Open the article and read it at the level above. Then answer the questions below in your own words.

https://smallwhale.org/articles/sensory-receptor

1. What is the transduction mechanism?
2. What is the types of receptors?
3. What are sensory receptors?
4. Why do we need different kinds of sensory receptors like photoreceptors and hair cells?

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the transduction mechanism?Conversion of physical or chemical stimuli into electrochemical signals (receptor potentials)
2. What is the types of receptors?Photoreceptors, mechanoreceptors, thermoreceptors, chemoreceptors, nociceptors
3. What are sensory receptors?Sensory receptors are special cells that detect things like light, sound, touch, taste, and smell. They send signals to the brain so we can feel and understand our surroundings. They are not just passive; they actively turn energy into electrical messages.
4. Why do we need different kinds of sensory receptors like photoreceptors and hair cells?Different receptors are tuned to specific kinds of energy or chemicals. Photoreceptors in the eye sense light, while hair cells in the ear sense sound waves. This lets us see colors, hear sounds, and more.

Transduction: The process by which sensory receptors convert stimulus energy into electrochemical signals.
Receptor Potential: A localized, graded change in the membrane potential of a sensory receptor cell.
