The video tutorial explains the differences between movement in animals and plants, highlighting that animals exhibit both locomotion and movement, while plants only show movement. It categorizes plant movements into tropic and nastic movements, providing examples such as phototropism, geotropism, and thigmotropism for tropic movements, and photonasty, thigmonasty, and thermonasty for nastic movements. The video also discusses specific plant responses to stimuli like light, gravity, chemicals, and touch.

What is the primary difference between locomotion and movement?

• Locomotion is only observed in aquatic animals.

• Locomotion is faster than movement.

• Locomotion is a characteristic of plants, while movement is a characteristic of animals.

• Locomotion involves a change in position of the whole organism, while movement is any change in shape, size, or direction of body parts.

Which type of tropic movement is observed when a plant bends towards light?

• Chemotropism

• Phototropism

• Thigmotropism

• Geotropism

What drives the growth of a pollen tube towards the ovule?

• Water

• Chemical signals

• Gravity

• Light

How do roots respond to a water source in the soil?

• They stop growing.

• They grow upwards.

• They grow towards the water source.

• They grow away from the water source.

What type of movement is exhibited by plant tendrils coiling around a support?

• Phototropism

• Thigmotropism

• Geotropism

• Hydrotropism

Which plant movement is characterized by non-directional responses to stimuli?

• Geotropism

• Tropic movements

• Nastic movements

• Locomotion

What is the response of the touch-me-not plant when touched?

• The plant changes color.

• The plant grows taller.

• The leaves droop down.

• The leaves open up.
