(f) Vegetative propagation through leaves
Answers
(a) Single circulation:
Fishes
(b) Uricotelism:
Birds, Reptiles, Land snails
(c) Regeneration:
Echinoderms, Crayfish, Lizards
(d) Buccopharyngeal respiration:
Frog
(e) 3 chambered heart:
Frogs, Lizards, Toads
(f) Vegetative propagation through leaves:
Begonia , Bryophyllum
The examples of the following are given below:
(a) Single circulation- birds, reptiles and fishes
The circulation in organisms that involves passage of blood only once through the heart in one cycle.
(b) Uricotelism- birds, reptiles, kangaroo rat
It is referred to as the removal of nitrogenous waste from the body as uric acid.
(c) Regeneration- echinoderms( sea star), lizards( tail) , humans ( liver)
The regrowth of specific body parts or organs after damage from the remaining parts or tissue.
(d) Buccopharyngeal respiration- frog
Restoration that takes place via buccopharyngeal cavity.
(e) 3 chambered heart- Salamandar( amphibian), also most reptiles except crocodile
Such animals have two atria and one common ventricle. Therefore they have separate channels for deoxygenated and oxygenated blood.
(f) Vegetative propagation through leaves- Begonia and Bryophyllum
A type of asexual reproduction that involves growth of plants from buds originating from leaves.
