Exploring Plant Responses to Gravity and Heat

The video tutorial covers how plants respond to environmental factors like gravity and heat. It explains that plant roots grow downward due to gravity, while stems and leaves grow upward towards light. The video also discusses plant adaptations to heat, such as cacti storing water and conifers releasing seeds after a fire. Students are instructed to complete an assignment on these topics.

What are the two main environmental factors discussed in the video that affect plant growth?

• Soil and air

• Gravity and heat

• Nutrients and temperature

• Light and water

Why do plant roots grow downward?

• To escape predators

• To find more space

• Due to the force of gravity

• To avoid sunlight

What would happen to the roots if a plant is turned on its side?

• They would continue to grow downward

• They would grow sideways

• They would grow upward

• They would stop growing

How do plant stems and leaves respond to gravity?

• They grow sideways

• They grow downward

• They grow upward towards the light

• They stop growing

What is one way plants in warm environments adapt to their surroundings?

• By growing taller

• By storing water in their stems

• By growing thicker leaves

• By shedding leaves

Which type of plant stores water in its stem?

• Conifers

• Ferns

• Cacti

• Mosses

How do some conifers respond to forest fires?

• They release seeds after the fire

• They grow faster

• They change color

• They stop growing

What should students do after watching the video?

• Watch another video

• Complete the assignment titled 'gravity and heat exit ticket'

• Take a break

• Write a report
