v. The bacteria which carries out the process of nitrification.
vi. The respiratory pigment present in Erythrocytes
vii. The tissue that transports manufactured starch from the leaves to all parts of the plant.
viii. The structure where photophosphorylation takes place.
(b) Given below are certain biological statements which are incomplete and hence incorrect. Re-write the correct form of the statement by inserting a suitable word/words at the right place. Do not delete any word already given in the statement. Underline the inserted word/words.
Incorrect (i): fertilisation is the product of egg nucleus and sperm nucleus.
Incorrect (ii): Diapedesis is the process of movement of corpuscles through capillary walls.
Incorrect (iii): Destarching a plant means removing the starch from the plant.
Incorrect (iv): Death-rate is the number of deaths of the given population per year.
Incorrect (v): Residual volume is the volume of air left in the lungs after expiration.
Incorrect (vi): The splitting of water molecules into hydrogen ions and hydroxyl ions is termed photolysis.
Incorrect (vii): Transpiration is the loss of water from the leaves of the plant.
Incorrect (viii): A reflex action is a spontaneous response to a stimulus.
(c) Give one point difference between the following pairs on the basis of what is indicated in brackets.
i. Cobalt chloride paper and Goat's bladder (process where it is used).
ii. Rod and Cone cells. (pigment)
iii. Red blood corpuscles and White blood corpuscles (origin)
