Control and Coordination Class 10 Best MCQs

Q: What is the fundamental difference between the nervous and endocrine systems in terms of coordination?

The nervous system uses electrical impulses for rapid, short-term coordination, while the endocrine system employs hormones for slower, longer-lasting effects.

Q: How do reflex actions differ from voluntary actions?

Q: What are the primary functions of the fore-brain, mid-brain, and hind-brain?

The fore-brain is responsible for higher-order functions like thinking and perception. The mid-brain controls visual and auditory reflexes. The hind-brain regulates vital functions like breathing and heart rate, and coordinates movement and balance.

Q: How does the body protect the delicate nervous tissue of the brain and spinal cord?

The brain is shielded by the skull and cerebrospinal fluid, while the spinal cord is protected by the vertebral column.

Q: What is the mechanism behind muscle movement in animals?

Muscle movement occurs due to the contraction of muscle fibers, triggered by nerve impulses and involving the interaction of specialized proteins.

Q: How do plants coordinate their responses to the environment without a nervous system?

Plants utilize hormones and growth movements to respond to stimuli like light, gravity, and touch.

Q: What is the role of auxin in plant growth and movement?

Auxin promotes cell elongation and plays a crucial role in phototropism, causing plants to bend towards light.
