factors.

**Final Answer**: Phytotron is a device by which plants are grown in a controlled environment.
