growth movements in plants and movement in animals

Question 1

What is the key difference between plant and animal movement

Answer 1

Plants show growth movements in specific parts.

Animals show locomotion (whole-body movement from place to place).

Question 2

What are growth movements in plants

Answer 2

Slow, irreversible movements due to growth in certain areas.

Example: Seedlings bending toward light (phototropism).

Movement occurs in roots, shoots, tendrils, etc

Question 3

How do germinating seedlings show growth movement?

Answer 3

Shoot grows upward (negative geotropism)

Root grows downward (positive geotropism)

These are guided by stimuli like gravity and light.

Question 4

What is locomotion in animals

Answer 4

Voluntary, fast, and reversible movement of the entire body.

Examples: Walking, swimming, flying.

Involves muscles, bones, or appendages (legs, fins, wings).

Question 5

Why can animals move their whole body but plants can’t?

Answer 5

Animals have muscles and a nervous system for coordination.

Plants lack muscles and nerves, so movement is limited to growing parts.

Question 6

Give one similarity and one difference between plant and animal movement.

Answer 6

Similarity: Both respond to stimuli (light, gravity).

Difference: Plant movement = growth-based and localized; animal movement = muscular and whole-body.
