✓(i) Mammals are warm-blooded animals. Their skin is covered by hair, sweat glands and oil glands that regulate body temperature. Coelom in mammals is divided into peritoneal, pleural and pericardial cavities. Breathing is through lungs. Four-chambered heart is present. Mammalian heart is made up of four chambers which include two atria and two ventricles. The organisms with this type of heart exhibit double circulation. The deoxygenated blood is completely separated from the oxygenated blood completely. The atria and ventricles are separated by many types of valves which prevent the mixing up of pure blood from that of impure blood. Mammals give birth to young ones through different modes. Mammals have milk-producing glands called as mammary glands to nourish their young ones. Aves are warm-blooded animals. Birds bear three clawless digits. Fore-limbs are modified into wings which aid in flight. Their hind limbs are strong and are developed for walking. Bones are hollow. Body is covered by feathers. Respiration is through lungs. They have four-chambered heart. Avian heart is a four chambered heart and complex in its evolution. It pumps more blood than mammalian heart as birds require lot of energy to fly high in the air. They lay eggs which hatch into chicks.

✓(ii) Gymnosperms are woody trees with cone like appearance. They bear no flowers, no fruits but bear seeds. The seeds are naked as they are not covered by the fruit wall.
Examples: Pinus, Cycas and Cedrus trees
Angiosperms The angiosperms consists of about 2, 50,000 species of herbs, shrubs and trees. The angiosperms are divided into two classes: Dicotyledons and Monocotyledons .
Examples: Grass , Bamboo , Coconut tree.

Aves Vs mammals
Aves, or avians are birds. They lay eggs,while mammals give birth to their young
Aves usually have the ability of flight while mammals don't
Aves have cavities in their bones which allow for flight.
Mammals have sweat glands to maintain body temperature but aves don't
The forelimbs of aves are modified into wings and the hindlimbs are developed to be able to walk on the ground while mammals usually have their forelimbs and hindlimbs on the ground
Aves have a diploblastic (two layered) coelom while mammals have a triploblastic coelom
Gymnosperms Vs Angiosperms
Angiosperms are flowering plants whose seed is enclosed in a fruit which is a modified ovary while Gymnosperms produce naked seeds
Angiosperms are seasonal while Gymnosperms are evergreen
Angiosperms have cotyledons while Gymnosperms don't
