Lucocytes (WBCs) are considered as true cells because
they possess nucleus
they do not contain haemoglobin
they show great power of movement
they are responsible forphagocytic activity
The function of surfactant is/are
facilitating lung expansion
maintaining the stable size of the alveoli
to reduce the surface tension on the alveoli
all of the above
The plant undergoes wilting when
xylem is blocked
cambium is blocked
phloem is blocked
some roots are reduced in number
During muscle contraction
size of 'A' bands remain same
size of 'H' zone becomes smaller
size of 'I' band decreases
diameter of fibre increases
Two chief functions of the leaves are
photosynthesis and respiration
photosynthesis and transpiration
transpiration and respiration
respiration and digestion
