Question

Name the various environmental factors that affect plant life. Describe how any one of these factors influences plants?

Answer 1

Three main categories of environmental factors influence plant growth and development.

1. Climatic factors: Light, temperature, water, and atmospheric gases.
2. Edaphic (Soil) factors: Soil texture, moisture, nutrients, and pH levels.
3. Biotic factors: Interactions with other living organisms (like insects or fungi).

Temperature plays an important role in determining where and how a plant grows. Here is how it influences them:

• Metabolic rates: It regulates the speed of photosynthesis and respiration. Every plant has an “optimal range” where it grows best.
• Tolerance: Some plants are stenothermal, meaning they can only survive within a very narrow temperature range. Major fluctuations can be fatal for them.
• Growth and distribution: Extreme heat or cold can halt plant growth. This factor ultimately decides which plant species can grow in specific parts of the world.
