Plant Growth and Light Conditions

The video explores whether plants need light to grow. Two investigators conduct an experiment: one places plants on a windowsill to receive light, while the other places plants in a box to block light. Both sets of plants receive water daily. The results show that plants in the light grow well, while those in the dark struggle. The conclusion is that light is essential for plants to make food and grow healthily.

What is the main question being investigated in the experiment?

• Do plants need water to grow?

• Do plants need air to grow?

• Do plants need light to grow?

• Do plants need soil to grow?

What materials are used in the experiment to test plant growth?

• Seeds and a pot

• Sunlight and a lamp

• Water and a cardboard box

• Soil and fertilizer

Where does the first investigator place their plants?

• In a greenhouse

• In a dark room

• On the windowsill

• Under a lamp

What condition do the plants under the box experience?

• Excessive sunlight

• No light

• Too much water

• Lack of air

What happens to plants when they do not receive enough light?

• They grow sideways

• They grow upwards to find light

• They stop growing completely

• They change color

What is the result for the plants placed on the windowsill?

• They stopped growing

• They turned yellow

• They grew well

• They wilted

Why did the plants in the dark not grow well?

• They had too much water

• They had no light to make food

• They were in poor soil

• They were not watered enough

What would happen to the plants in the dark if left longer?

• They would die

• They would produce seeds

• They would thrive

• They would flower
