Quiz 3
NCERT Visual ScienceQuestion 1 of 10
Identify the cellular organelle shown in the diagram:
❌ Incorrect. The inner folded cristae identify this as a mitochondrion.
✅ Correct! This is a mitochondrion, recognizable by its folded inner membrane (cristae).
NCERT Visual ScienceQuestion 2 of 10
Which laboratory electrical instrument is shown below?
❌ Incorrect. The unit markings and series design identify this as an ammeter.
✅ Correct! An ammeter connects in series to gauge electric current in amperes.
NCERT Visual ScienceQuestion 3 of 10
Which type of optical lens is illustrated in this diagram?
❌ Incorrect. A lens thicker in the center than at the edges is convex.
✅ Correct! A convex lens is thicker in the middle and converges parallel light rays.
NCERT Visual ScienceQuestion 4 of 10
Which microscopic human blood component is depicted here?
❌ Incorrect. The biconcave disc shape is unique to red blood cells.
✅ Correct! Red blood cells possess a distinct biconcave shape optimized for carrying oxygen.
NCERT Visual ScienceQuestion 5 of 10
What specialized plant epidermal structure is shown open below?
❌ Incorrect. The pore framed by two kidney-shaped cells is a stoma.
✅ Correct! Stomata are surrounded by kidney-shaped guard cells that regulate transpiration.
NCERT Visual ScienceQuestion 6 of 10
Which optical phenomenon splits white light into a spectrum here?
❌ Incorrect. Separating white light into constituent wavelengths via a prism is dispersion.
✅ Correct! Dispersion occurs because different colors bend at slightly different angles in glass.
NCERT Visual ScienceQuestion 7 of 10
Which biological cell type with long axons and dendrites is shown?
❌ Incorrect. Cells with dendrites, a cyton, and a long axon are neurons.
✅ Correct! Neurons conduct electrical impulses throughout the nervous system.
NCERT Visual ScienceQuestion 8 of 10
What type of electrical circuit configuration is demonstrated below?
❌ Incorrect. Components wired across common junction nodes form a parallel circuit.
✅ Correct! In parallel circuits, voltage across every connected branch remains equal.
NCERT Visual ScienceQuestion 9 of 10
Which laboratory apparatus is used to find liquid volume accurately?
❌ Incorrect. A tall cylinder with horizontal volume graduation marks is a measuring cylinder.
✅ Correct! Graduated cylinders provide precise volume readings using liquid meniscus lines.
NCERT Visual ScienceQuestion 10 of 10
What chemical process is depicted on this iron surface?
❌ Incorrect. The red-brown flaky coat of hydrated ferric oxide indicates rusting.
✅ Correct! Iron oxidizes in the presence of air and moisture to form rust (Fe₂O₃·xH₂O). Quiz Complete!

💡 Important NCERT Science Concepts:
- Dendrites: Tree-like sensory extensions that acquire informational signals from receptors or previous neurons.
- Cyton (Cell Body): Contains cytoplasm, the central nucleus, and organelles; transforms chemical inputs into an electrical impulse.
- Axon: A single, long cylindrical fiber that conducts electrical impulses away from the cell body toward target cells.
- Myelin Sheath: Fatty insulating layer formed by Schwann cells that speeds up impulse transmission across the Nodes of Ranvier.
- Synapse: At the axon terminals, the electrical impulse releases neurotransmitter chemicals across the microscopic gap (synapse) to stimulate the next neuron.

💡 Important NCERT Science Concepts:
- Skull (Cranium): Protects the brain; composed of cranial and facial bones joined tightly by immovable (fixed) fibrous joints.
- Ribcage: 12 pairs of curved ribs joined to the breastbone (sternum) in front and the vertebral column behind, protecting the heart and lungs.
- Vertebral Column: Made of 33 small interlocking bones called vertebrae that protect the spinal cord and allow bending and twisting.
- Femur: The thigh bone; it is the longest, heaviest, and strongest bone in the human body.
- Joints: Connect bones to permit locomotion — Ball and Socket (shoulder/hip), Hinge (elbow/knee), and Pivotal (neck).
