Write difference between the motion of animals and that of plant.
Answers
Answer:
While both plants and animals are living organisms but they can be differentiated with the movement characteristics.
Plants can’t move from one place to another while on the other hand animals can move from one place to another because animals contain specialized protein to promote movement in the body.
Animals have neutron to transfer information from one cell to another while plants just pass electrical and chemical singles to pass information from one cell to another.

Answer:
All living beings are capable of movement. Movement results in the change of position or
posture or place. Movement is essential for all living beings. Plants show only movement while
animals show both movement and locomotion. Plants show movement to protect themselves
from danger, to obtain water, soil, nutrients etc., Animals show movement and locomotion to
escape from danger, to seek and capture food etc.,
Movement and locomotion
Differences Between Movement and Locomotion:
Movement :
- Both plants and animals show movement.
- Only the body parts move.
- Example – Movement of limbs, bending of sunflower towards the sun.
Locomotion :
- Only animals show locomotion.
- Entire body of the organism moves from one place to another.
- Example – Lions run in search of food, snakes crawl here and there.
Movement in Microscopic Organisms
Different kinds of movements in microscopic organisms are:
- Creeping movement as in Amoeba.
- Swimming as in Euglena and Paramecium.
- Bending movements as in Hydra.
- Crawling movements as in Earthworm.
Movement in Frogs
Different types of movement in frogs are:
- Floating
- Swimming
- Leaping
Movement in Birds
Birds:
Two principal types of flight in birds:
- Flapping in which wings move up and down. In this flight there are two principal movements of wings: • Downstroke • Upstroke
- Gliding in which the wings are held stretched in a motionless state.
Insects:
Insects fly in the air with the help of their wings.
- Most insects have two pair of wings – forewings and hindwings.
- Some insects like the houseflies and mosquitoes have only one pair of wings.
- Some insects like the head have no wings and they cannot fly. They move with the help of legs.
- Bats are the only mammals, which can fly.
Movement in humans
The point at which two separate bones meet is called a joint. The different kinds of joints in our body is as follows:
- Immovable joint – Fixed joint.
- Partially movable joint – Allows little movement.
- Movable joint – Varying degrees of movements possible.
Different types of movable joints are:
- Hinge joint.
- Gliding joint.
- Ball and socket joint.
- Pivot joint.
- Synovial joint.
Movement in plants
Movements in plant parts can be broadly classified into two categories:
Tropic movements:
- Geotropism – Growth movements induced by gravity.
- Phototropism – Bending of a plant towards the light.
- Hydrotropism – Movement of a plant towards the water.
- Thigmotropism – Response due to the stimulus of touch.
Nastic movements:
Nastic movements are rapid movements of plant organs in response to a stimulus that results from alterations in cell volume in a specialized motor organ called a pulvinus.
For example, handling of the touch-sensitive leaves of Mimosa pudica results in the folding of its leaflets within a few seconds and is an example of a thigmonastic movement.
