How do plants use light to grow?

• Plants absorb light to produce carbon dioxide.

• Plants use light to create water for growth.

• Plants use light to generate heat for photosynthesis.

• Plants use light to grow by converting it into energy through photosynthesis.

What do we call the process plants use to make food using light?

• Respiration

• Transpiration

• Fermentation

• Photosynthesis

What happens to a plant if it doesn't get enough light?

• The plant will grow faster and healthier.

• The plant will produce more flowers and fruits.

• The plant will develop a stronger root system.

• The plant will experience stunted growth and may eventually die.

What is a shadow?

• A shadow is a type of light.

• A shadow is a solid object.

• A shadow is a dark area produced by an object blocking light.

• A shadow is a color produced by light.

How do shadows affect the growth of plants?

• Shadows can hinder plant growth by reducing sunlight exposure, affecting photosynthesis.

• Shadows increase water absorption in plants.

• Shadows have no impact on plant growth whatsoever.

• Shadows enhance plant growth by providing cooler temperatures.

What is the difference between transparent and opaque materials?

• Opaque materials can be seen through; transparent materials cannot.

• Transparent materials allow light to pass through; opaque materials do not.

• Both transparent and opaque materials allow light to pass through.

• Transparent materials block light; opaque materials allow light to pass through.

Can light pass through translucent materials?

• Translucent materials block all light completely.

• Light can only pass through opaque materials.

• No, light cannot pass through translucent materials.

• Yes, light can pass through translucent materials.

What type of light do plants need for photosynthesis?

• Blue and red light

• Infrared light

• Green and yellow light

• Ultraviolet light

How do different colors of light affect plant growth?

• Blue light promotes vegetative growth; red light encourages flowering; green light has less effect.

• Yellow light enhances root development

• Orange light is essential for seed germination

• Purple light increases photosynthesis efficiency

What happens to a plant in complete darkness?

• The plant will produce more flowers.

• The plant will thrive and grow faster.

• The plant will die due to lack of photosynthesis.

• The plant will develop a stronger root system.
