Locomotion Flashcards
What is locomotion in animals?
Locomotion is a type of response in animals that denotes movement from one place to another by coordinating muscles, bones, and bone joints.
Why do animals move from one place to another?
Animals move for several reasons, including:
* Finding food
* Avoiding predators
* Dispersal
* Finding favorable habitats
* Reproductive activities
* Seeking shelter
What is the primary motivation behind locomotion for finding food?
Animals are heterotrophs and cannot prepare their own food, thus they move in search of food.
How do animals avoid capture by predators?
Animals undergo locomotion to escape from predators, such as deer fleeing from leopards.
What does dispersal refer to in animal locomotion?
Dispersal refers to the movement of individuals from their birth site to their breeding site and between breeding sites, often due to seasonal changes.
Give an example of an animal that migrates for reproduction.
Common toads migrate between 50 m to 50 km for reproduction.
What is amoeboid locomotion?
Amoeboid locomotion involves the use of pseudopodia, which help in movement and food intake for the organism.
What is ciliary locomotion?
Ciliary locomotion is the movement of organisms like Paramecium using numerous hair-like structures called cilia.
How does Euglena achieve locomotion?
Euglena swims using a single thread-like flagellum that beats to drive water backward, propelling the organism forward.
What role do myotomes play in fish locomotion?
Myotomes are V-shaped muscles that contract and relax alternately, creating waves that propel the fish forward.
How do fins assist in the locomotion of fish?
Fins maintain stability and change direction during swimming. The dorsal and anal fins prevent rolling, while paired fins increase surface area for resistance.
Fill in the blank: Locomotion denotes a change of place in response to _______.
[stimuli]
True or False: Animals are capable of preparing their own food.
False
List the unpaired fins in fish.
- Dorsal fin
- Caudal fin
- Anal fin
What is the main function of the caudal fin in fish?
The caudal fin helps fish change direction by acting as a rudder during swimming.
What is the significance of shelter for animals in relation to locomotion?
Animals move to find suitable shelter necessary for performing physiological functions and maintaining normal life.
