Question 4 :
When we touch the leaves of “touch-me-not” plant, they begin to fold up and droop. How does the plant communicate the information of touch?
(a)The plant uses electrical signals to transfer information from the external environment to cells.
(b) The plant uses electrical- chemical signals to transfer information from cell to cell.
(c) The plant uses electrical- chemical signals to transfer information from tissue to specialized cells.
(d) The plant uses electrical signals to transfer information from cell to specialized tissues.
Correct Answer – (B)
Question 5 :
Which option correctly shows the order of events when a bright light is focused on our eyes?

(c) Bright light → receptors in eyes → sensory neuron → motor neurons → spinal cord → eyelid closes
(d) Bright light → receptors in eyes → spinal cordà motor neurons → sensory neuron → eyelid closes
Correct Answer – (A)
Question 6 :
Which of the following statements is correct about receptors?
(a) Gustatory receptors detect taste while olfactory receptors detect smell
(b) Both gustatory and olfactory receptors detect smell
(c) Auditory receptors detect smell and olfactory receptors detect taste
(d) Olfactory receptors detect taste and gustatory receptors smell
Correct Answer – (A)
Question 7 :
Organisms depend on hormones as well as electric impulses for the transmission of signals from the brain to the rest of the body. What can be a likely advantage of hormones over electric impulses?
(a) It is secreted by all types of cells present in the body.
(b) It is secreted by stimulated cells and reaches all cells of the body.
(c) It is relayed to the target organ at a faster rate than electric impulses.
(d) It does not depend on an external stimulus to be generated in the cells.
Correct Answer – (B)
