Adaptation of Plants to Abiotic Factors

Front

What are abiotic factors that influence living organisms in an ecosystem?

Back

Light, temperature, wind, water, air, and soil.

Front

How does light energy affect the growth and distribution of plants?

Back

It regulates surface temperature and influences photosynthesis, transpiration, and water absorption.

Front

What is photosynthesis?

Back

The process by which plants convert light energy into chemical energy using chlorophyll to prepare carbohydrates from carbon dioxide and water.

Front

What are the best wavelengths of visible light for photosynthesis?

Back

Blue range (450-500 nm) and red range (600-700 nm).

Front

What is the role of chlorophyll in plants?

Back

Chlorophyll absorbs blue and red light and reflects other colors, which is why plants appear green.

Front

What is respiration in plants?

Back

The process by which cells obtain chemical energy by consuming oxygen and releasing carbon dioxide.

Front

How does light affect transpiration in plants?

Back

Light influences the opening and closing of stomata, which regulates water loss through transpiration.

Front

What are the three groups of plants based on photoperiodic responses?

Back

Short day plants, long day plants, and day neutral plants.

Front

What is heliotropism?

Back

The movement of plant parts towards the light source.

Front

What is the effect of temperature on plant growth?

Back

Temperature affects the development and rate of growth, with each species having a specific temperature range.
